<u>Answer</u>:
C) They invade the body and can cause a humoral immune response.
This best explains the impact that pathogens in the environment might have on one's body.
<u>Explanation</u>:
Pathogens are the microorganisms that are found in the environment and have the tendency to cause diseases. The human body has various lines of defenses against the incoming pathogens, the Nonspecific responses keep the pathogens outside the body and these responses are common for all pathogens. If a pathogen manages to enter the body, then a series of specific responses are triggered which are focused on the type of pathogen.
The humoral response is a category of specific immunity and involves the substances found in body fluids. It particularly targets the newly invading pathogens. Hence, option C correctly describes the impact of pathogens on the body.
From the options given above, the correct option is D. A haploid cell is a cell that contains a single set of chromosomes only. A haploid cell can only undergo asexual reproduction. Asexual reproduction involves only one parent and the cell division usually occurs by mitosis. An organism that is reproducing asexually will transmit 50% of its gene to its offspring[s]. Thus, haploid cells reproduce asexually through mitosis only.
Answer:
As insect nymphs grow larger, their exoskeleton becomes too tight and they must replace it. Once a nymph outgrows its exoskeleton it will go through a process called molting, in which it leaves the old “skin” or exoskeleton behind. The new “skin” will harden and become the new exoskeleton
Explanation:
It takes the Earth (approximately) 364.25 days to revolve around the sun. That's why we have leap days.
Hope that helps!
