Answer:
The original phagocyte secretes cytokines that attract other phagocytes
Explanation:
Before phagocytosis occurs and with the presence of an original phagocyte at the scratch site mostly a macrophage (also a phagocyte), chemical signals signals are given off to attract phagocytes to the scratch site.
These chemical signals may be cytokines that are given off by macrophages located in the tissue near the infection site etc. These cytokines produced can then stimulate the recruitment of phagocytes including the neutrophils and monocytes from the blood.
Answer;
- large-scale changes in chromosome structure
Explanation;
-Alterations to chromosome structure or changes in the number of copies of chromosomes in a cell.
-Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
