I think it is the first one (or the last one, i am not sure I understand the statements), but the point is that all species have the same gene code for the same proteins and amino acides, for example the aminoacid Cytosine is encoded the same in all species
Answer:
Tertiary structure
Explanation:
Tertiary structure can be described as the overall three-dimensional structure of the protein. Interactions between amino acid side chains (R-groups of amino acids) in protein determine its tertiary structure. These interactions play an important role in stabilizing 3-D protein structure and they involve: ionic bonds, hydrogen bonds, van der Waals interactions, covalent bonds, and hydrophobic interactions.
The answer is D! birds have to migrate for winter to find an abundance of food! they learned this over time making it a learned adaptation

However, an example of a cam plant is a cactus. They have CO2 -carbon dioxide- to produce acids. It stores the CO2 at night so it can be used during the day because cam plants are in extreme hot conditions. They release it during the day and it's formed in the Calvin cycle during photosynthesis to make glucose.
