B, because of the dry climates, they need to retain as much water as they possibly can.
Amino acids- proteins
Glucose- carbohydrates
Triglycerides- fats
The genotypes would be 50% Bb and 50% bb
The phenotypes would be 50% brown and 50% white. Hope this helps :)
Explanation: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
