The correct answer will be A;
A) The number of protons in the nucleus does not equal the number of neutrons.
A=mass number:
Z=atomic number (= number of protons)
N=number of neutrons:
A=Z+N
If the number of protons in the nucleus is equal the number of neutrons , we would have an even mass number; because Z=N=x; then A=x+x=2x (this is always an even number) but 23 is an odd number, therefore the number of protons in the nucleus does not equal the number of neutrons.
Answer:
B.) II only
Explanation:
More land is needed for plants than combined beef to produce 100 grams of protein because plants produces very low amount of protein as compared to beef that produces large amount of protein. Beef is made up of protein so when we eat it, it provides large amount of protein while on the other hand, plant body is made up of other molecules and very little amount of proteins.

This is a difficult answer because the way you worded it but I believe I understand. The answer is chloroplast. They absorb light to help feed a plant cell.
