Answer:
A: stands for “adenosine triphosphate”
B: is an energy molecule
D: contains energy in phosphate bonds
Explanation:
ATP molecule is the energy currency of cells. It can be converted to Adenosine diphosphate (ADP) when it loses one phosphate molecule or Adenosine Monophosphate (AMP) when it loses another phosphate molecule. It is composed of the three phosphates, a sugar and an Adenine nitrogenous base.
D) chromosomes exchange genetic material in step 3
Explanation: the student claims that the cell division increases genetic variation, and D) is the only one which mentions exchanging genetic material/increasing variation
Answer:
Approximately 25 arteries would branch off
Explanation:
Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142
In case of the artery, pi x 0.2^2 = 0.126
So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021
Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.
