The correct answer is option A, that is, Phylum Porifera.
The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.
They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.
I would say by making sure they raise them as healthy as possible and making sure they get vaccinated
The chemical processes that occur within a cell are affected by many factors. Optimum cell function will not occur due to the following factors: 1. These chemical processes are very sensitive to the temperature and the pH of the cell. If the cell's temperature is either too high or too low, the cell cannot function efficiently. The same can be said for a cell's pH. Enzymes are most active during a limited pH range. If the pH moves outside of this range, the cell's enzymes cannot function efficiently.
2. Cofactors and Coenzymes. Many enzymes and cell functions require additional factors and enzymes to function efficiently. If the required enzymes are not present in the cell, the cell cannot function properly.
Answer: Predation and herbivore
Explanation: density-dependent limiting factor where relative population sizes of consumers and their food control one another’s population size
