Imagine that a man is scratched by his cat. A phagocyte near the scratch site recognizes and engulfs a bacterium. Shortly thereafter, more phagocytes arrive in the tissue surrounding the scratch. Why? The original phagocyte secretes antigens that attract the other phagocytes The original phagocyte secretes cytokines that attract other phagocytes The bacteria produces cytokines that attract other phagocytes The bacterium releases antigens that attract other phagocytes

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.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
