Answer:
The nervous system uses cell-communication by electrochemical signals that hormones, neurotransmitters or cytokines
Explanation:
Cell communication is vital to maintain internal environment thanks to homeostasis process which regulates the responses to internal and external stimulus. The functioning of cells depends on the electrochemical signals, these allows the communication and coordination among a group of cells of the tissue.
There are different type of loop-responses:
Negative Feedback Loops;
Reaction that causes a decrease in function, in response to some stimulus. The maintenance blood pressure, blood pH, oxygen/carbon dioxide balance, water balance (osmoregulation),calcium levels, among others are examples of negative feedback loops.
Positive Feedback Loops
Are involved in the amplification of the stimulus. D
Answer: TRUE.

In a sense, the discrimination against African Americans is related to economic stratification. In the 17th century colonial Virginia, the concept of race was adopted and used as a justification for social classification for groups of people. This was a result of a violent uprising known as Bacon's Rebellion in which lower class African and Europeans both who were denied land holdings in the Virginia frontier. The rebellion was so destructive that the Virginian governing body set in place strict segregation between Africans and Europeans in a way to prevent them from collectively joining forces again to create another violent uprising. Since then, those of African have gradually lost certain rights and liberties in comparison to their Caucasian counterparts, to the imminent point in which Africans were nearly all reduced to the role of slaves. Even after the abolition of slavery, those of African descent were continuously denied abilities to obtain better economic and financial assets by a southern states that were still upset of losing their right to own slaves. This is evident by sharecropping being used as a way to keep African Americans on estates to work off for their freedom, as well as terroristic tactics used by the Ku Klux Klan, as well as forms of institutional racism that barred African Americans from the same working establishments as White Americans. In various ways, economic stratification has been a tool for discriminating African Americans throughout American history.<span />

<span>What
is a step u can take toward committing to a career path?
Although letter B is not a WRONG answer, I think the more appropriate answer is
letter A. learn what type of education to pursue for your chosen field</span>
For example, I have no idea what course to
pursue but wanted something in the field of art. So I researched what courses
are available in this field. If I had gone with letter B. Talk to parents, they
would have told me to become a doctor or engineer, which is not bad in itself
except I have zero interest in becoming any of those professions.
