4 0

Answer:

3.14 residues

Explanation:

This kind of sheets has the particularity that the distance between adjacent residues is 3.5 Angstroms. Furthermore, there are two residues per cycle.

Hence, we can calculate easily the number of residues in a segment, by using the expression:

Nr = (256 Å) / (3.5 Å/residue) = 3.14 residues

I hope this is useful for you

primary, second-level, third level, fourth level, and fifth-degree of consumers are straightforwardly or by implication rely upon producers as they structure a significant food hotspot for creatures that feed by grazing. Models incorporate snails, imps, and corals. These consumers thusly will be eaten by different creatures, for example, ocean stars. At the head of the food web, there are bigger consumers, for example, fish, penguins, and seals. energy moves from producers to the consumers and there is a large part of the energy loss during the process only 10% of energy gets to the subsequent trophic level.
