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:
Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase. Also, mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells.
Explanation:
If both of those sexual partners are faithful to each other, and only have sexual relations with one another, then there isn't a high probability that either of them is going to get HIV. If they want to be sure, they should use protection, such as condoms, to prevent getting HIV through body fluids. And they should always be honest with each other in case one of them has that disease.
Answer:
Recent research examined clinical applications using silk because of its ability to promote adhesion and proliferation of various cells including keratinocytes and fibroblasts[12,13]. In this study, we found silk dressing materials effective as burn dressing.
