"an increase in predators" would likely lead to an increase in genetic variation in a population of squirrels, since the squirrels would have to adapt to the new threats.

Answer;
An increase in available food and and also decrease in predators would most likely increase the genetic variation in a population. 

Explanation; 
Genetic variation is essential for natural selection since the natural selection can only increase or decrease the frequency of alleles that already exist in the population. Genetic variation may be caused by mutations, and random mating between organisms. 
Increase in the available food also increases the genetic variation as organisms are able to interact freely and thus increases the chances of random mating.

Choose the term that best matches the description given. Treatments that destroy or decrease the growth of a microbe infection i

Answer: The correct option is D (Antimicrobials).

Explanation:

Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:

--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.

--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.

The antimicrobial drugs achieve their role usually through their different modes of action which includes:

--> cell wall inhibition

--> inhibition of cell membrane function

--> protein and nucleic acid synthesis inhibition.

Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.

How do the hormones of the pancreas maintain homeostasis?
faust18 [17]
Hormones glucagon and insulin are produced in the alpha and beta cells respectively in the Islet of Langerhan in the pancreas. They are involved in the negative feedback system of blood glucose regulation in homeostasis.

GLUCAGON: when there is a low blood glucose concentration, the pancreas detect this and alpha cells produce and release glucagon. Glucagon causes the cells of the body to absorb less glucose from the blood. It also inhibits the process of converting glucose into glycogen (glycogenesis) and cause gluconeogenesis (process of converting amino acids/proteins and lipids/fats into glucose) and glycogenolysis (conversion of glycogen to glucose). Finally, glucagon decreases the rate of respiration so less glucose is required.

INSULIN: when blood glucose is high, insulin is released. Insulin binds with cell surface receptors of cells and activates the enzymes attached to the receptor. The enzymes cause a conformational change in the structural proteins that surround glucose transport protein containing vesicles, causing them to move out of the way so the vesicles migrate up to the cell membrane and glucose transport proteins can fuse with it. Thus, more glucose can be taken in by cells. Insulin also cause glycogenesis (converting glucose into glycogen) and inhibits gluconeogenesis and glycogenolysis.

Basically insulin decreases blood glucose concentration (eg. after eating) and glucagon increases it (eg. skipping breakfast in the morning)
