Biology

Marianna [84]3 years ago
7 0
I'm not sure what the answer choices are, exactly, but looking up the question I found several other questions with answers, so I'm guessing based on those the choices would be:
1) physical barrier within population
2) extensive gene flow
3) chromosomal changes within population.
Which, in this case, the answer would most likely be 3) chromosomal changes within population.

The baroreceptors in the carotid sinus and aortic arch are sensitive to which of the following? A. changes in arterial pressure
taurus [48]

Answer:

A. changes in arterial pressure

Explanation:

Baroreceptors are located in the aortic arch and carotid arteries. Baroreceptors are the sensory receptors that sense the stretching of arteries as a result of the pressure of the blood flowing through them.

For example, the stretch of the wall of the carotid sinus caused by the pressure of the blood in carotid arteries is sensed by baroreceptors present in the wall of carotid sinuses.

bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.
yawa3891 [41]

Answer:

A) P = P_0 e^{rt}

B) 19564

C) 5.5 or 6 hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

P = P_0 e^{rt}

Where ,

P represents the population after "t" hours

P_0 represents the initial population.

r represents the rate of growth of population

t represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778

Thus, the population of bacteria after 5 hours

P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P =  19564\\

C)

30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6

Travka [436]
It is true, because most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
