Explanation:
in the diagram we don't know the value of X
but in the next figure we know how much the Forse is applied. so when describing a motion. we need to include the unit and the magnitude to underestimate there value
Answer:
B
Explanation:
It's NAD+ because if you look at the electron transport chain, NADH delivers its electron to protein 1 (which causes NADH to turn to NAD+) and eventually those electrons move through multiple proteins to finally be accepted by Oxygen. If there's isn't oxygen, NADH won't be able to deliver electrons since those electrons wont end up anywhere. Which means NADH won't be oxidized (lose electrons) to turn into NAD+. NAD+ is necessary in citric acid cycle since it is reduced to turn into NADH.
Eukaryotic cells posses a nucleus the purpose of the nucleus is it stores DNA which is the genetic material for the cell DNA acts as an instruction manual for the other organelles in the cell. While prokaryotic cells do not have a nucleus they still have dna but it’s floating around freely
