Which cells migrate through the body, increase markedly in number whenever tissue damage occurs, and may develop into cells responsible for the production of antibodies?

"Lymphocytes" cells migrate through the body, increase markedly in number whenever tissue damage occurs, and may develop into cells responsible for the production of antibodies

Explanation:

A lymphocyte in the immune system of a vertebrate is among the subgroups of WBC (white blood cells). Lymphocytes is the umbrella name for:

Inside the bone marrow mammalian stem cells distinguish into different kinds in blood cells. That phenomenon is known as haematopoiesis. Throughout this system, all lymphocytes derive from a specific lymphoid progenitor before distinguishing from their different types of lymphocytes.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
