Answer:
526.12 μm³
Explanation:
Given that;
A typical human cell is approximately 10.00 μm in diameter &
enclosed by a membrane that is 8.000 nm thick.
What is the volume of the cell including the membrane?
First, let's determine the radius of the human cell=
= 
= 
= 5 μm
Now, the radius of the cell including the membrane
= 5 μm + 8.000 nm
= 5 μm + 0.008 μm
= 5.008 μm
The volume of the cell including the membrane is given by the formula:
![V_{cell]= \frac{4}{3} *\pi *(r_{cell})^3 um^3](https://tex.z-dn.net/?f=V_%7Bcell%5D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%28r_%7Bcell%7D%29%5E3%20um%5E3)
526.1160731 μm³
526.12 μm³
<span>D. Temperature and pH can affect how enzymes work.</span> The action of enzymes can be affected by many factors including temperature, pH and ionic strength. Optimum pH differs per enzyme. Enzymes can be destroyed by heat more than the allowed optimum temperature.
