Which are examples of negative feedback? Select three options. a child whose thymus gland is building an immune system that gets stronger each day
when someone’s adrenal gland reacts to a scary movie by secreting hormones that make the heart beat quickly
when someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently
when someone’s pancreas hormone increases every time they eat, but decreases when they aren’t eating
when a person takes calcium supplements so a gland will stop secreting a hormone that pulls calcium from the bones

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
