activity?

A. A temperature below 30°C

B. A temperature of 35°C

C. A temperature above 50°C

D. A temperature of 20°C

Answer:

Near to the middle.

Explanation:

Most finches have beak depths close to the middle, which benefits the feeding and justifies the reason why most of these birds have this beak extension.

As you know, tendons are birds of the family of fringilids, they are known for having a very pleasant song, which allows people to wish to have them at home, as a pet.

They feed on grass seeds and insects. This type of food is benefited by the medium sized beak, allowing the tendons that have this type of beak to have survival advantages.

Answer:

Most of the finches have beak depths near the middle extreme of the range since the graph shows us that most of the finches (270) have a beak depth of 10mm, so we can infer most of them have a medium sized beak, which provides them many survival advantages.

Answer:

The taxonometric way of classifying organisms is based on similarities between different organisms. ... Scientists looked at the characteristics (traits) that each organism had in common. They used the shared derived characteristics of organisms. Scientists were then able to find the common ancestry of the organisms.

Millions of the organisms are present on Earth and they are classified into categories by the division of them into the different kingdoms based on their characters and traits.

There are total 5 kingdoms in total given by R.H. Whittaker.

Kingdom monera is the first kingdom in which the single celled organisms are divided in and they are basically the first ones to invade the planet as well. These are single celled prokaryotic organisms which do not have well defined organelles.

Later on the prokaryotes along with the protists, kingdom plantae in which all the plants are included and the kingdom animalia in which all the animals are included in. Based on the sub categories they are later divided into the various categories such as mammals with the mammary glands are divided into phylum mammals.

Answer:

By increasing the amount of solutes in the intestine, these will increase in the bloodstream, that is, there will be a higher concentration of solutes in the volume.

To compensate for this phenomenon, the brain will coordinate, together with the tongue, the sensation of "dry mouth or thirsty mouth" in order to encourage the individual to consume water.

Once the individual takes the water, it is absorbed at the intestinal level and the general systemic volume increases, thus generating an increase in blood pressure, body hydration and a decrease in the concentration of solutes in the blood.

Explanation:

The renin angiotensin aldosterone system is a system that indirectly regulates the sensation of thirst and blood volume. This system connects the lung, with the cardiovascular system and the kidneys since they all work together.

When a person eats or eats a very salty food, or even drinks very sugary drinks or with salts and minerals, all this is absorbed, and this is how after ingestion thirst is triggered to compensate for the amount of solutes it has a rise in volume.

Answer:

toms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Explanation:

An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (amu) or one Dalton.

Each electron has a negative charge (-1) equal to the positive charge of a proton (+1).

Neutrons are uncharged particles found within the nucleus.

Explanation:

The stethoscope is an acoustic instrument that amplifies sounds, it is used by doctors to perform a test known as auscultation, either on the chest or the abdomen. The hood or membrane is placed on top of the patient's body. This bell captures and amplifies the vibrations that arise from the sounds of the organs. This is possible thanks to the shape of the bell (concave) and the thinness of the membrane (to be able to copy and amplify the sounds). According to different studies, the noises that are heard on the surface of the thoracic wall are generated in the greater bronchi, mainly lobar and segmental. Noises reaching the periphery are low-frequency, since the lung serves as a filter for high-frequency sounds. The stethoscope amplifies the sounds heard in the area where it is placed. The vibrations can be auscultated with the stethoscope resting on the thorax, the abnormalities correspond to the increase or decrease in the quality of hearing,for example the increased perception of the auscultated voice can be classified as Broncophonia.

2) It results in the breakdown of large molecules into smaller molecules

Explanation:

A dehydration reaction or dehydration synthesis is a reaction that involves the loss of a water molecule as one of the products. As the name implies (de- remove, hydrate-water), water (H20) is released as chemical covalent bonds forms between the joining small molecules.

Small molecules called monomers are joined together to synthesize a much larger molecule called Polymer. Since it involves the joining or condensation of two small molecules, dehydration synthesis is also referred to as CONDENSATION reaction.

Dehydration synthesis builds up large molecules from small ones, hence, it is an endothermic process i.e. requires energy to occur. Hence, the untrue statement in the question is that dehydration synthesis results in the breakdown of large molecules into smaller molecules because it is the opposite (synthesis of large molecules from small ones).

It results in the breakdown of large molecules into smaller molecules is not

true regarding dehydration synthesis.

Dehydration synthesis is also known as a condensation reaction as it

involves the formation of a large molecule from two or more smaller

molecules through the formation of chemical bonds.

It requires energy and is characterized by the formation of water molecules

Answer:

Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group. The R group determines the characteristics (size, polarity, and pH) for each type of amino acid.

Explanation:

In order to identify an amino acid, there are several characteristics that can be used. One of the main characteristics is the presence of an amino group (-NH2) and a carboxyl group (-COOH) in the molecule.

This is a functional group containing a nitrogen atom, represented as -NH2. All amino acids have an amino group attached. This is another functional group present in amino acids, represented as -COOH.

Other key characteristics include the presence of a side chain (R group) that can be polar, nonpolar, or charged, and the ability to form peptide bonds with other amino acids.

Amino acids are the building blocks of proteins and are essential for many biological processes. There are 20 different amino acids that are commonly found in proteins, each with its own unique side chain and properties.

By understanding the characteristics of these amino acids, scientists can better understand the structure and function of proteins and how they contribute to the workings of the body.

It is actually the transfer of molecules between chloroplasts and mitochondria that allows a flow of energy from the sun through all living things.

Chloroplasts and mitochondria are two organelles found in cells. Chloroplasts are found in plant cells, while mitochondria are found in all eukaryotic cells. Chloroplasts are responsible for photosynthesis, the process by which plants convert light energy into chemical energy. Mitochondria are responsible for cellular respiration, the process by which cells use chemical energy to produce ATP, the cell's energy currency.

The transfer of molecules between chloroplasts and mitochondria allows a flow of energy from the sun through all living things. In photosynthesis, chloroplasts use light energy to convert carbon dioxide and water into glucose and oxygen. Glucose is then used by cells as a source of energy, and the oxygen is released into the atmosphere. In cellular respiration, mitochondria use glucose and oxygen to produce ATP. ATP is then used by cells to power their activities.

Answer:

New stars are able to form from hydrogen gas and dust clouds because the hydrogen gas and dust clouds allow for a new star's fuel.

Gravity allows for the hydrogen gas and dust clouds to condense into a star form. With more and more hydrogen gas and dust clouds combining, the pressure increases and the condensing becomes heavier and heavier. The pressure allows for fusion to start occurring.

Once hydrogen gas and dust clouds have finished condensing, the fusion will still be present. The fusion of hydrogen (fuel) into helium (product) allows to the star to emit light and heat.

Answer:

The process of gene flow

Explanation:

Gene flow refers to the transference of genetic variation from one population to another. High rates of gene flow are known to modify the allele frequencies and reduce genetic differences among groups. Gene flow limits the process of speciation by combining gene pools form different groups. In humans, for example, it has been shown that migration in the past decreased genetic variation among their populations, thereby leading to the homogenization of genotype frequencies among geographic groups. It is for that reason that in population genetics the concept of 'human races' is now often recognized as erroneous and inadequate.

Answer:

10.12 oz

Explanation:

Since Mrs. Sweet weighs outside the 100-220 pounds, she will receive a dosage of 2 ml/kg. Her weight is 330 pounds.

1 pound = 0.453592 kg

330 pounds = 330 x 0.453592 = 149.685 kg

2 mL of glucola is required for 1 kg of weight. Hence 149.685 kg would require;

                    2 x 149.685 = 299.37 mL

1 oz. of glucola is equivalent to 29.5735 mL. Hence 299.37 mL would be equivalent to,

                       299.37/29.5735 = 10.12 oz. of glucola

Lucy should therefore give Mrs. Sweet 10.12 ounces of glucola.

Answer:

b. Feedback response

Explanation:

Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.

Answer:

3. An even number of chromosomes are required for synapsis during prophase I and proper pairing during metaphase

Explanation:

Mules are hybrids of a cross between a female horse and a male donkey. Horses contain 64 chromosomes while donkeys contain 63 chromosomes in their somatic cells respectively. This means that they each produce 32 and 31 chromosomes respectively during meiosis. A mule, hence, contains 32+31= 63 chromosomes in their somatic cells.

This chromosome number in mules are uneven for meiosis to occur because meiotic division requires that an even number of homologous chromosomes pair together in a process called SYNAPSIS during prophase I of meiosis I. This is impossible in a mule because of the uneven number of chromosomes in its cells.

Also, during metaphase of meiosis, the homologous chromosomes need to be properly aligned at the equator for separation to occur. This is also impossible in a mule considering the number of chromosomes that don't add up.

Due to this reason of unevenness in the number of chromosomes present in a mule, meiosis will not occur and if meiosis (gamete formation) does not occur, reproduction cannot take place. Therefore, the mule is a sterile species i.e. cannot produce offsprings via sexual reproduction.
