In biochemical reactions, it is mostly triggered by enzymes. Enzymes are important components in the process that involves metabolism and digestive functions, further, most of these enzymes are proteins.Proteins are biological macromolecule and mostly composed of enzymes.<span> Proteins play a role in the physical make-up of a cell or acts as a cytoskeleton –maintains cell shape and figure. These proteins plays different roles and works with nucleic acids and other macromolecules in the cells including cell cycle, cell adhesion, immune response and cell indicators. </span>
Answer:
B. Layers that cut across the most other features are youngest.
Explanation:
Using the principles of cross-cutting relationships, you can determine the relative age of rocks found in the ground. The idea behind it is that the geologic feature which cuts another is the younger of the two features, and it had been around for 400 years. It's not very precise but it is good for determining relative age.
There are some reasons which could be mentioned:
1)Energy is lost as heat at each feeding level
2)Consumers who feed directly on plants have more energy for themselves than consumers feeding on other consumers. Indeed, energy again is lost in each level.
3)Feeding cattle is not productive, because energy must be transferred from plants to the cattle and then to people.
