A) a temperature is regulated by the body: so, not.

b) - rather not, most likely cholesterol level would be low

c) this is rather intedependent - a person can be active even without a fat diet.

d) I think this is the best answer. Metabolism is the exchange of energy in food into the energy that people use.

The correct answer is option D, that is, metabolism.

Metabolism is a term used to signify mainly towards the dissociation of food and its succeeding conversion into energy required by an individual's body. It is something, which comprises both anabolism and catabolism that are the buildup and breakdown of components.

The procedure by which the body transforms what one eats into energy is known as metabolism. At the time of this complex biochemical phenomenon, the calories in beverages and food are amalgamated with oxygen to discharge the energy one requires to work. Therefore, a person having a high amount of energy will have a high metabolism.

Look at the population pyramid. What conclusion can you draw from it?

balu736 [363]

c. Birth rates are high

Explanation:

A wide base in the population pyramid shows that there is a large population of young people with high fertility rate or birth rate and high death rate.

From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.

This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.

Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.

The graph shows the changing levels of hormones during menstruation and ovulation. What is the general trend for hormones after

rjkz [21]

The general trend for hormones after ovulation as an individual when it approaches menstruation is that hormone levels generally rise. This increase levels of estrogen and progesterone would cause a negative feedback to the hypothalamus and the pituitary, which would result in the decline of the FSH and LH. BTW: Not to be TMI but i started mine and there is nothing to be scared of.

Which of the following does NOT characterize proteins?

8090 [49]

Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)

What are some functions of protein

Sever21 [200]

Proteins also have structural or mechanical functions, such as actin and myosin in muscle and the proteins in the cytoskeleton, which form a system of scaffolding that maintains cell shape. Other proteins are important in cell signaling, immune responses, cell adhesion, and the cell cycle. hope that helped
