Answer:


- The SA:V ratio of the cell that will exchange materials with its environment at the fastest rate is 5μm²/μm³
<u />
Explanation:
<u>1. Show the data properly:</u>
Cell A:
Surface area:

Volume:

Cell B:
Surface area:

Volume:

<u>2. Find the surface-to-volume ratio of each cell.</u>
Cell A:
SA: V

Cell B:
SA:V

<u />
<u>3. Compare</u>
The cell that will exchange materials with its environment at the fastest rate of diffusion is that with the greater SA:V ratio. That is cell A.
The reason is that a greater surface in relation to the volume the cell contain means that it has a bigger area to permit the exchange of the materials.
Answer:
The proton number is found in the periodic table of elements.
Explanation:
<em>The atomic number </em>is the number that defines each element in the periodic table. It accounts on the number of protons in a nucleus of an element, as well as the number of electrons. It is marked by the letter Z.
It should be distinguished from the mass number which is the total number of protons <em>and </em>neutrons inside a nucleus.
The legislative branch consists the Senate and the House of Representatives. Its role is to pass laws that are beneficial to the State. The Civil Rights Act had several versions and revisions. The legislative branch used the Fourteenth Amendment to pass the Civil Rights Act of 1875. This government branch also reconstructed the Civil Rights Act in the late 1960s.
