As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.
Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.

The lymph modes is the small secondary lymphoid organs which cluster along lymphatic vessels.The lymph nodes are small bean shaped gland which are found throughout the body. They are part of lymphatic system which carries fluid (lymphatic fluids) ,nutrient and waste material between the body.
D because they have the same materials but different structure which mean different functions
Answer:it is a similar thing to natural selection, the ones less effected by it survive and adapt over time to survive the vaccine. However, google defines it this way, "The adaptive immune system, also known as the acquired immune system or, more rarely, as the specific immune system, is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth"
Explanation:
Answer: Only some of the organisms survive and reproduce.
Natural selection is a process of differential survival and reproduction in which organisms bearing favorable phenotypic traits survive in changing environmental conditions. Therefore, only some of the organisms survive and reproduce which have suitable phenotypic trait. For example a population of beetle bearing two colors red and green. The green colored beetles mimic the color of grass will remain undetected by birds and those with red color easily observed and detected by birds. Hence, only green beetles are favored for survival over red beetles.
