I am an online student, this was a question on my quiz and I got it right.
You're welcome.
Also, to the member above me who also gave the correct answer, Good job!
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation.
Increasing the cell's volume would reduce the efficiency of the diffusion of materials through the plasma membrane into the cytoplasm of the cell.
On the other hand, increase the surface area and decreasing the volume oft the cell would increase the rate of diffusion across the plasma membrane.
The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
