The cytochrome c in both horses and pigeons differs from the human protein at 12 locations. Based on this data, you might infer
yuradex [85]

Answer:

Cytochrome c is an enzyme found in bacteria, fungi, plants and animals. Here it is given that the human amino acid sequence for cytochrome c differs at 12 locations from the sequence in horses and pigeons. This information might be useful for inferring in preliminary stages that horses and pigeons are closely related to each other since they both show similar amount of difference from humans.

However, this hypothesis is being made with respect to the the comparison between "humans and horses" and "humans and pigeons". To further test this hypothesis pigeons and horses should be directly compared to each other without the use of a third species like humans. Hence, the sequence for cytochrome c in horse and pigeon should be compared with each other rather than comparing to humans.

Advocard [28]

Answer:

It depends...

Explanation:

Group 1 is trying to obtain energy, so as we know that lipids and carbohydrates are the basic source of energy because of their storage properties and generation of ATP during glycolysis and lipid metabolism in our body.

Group 2  is trying to obtain nutrients so to rebuild their molecules and body cells they must take enough quantities of vitamins/minerals for that. Proteins are also crucial to for rebuilding lipo-proteins in cell wall of cell amke them crucial for them. They also play an important role in muscle cell repair and replacement due to their primary composition of actin and myosin filaments.
