Answer:
Arginine (Arg).
Explanation:
Lysine (Lys) is a hydrophobic amino acid that contains an α-amino group and an α-carboxyl acid group, and a side chain lysyl. It is a residue positively charged and has polar and hydrophilic properties, being thus similar to the Arg residue. Therefore, it is expected that the replacement of Lys by Arg should not have significant effects on the structure of the PEP carboxylase enzyme.
This type of substitution is named conservative because the replacement is made between amino acids with similar properties, thereby they have less impact on protein function and aren't so easily removed by natural selection compared to non-conservative substitutions.
Answer:
Secondary succession after a eruption
Explanation:
The answer is d because natural selection is the process in which organisms adapt to their environment and all of these answers fall into examples of natural selection
Answer:
(d) Molecules to areas of higher concentrations
Explanation:
The use of ATP to transport substances from a low concentration region to a high concentration region is called active transport because its against the concentration gradient.
And because it uses chemical energy from ATP is called active primary transport.
