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.
<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 cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer.

please always check over answers and hope this helps!!!
The cell wall contains not only cellulose and protein, but other polysaccharides as well. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
KCl is a neutral product because KCl is formed from the acid base reaction of KOH and HCl. KOH is a strong base and HCl is a strong acid and when you put them together, you get a neutral product after a chemical reaction. The acid and the base cancel each other out to cause a neutral product.
