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.
<u>Denaturation</u> is the <u>destruction of the protein's secondary and/or tertiary structures</u>. The <u>primary structure is not disrupted due to the tough peptide bonds</u> 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 <u>(FSH, LH)</u>, antibodies <u>(IgA, IgM),</u> enzymes <u>(lipase, amylase),</u> for storage/transport <u>(hemoglobin, ferritin)</u>, and locomotion <u>(actin, troponin).</u>
D) Their function depends on their three-dimensional shape.
Just like <u>hemoglobin</u>, it's <u>quaternary structure</u> can carry <u>4 molecules of iron</u> in one go. <u>Enzymes</u> are shaped accordingly to fit a<u> specific substrate</u> <em>(lock-and-key model)</em>

Answer:
The correct answer will be option-D.
Explanation:
In the given question doctor used the scientific method to understand and explain the natural phenomenon.
The scientific method involves various steps like making an observation followed by background research, predicting a hypothesis and performing tests to test the hypothesis. These steps have been performed by the doctor.
After these steps the doctor will analyse the result and reach to the conclusion. This would be followed by publishing the results in a scientific journal where it would be reviewed by the fellow scientists.
Therefore, the next step will be publishing the result and thus option-D is the correct answer.
The statement above is FALSE.
When a particular specie in an ecosystem is endangered, other species that interact with it will be negatively affected and the ecosystem may be throw out of balance. This is because all the components of the ecosystem depend on one another for survival.
