True.
After forming a hypothesis, or an explanation that would be experimented on, you would be <em>testing</em> it to see if it gives the results you were looking for.

The types of amino acid r groups will line the channel protein interior would be non-polar.
On the interior side of the system, there are non-polar amino acids that can form bonds with the hydrophobic tails of phospholipids inside cell membrane structures. By using the phenomenon of passive diffusion, they perform the fundamental task of moving materials across the membrane. The amino acid glycine contains an R group, as is the case. Valine, methionine, and alanine are a few of the non-polar amino acids, as are others.
Amino groups are more prevalent than carboxylic groups in polar amino acids with a positive charge. A more basic amino acid then results. On the "R" group of these amino acids, there is a positive charge. Lysine, arginine, and histidine are some examples of compounds that fall under this category.

The number of valence electrons define how the elements combine. For example, if element A has 3 valence electrons and element B has 5, they would share so that both element satisfies the octet rule.
Answer:
D
Explanation:
A and B are wrong because environmental impacts can't change the amount of chromosomes an animal has. D is a better answer than c because genetic variation happens within a population rather than an individual.
