Answer:
Neutrophils represent the first line of defence in response to invading microbes, by phagocytosis of pathogens and/or release of antimicrobial factors contained in specialised granules.
Answer: A. environmental influences
A development in terms of biology is a gradual process of changes that occurs in an organism until the organism attains maturity or adulthood. Development can be physiological and mental development. Environmental influences are influences of nature on development. Some of the environmental influences are nutrition, altitude, temperature and climate. For example sunny weather conditions in a region can induce dark complexion in the habitants.
A cladogram is a type of graph that shows how closely related different types of organisms are in an evolutionary context. It resembles a tree, with various organisms being placed at the end of each branch. If two organisms have a close common branch, they are more closely related than those who have more distant branches. Since DNA, or corresponding protein sequences are more similar in closely related species, and more different in more distant species, a biologist can use those sequences to numerically determine how closely related three species are.
