The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.

Explain negative feedback and its role?
_ It's the major physiological response to stimuli._ Always opposes the stimulusFor ex: Body temp. at 37oCor Blood sugar at 100 mg/dLor Heart rate at 70BPM
Explain why crystal violet would not be useful in the negative stain technique?
Negative staining techniques are designed to stain everything BUT the bacterial cells. This allows us to see the cells unstained and helps us observe their morphology (how the cells are shaped and how they group together). The cells have an overall negative charge on their surface, so they naturally attract positive charges. Crystal Violet carries a positive charge, so it would adhere to the surfaces of the cells thus staining the cells (which is not what you want in a negative stain!)
Explain how do feedback loops allow the body to maintain homeostasis?
They work a bit like a thermostat that keeps a constant temperature in a house. Negative feedback loops work through receptors, which sense a change such as in blood pressure. Signals are then sent to the control centres, usually in the brain, which then give instructions to the effectors - mechanisms which then regulate conditions such as blood pressure and bring it back to normal
How would you describe the gram stain?
Describe the Gram stain technique and the effect on Gram-positive and Gram-negative bacteria after each step. Be very specific about what is happening at each step and why it happens. (hint: be sure to fully explain your answer and not just list the steps)
Explain how your body temperature is an example of homeostasis?
just cuz
Explain would the formation of a goiter be positive or negative feedback?
Negative.
What are the advantages and disadvantages of supplier feedback?
Supplier feedback is positive when can explain why they enjoy the products a person is supplying. However, the feedback may be negative if the comment is harsh and is not helpful to bettering the supplier.
How do you explain how a negative times a positive makes a negative?
+*-=-. Example. 3*-3=-9.
Explain current shunt negative feedback amplifier?
describe current-shunt negative feedback as applied to operational amplifiers, including derivations of the gain relation for each type of negative feedback.
When a negative number is subtracted from a positive number a positive a negative number or a zero explain and give an example?
LOVE to HATE = Hate (Negative)LOVE to LOVE = Love (Positive)HATE to HATE = Hate (Negative)HATE to LOVE = Hate (Negative)HATE is a NEGATIVE numberLOVE is a POSITIVE number
Explain in your own words how we add numbers with different signs?
Positive plus positive equals positive. Negative plus negative equals negative. Positive greater than negative equals positive. Negative greater than positive equals negative.

Why is it impossible to get a negative answer when you square any number?
V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other. For example- -2 x -2=4 ============================ (a second answer.) Every real number is either negative, positive or zero. When you square a number, you multiply it by itself, so if you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative. ( It is harder to explain why a negative times a negative is positive.)
Give an example of a relation that is NOT a function and explain why it is not a function?
y² = x --> y = ±√x Because there are *two* square roots for any positive number (positive and negative) this will not be a function.
What does it mean for a negative to be decreased by a negative?
It becomes less negative To explain. Lets take a negative, eg -5. If we decrease it by 1, it becomes -6 (where 1 is positive) Thus if we decrease it by -1, it becomes -4 (as the -1 is negative) Note that the final number could be positive, For example, if you decrease -5 by -6, you get +1
Will a negative number to the fifth power be a positive or a negative value explain?
Negative, because 5 is an odd number
Explain why the square root of 64 has a positive and a negative value?
That simply means that there is both a positive and a negative number which, when squared, gives you 64.
