Kristen cut her hand on a piece of glass. As the blood clots, how do white blood cells prevent bacteria on the glass from infecting her blood.

Answers

Answer 1
Answer: They destroy pathogens that enter the wound. This obliteration of any pathogens is called phagocytosis. A white platelet ingesting infection creating microorganisms. White platelets can: ingest pathogens and devastate them. deliver antibodies to demolish specific pathogens.
Answer 2
Answer: White blood cells prevents from infection. They aggregate at the site of the cut, forming pus. Netrophils, a type of white blood cells act by englufing the pathogens, and destroying them. Monosytes WBCs ingests the damaged cells, thereby preventing their chances of being infected.

describe the results if you do an experiment to determine the physical properties of tyrosinase. if you run gel filtration and SDS-PAGE, what results do you see

Answers

Gel filtration and SDS-PAGE could be used for determining a molecular weight of proteins, such as tyrosinase. In both methods, molecules are separated based on their size. Gel filtration measures the molecular weight of native proteins and SDS-PAGE measures the molecular weight of denaturated proteins. 

As a result of meiosis, a gamete receives 1) a double set of the parent's chromosomes 2) two double sets of the parent's chromosomes 3) a single set of the parent's chromosomes 4) a different set from the parent's chromosomes

Answers

4) A different set from the parent's chromosomes since meiosis forms gametes, the recombination will create a new set of chromosomes.

Answer:

fossil fules

Explanation:

to determine the growth rate of a population, the number of births and deaths are factor in the equation. what other factors are put into the growth rate equation?

Answers

Answer:

The time that passes from one point to another

Explanation:

The growth rate equation is measure with the inital population, the population that increases (births) or decreases (deaths) in a certain time

P = Po x e(rt)

Where P = Total population over a certain time

Po = Starting population

e = Euler number ( 2.7128)

r= % growth rate

t= time in hours or years
Immigration into a population is also another factor that contributes to the growth rate of a population

In which ways does the body respond when its temperature is too high?

Answers

Vasodilation , when your body is to hot. Blood capillaries dilate and increase their diameter. More blood flows near the body surface. Excess heat in the body is lost through the conduction and radiation to the environment. Your arm hair also rises. 
The body can respond by :nose bleeds heat flashes passing out sweating.
