Answer: Paracrine
Explanation:
Paracrine signaling is a form of cell signaling in which a cell produces a signal that induces changes in nearby cells, altering the behavior or differentiation of those cells. Molecules known as paracrine factors diffuse over relatively short distances (local action), unlike endocrine factors (hormones that travel considerable distances over the circulatory system), juxtacrine interactions, and autocrine signaling.
<u>Cells that produce paracrine factors secrete them into their immediate extracellular environment. </u>These factors then travel to nearby cells where the gradient of the factor received determines the outcome. However, the exact distance a paracrine factor can travel is not known with certainty.

In the case of infection, cells of the innate immune system secrete different cytokines into their immediate extracellular environment that attract other immune system cells such as neutrophils and lymphocytes, to fight the infection.
Answer:
human used artificial selection to develop new organisms with desirable characteristics. Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits
