They developed to be protected by the hard shell from parasites and ther predators.
Recombination or crossing over occurs during prophase i. homologue chromosomes- 1 inherited from each parent pair along their lengths gene by gene. Independent Assortment is the process where the chromosomes move randomly to seperate poles during meiosis

Answer:
The correct answer is - D. The initiation of a signaling mechanism that leads to the breakdown of glycogen into glucose that can then serve as the fuel for ATP production.
Explanation:
In challenging or dangerous conditions, the body releases a hormone called Epinephering which is a fight or flight hormone that provides a high amount of energy for the particular action.
Epinephrine hormone binds to beta-adrenergic receptors present on muscles and responsible for the rapid conversion of glycogen to glucose-1-phosphate. The glucose results in condition to rapid synthesis of ATP in muscles and thus helps in muscle actions.
