Answer:
The correct answer is option 3. "secondary structure".
Explanation:
The secondary structure of polypeptide and proteins refers to the second order of folding, including common structures such as beta sheets, alpha helix, as well as turns and loops. The hydrogen bonds between the oxygen and nitrogen atoms of the peptide bonds are crucial to secondary structures, as these hydrogen bonds form and stabilize the aforementioned common structures.
Well it really depends on what kind of change there is. For this I'll use a drought as an example. If a drought occurs in an area the plant life and vegetation will start to die off in that area. From there, primary consumers would run out of food. then secondary consumers, and so forth and so on. it'd be like putting a cow in a field of dirt with no food and a large bucket of water. Eventually the cow will die of starvation. Now apply this to all of the animals in that ecosystem.
Answer:
The correct answer is option D) "a quaternary protein with four polypeptides".
Explanation:
Hemoglobin is a quaternary protein with four polypeptides. Hemoglobin is comprised of four polypeptides, two alpha chains with 141 amino acid residues and two beta chains with 146 amino acids residues. Hemoglobin is classified as a quaternary protein, because it reaches a quaternary structure when the different polypeptides are attached to each other.
