Hello. This question is incomplete. The full question is:
Imagine you discover a new human parasite like T. gondii that forms cysts in the brain. You suspect it is altering human behavior. You also determine that it is transmitted through sharing food. In what ways would you predict that it zombifies its hosts (alters their behavior)?
a. It should make them feel sick and rest in bed.
b. It should make them want to host more people for social dinners.
c. It should make them want to prepare meals more.
d. It should reduce their sanitary practices (e.g. washing hands) while preparing food.
e. It should make them want to horde food.
Answer:
a. It should make them feel sick and rest in bed.
b. It should make them want to host more people for social dinners.
c. It should make them want to prepare meals more.
d. It should reduce their sanitary practices (e.g. washing hands) while preparing food.
Explanation:
The options shown above are the only ones that show possible changes in personal behaviors related exclusively to the behavior of a person, who may be suffering from the damage caused by a parasite in the brain. The "e" option does not represent a change in behavior and does not depend exclusively on a sick individual due to the action of a parasite.
As you may already know, the brain governs our body in all factors, for this reason, cysts in this organ can trigger behavioral changes.
Answer: a. It should make them feel sick and rest in bed.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis, a generally mild but potentially fatal disease, especially in cats and human fetuses. Cats and other felines are considered their ultimate hosts because the sexed phase of their life cycle takes place there, making these animals the primary hosts of the parasite. The asexual phase of the life cycle can occur in any warm-blooded animal, such as other mammals and birds. Therefore, toxoplasmosis is a parasitic zoonosis.
Parasites invade the cells, forming a compartment called the parasitophore vacuole which form cysts in tissues, especially in the muscles and brain. Because the parasite is inside the cells, the host immune system does not detect these cysts. Antibiotic resistance varies, but cysts are difficult to eradicate entirely. Therefore, T. gondii spreads within these vacuoles through a series of binary divisions until the infested cell eventually breaks free.
Some people have flu-like signs and symptoms, which may be:
Swollen lymph nodesHeadacheFeverFatigueWidespread painIn people with impaired immune systems, symptoms may also include:
ConfusionLack of coordinationConvulsionsBlurred vision caused by intense swelling of the retinaIn recent years, several investigations indicate that the parasite can cause changes in the behavior associated with impulsivity, and personality disorders. So, we could predict it zombifies the host by changes in the behavior, because of the damage caused by a parasite in the brain. It is important to consider that the brain governs the body, and cysts found there can trigger these changes.
Examine the statement. A scientific theory can become a scientific law, but a scientific law cannot become a scientific theory. If the statement is true, select “True.” If it is false, select the option that is true 1.) True 2.) A scientific theory can become a scientific law, and a scientific law can become a scientific theory. 3.) A scientific law can become a scientific theory, but a scientific theory cannot become a scientific law. 4.) A scientific theory cannot become a scientific law, and a scientific law cannot become a scientific theory.
Answer:
It's true.
Explanation:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
When the scientists test the idea, they develop a theory by following a set of logical steps. A theory becomes a scientific law once it has been rigorously examined and accepted. Thus, option A is correct.
What A scientific theory can become a scientific law?One prevalent fallacy is the idea that hypotheses eventually become laws. Despite the number of supporting examples, hypotheses do not actually become laws after repeated testing.
Scientific laws, like theories, explain occurrences that the scientific community has determined to be verifiably true. In general, laws explain what will occur in a specific circumstance and are proven by a mathematical equation, whereas theories explain how the phenomenon occurs.
Therefore, A testable explanation of a natural event is what constitutes a scientific hypothesis. The concept of gravity, for instance, explains why an apple always falls to the ground when.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.
A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.
Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.
Thus, the correct answer is - amoeba: pseudopod; euglena: flagellum; paramecium: cilia
Give examples of types of pollution and the effects on water quality (examples: sedimentation, stormwater runoff, naturally and human induced occurrences of arsenic in groundwater)
Answer:
Sewage, oil, pesticides and fertilizers affect water quality.
Explanation:
There are three types of pollution i. e. air pollution, soil pollution and water pollution. Smoke and smog are present in the air is the example of air pollution, waste product, using of pesticide and industrial dumping are the example of soil pollution and chemicals in water due to runoff of fertilizer, sewage and oil are the main agents of water pollution. These three types of pollution adversely affected the water quality. Water quality will be affected when the fertilizer or pesticides runoff from land to water bodies. Sewage and oil also lowers the quality of water.
how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction
The mass of the products is larger than the concentration of the reactants in an energy absorption process.
The power of the reaction mixture is larger than the radiation of the outputs in an energy-releasing process.
As substances disrupt bonds, energy released, and then when outputs make new bonds, release energy.
Exothermic processes release energy, whereas endothermic reactions consume it. There is no general change in the quantity of energy throughout a chemical process, whether it collects or releases it.

Answer:
Temporal isolation
Explanation:
Temporal isolation, a type of reproductive barrier caused by variations in the timing of mating receptivity, activity, or fertility, prohibits interbreeding between different but closely related species.
What is the temporal barrier in reproductive isolation?In biology, temporal isolation is a form of reproductive isolation mechanism that prevents members of closely related species from mating and creating hybrid offspring.
Temporal isolation refers to the situation where two or more species reproduce at various periods. For instance, three different types of orchids live in the same rain forest.
This mechanism arises from differences in the timing of crucial reproductive events.
Therefore, Temporal isolation reproductive barrier will most likely be working against that possibility.

Assist in the early stages of protein and lipid production
The function that the Golgi bodies provide for the cell is that they assist in the early stages of protein and lipid production. The correct option is D.
What are Golgi bodies?The Golgi apparatus is basically an organelle encountered in most eukaryotic cells. It is also referred to as the Golgi complex, Golgi body, or simply the Golgi.
It is a component of the cytoplasmic endomembrane system that packages proteins into membrane-bound vesicles before they are transported to their destination.
Proteins produced by ribosomes in the ER are packed in the Golgi apparatus, where lipids wrap them in a membrane that is then exported from cells.
Molecules entering the Golgi are charged, stored, and then released back into the cytoplasm (secretory vesicles).
The Golgi bodies function in the cell by assisting in the early stages of protein and lipid production.
Thus, the correct option is D.

The primary function of the lymphatic system is The primary function of the lymphatic system is the production and distribution of plasma proteins. the transport of hormones. the production and maturation of leukocytes. circulation of nutrients and dissolved gases. defending the body against both external and internal threats.
Answer:
The primary function of the lymphatic system is defending the body against both external and internal threats.
Explanation:
The set of tissues and organs that participate in the immune response is known as the lymphatic system. Its main functions are to maintain the volume of blood and participate in the defense of the organism. It is made up of organs, vessels, nodes and lymphatic tissue. This system fulfills three basic functions: Defense: in the lymph nodes, the lymphocytes reproduce to respond to antigens; fat absorption: most of the fats are absorbed by the lymphatic system and subsequently transported to the blood and capillary exchange: it recovers substances that the blood flow has lost in the capillary exchange.
The principal function of the lymphatic system is to remove strange or damaging substances from tissues and eliminate them. The correct option is defending the body against both external and internal threats.
------------------------------
Among other functions of the lymphatic system, its principal one is the removal of damaged cells, cancer cells, and protection of the body against the virus, bacteria, and fungi that might affect it.
The lymphatic system remove these elements from the tissues for their elimination.
All these strange microorganisms and waste substances get filtrated in the lymphatic ganglia.
Ganglia are small organs located all along with the net of lymphatic vessels, that function as lymph accumulation centers.
Lymph passes through these organs and gets filtrated and purified of waste substances.
Inside each ganglion, the lymphocytes T and lymphocytes B help the organism to fight these infections.
B cells produce antibodies that impede infection propagation by trapping the microorganisms and destroying them.
Most lymphatic ganglia are grouped near the neck, underarm, and groin.
They are also grouped in the chest, abdomen, and pelvis, where they filter blood.

Sebastian wants to make ball-and-stick models of the four macromolecules. He has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen Which molecule could he make that consists of long chains of red and black colored balls? carbohydrates lipids nucleic acids proteins
Answer:
lipids
Explanation:
There are four major biological macromolecules in living systems viz: carbohydrate, proteins, lipids and nucleic acids. These macromolecules play a significant role in the optimal functioning of every living organism. Like every other polymer, these macromolecules are made up of simpler units called monomers that defines their chemical structure. In turn, the monomers consists of chains of chemical elements held together.
According to the question, Sebastian has colored balls that represents the elements contained by each of these macromolecules. The colored balls and the elements they represent are as follows: Red: hydrogen, Black: carbon, Purple: oxygen, and Green: nitrogen.
Lipids are structurally made up of fatty acids and glycerol, which are long chains of carbon and hydrogen elements with a relatively small percentage of oxygen in the structure. An example is palmitic acid, which has a structural formula: CH3(CH2)14COOH
Hence, Sebastian could make a LIPID macromolecule, which consists of long chains of red (hydrogen) and black (carbon) balls since lipids are mostly made up of carbon and hydrogen elements in their structure.
Carbohydrates are composed of more percentage of oxygen in their structure. Hence, a long chain of only red (hydrogen) and black (carbon) balls cannot make them. Proteins and nucleic acids are made up of additional nitrogen and phosphorus elements in their structure.
Answer:
B. Lipids
Explanation:
Lipids contain carbon and hydrogen.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins
Answer:
C. glycoproteins
Explanation:
Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

1) An eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body. There are two types of eclipses on Earth:
An eclipse of the moon An eclipse of the sun.2) Most years have 4 eclipses, which is the minimum number of eclipses that take place in a year; 2 of these 4 eclipses are always solar eclipses. While rare, the maximum number of eclipses that can take place in a calendar year is 7.
3) Differences:-
Solar eclipses happen at new moon. Lunar eclipses happen at full moon.Solar eclipses are only visible from a narrow strip of land over which the Moon shadow passes. Lunar eclipses are visible from the whole nighttime hemisphere.Solar eclipses can be total, annular, hybrid or partial. Lunar eclipses can be total, partial and penumbral.Solar eclipses can only be safely be viewed with the naked eye during totality. Lunar eclipses can always be safely viewed with the naked eye.The Moon's surface can't be seen during a solar eclipse, but it can be during a lunar eclipse.4) Moon phases:
We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth! As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
5) The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. Instead of light hitting the moon’s surface, Earth's shadow falls on it. This is an eclipse of the moon -- a lunar eclipse.
Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.
6) The moon can look red during a total lunar eclipse because of sunlight that's filtered and refracted by Earth's atmosphere.
7) 50% of the lunar surface is always illuminated by Sun. Because half of the moon surface is lit, rest we can't see.
8) When the moon passes between the sun and Earth, it can create a solar eclipse. When the disk of the moon masks the disk of the sun, it creates a total solar eclipse. Lunar eclipses occur when Earth passes between the sun and the moon. During a lunar eclipse, the moon turns dark red due to the deviation of the sun's rays caused by Earth's atmosphere. Lunar eclipses occur more often and last longer.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
Answer:
skin acts as a protective barrier, therefore it does not secrete hormones
Skin does not secrete hormones. Thus, the correct option is B.
What are Hormones?Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.
Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.
The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.
Therefore, the skin does not secrete hormones. Thus, the correct option is B.
