So according to above explanation
<span>C. puncated equilibrium</span> , is the correct
answer
The incorrect statement is option (A) the innate defenses of the body apply strictly to external pathogens, while adaptive defenses apply strictly to internal pathogens.
Immunity can be classified into two types namely, the innate immunity and the adaptive immunity. Innate immunity is the first line of defense against the pathogens. It includes the physical and chemical barriers of the immune system along with the action of the phagocytizing cells called the macrophages. Whereas, the adaptive immunity is mediated by the cells of the immune system called the lymphocytes. The B lymphocytes produce antibodies and are responsible for humoral immunity. The T lymphocytes produce the cell mediated immunity with the production of the helper T cell, cytotoxic T cells and attack the pathogens. Innate immune response is comparatively a faster immune response which can be activated by any foreign substance entering the body. Both the defenses work on external and internal pathogens.
Answer;
-Organizing the mitotic spindle in cell division
Explanation;
-A centriole is an organelle that helps cells divide, or make copies of themselves. Centrioles are only found in animal cells. All centrioles are made of protein strands called microtubules. Centrioles are made of nine triplets of microtubules arranged in a cylinder.
-The main purpose of a centrosome is to organize microtubules and provide structure for the cell, as well as work to pull chromatids apart during cell division.
Producers would be the correct answer.
Producers get energy from the sun and use it for producing
The measurements indicated below that can involve a direction include Acceleration and Distance (Option A and C).
<h3>What do magnitude and direction mean?</h3>
Magnitude can be defined as a type of measurement based on a number or range value that does not involve orientation, while the direction is a magnitude that indicates orientation.
