<span>Think of each amino acid like a different letter, there are only 26 letters but yet millions of words, it works the same sort of way. </span>
D because if the species was to be removed from an ecosystem, everything that needed that species as food, or the species ould have to adapt to the foods available in the new ecosystem they live in. Hope I helped, and let me know if you are still not 100% sure about the answer, and I'll try to clarify what I said.
Answer:
There are two types of cell, prokaryotic (bacteria) and eukaryotic (animal, plant, fungi and protoctista (unicellular organisms)). Prokaryotes have no nucleolus – the DNA is in the cytoplasm, and it can from small circular strands of DNA called plasmids. Eukaryotic cells all have their DNA enclosed in a nucleus.

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

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:
Yes
Explanation:
Of the many functions of protein in your body, one of its most critical is supporting your immune system. The immune response protects you against harmful microorganisms, including viruses and bacteria, as well as foreign substances that might attack your defenses, such as a thorn or flames from a fire.
