Answer:

The correct answer is option A - increased heart size.

Explanation:

Cardiovascular endurance activities or cardio-respiratory exercise can improve body ability by using large muscles like respiratory apparatus. Long term effect of cardio-respiratory exercise helps the hear and lungs to increase the supply of the oxygen and nutrients to the muscles for better function. These exercises help in increasing heart size by practicing moderate to high intensity for a long time.

Thus, the correct answer is option A. increased heart size.

I would say the food availability for gray squirrels will be affected because we do not know their diet. It also say that the red squirrels and the black squirrels have the same diets meaning less food on the Island for the grey squirrel( depending on what he eats. )

IgorC [24]

Answer:

See the answer below

Explanation:

Recall that: <em>Water potential = pressure potential + solute potential</em>

Since the system is an open one;

<em>Water potential = solute potential = -iCRT</em>

i = number of particles the molecle will make in water (1)

C = molar concentration

R = Pressure constant = 0.0831 liter bar/mole K

T = temperature in kelvin = 22 + 273 = 295 K

To calculate water potential on side A:

C = 1 M

Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars

For side B:

C = 2 M

Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars

b.

<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>
