Un compañero de tu salón presenta una condición especial llamada gigantismo, ya que su estatura es mucho mayor que la de los demás compañeros de la misma edad, el médico descarta que sea un problema hereditario. Podemos suponer que este estudiante tiene insuficiencia de la hormona ____________________que la secreta la glándula _____________y se encuentra en la ___________. Esta hormona no ingresa a las células en su mecanismo de acción por ser __________________.
Answer:
Podemos suponer que este estudiante tiene insuficiencia de la hormona de crecimiento (somatotropina) que la secreta la glándula hipófisis y se encuentra en la base del cerebro. Esta hormona no ingresa a las células en su mecanismo de acción por ser peptídica o no esteroidea.
Explanation:
En este caso presentado se encuentra una situación diferente a lo que sucede en el gigantismo: hay un problema hormonal en donde la hormona de crecimiento es secretada de manera excesiva. Recibe el nombre de acromegalia cuando sucede después del cierre de la epífisis del hueso, luego de la edad de crecimiento.
The immune response of a host against an invading bacterium is often triggered by surface components on the bacterium that are recognized as "non-self" or "foreign" by the host. These non-self components, often protein or polysaccharide in nature, are referred to as antigens. The host responds to these antigens by making antibodies that will react with invading bacteria and mark them or tag them for destruction by phagocytes.
Indicate the bacterial structures that are likely to be antigens, to which host antibodies bind, marking the invader for phagocytosis
a. fimbriae
b. ribosomes
c. cell wall
d. plasmids
e. flagella
f. capsule
g. nucleoid
Answer:
The correct answer is :
a. fimbriae
e. flagella
c. cell wall
f. capsule
Explanation:
There are several bacterial structures that are binds to the host cells and likely to be antigens to which specific antibodies attached to mark or destruct them by phagocytes.
These bacterial structures are common in the fact that all these structures have binding ability to the host cells and invading them some of these structures are : fimbriae, cell wall, flagella, and capsule that are attached to antibodies and cell of the host.
Thus, the correct answer is :
a. fimbriae
e. flagella
c. cell wall

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.

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.

[tex] \Large{ \boxed{ \bf{ \color{blueviolet}{Required \: answers:}}}}[/tex]
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.

2. Which of the following statements is true of persuasive messages?
A. People tune out repetitious messages, so they quickly lose effectiveness.
B. Messages presenting a one-sided argument tend to be more effective than "he said; she said" messages.
C. Messages that offer a remedy for a person's fears tend to be effective.
D. An effective message will reach all audiences, regardless of background.
Answer:
C. Messages that offer a remedy for a person's fears tend to be effective.
Explanation:
The manner in which the message is presented. Presenting two sides of an argument makes the message seem more believable and persuasive than presenting just one side. Such an approach gives the message a sense of being impartial and factual. *Presenting a fear factor also may persuade people. For example, ads for different kinds of medicines present the dangers lurking around us as they offer a remedy.
Repetition. Repeated exposure to stimuli—like ads—is more likely to have favorable effects on attitudes than infrequent exposure. That’s why companies spend lots of money making sure their ads run again and again and why they have their logos and messages on race cars, buses, and billboards. The more often you see or hear a message, the more likely you are to have a positive attitude toward it.
Messages that offer a remedy for a person's fears tend to be effective is true for persuasive message. Therefore, option (C) is correct.
What is a persuasive message?To persuade someone means to move them emotionally or to motivate them to act in a certain way by presenting them with arguments that convince them to accept your viewpoint or act in the way you want them to. A persuasive message can be either spoken or written and is a form of communication that persuades the reader or listener to behave or act in a particular way.
The first step in convincing someone is to motivate them. If persuasion is a process, and the action of your audience (such as purchasing a product or service) is the goal, then motivating them to accept an argument or a series of positions leading to the decision that you want them to adopt is one way to help achieve that goal. If you want them to buy a product or service, for example, this would be an action.

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.

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.
