Answer:

Because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same. Both genetics, as well as external factors, can play a role in the development of cancer.

The net primary production of a pine forest on a lava flow on Mount Fuji is about 165,000 kcal/m2/yr, and the plant respiration
IceJOKER [234]

Answer:

<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>

Explanation:

To answer this question, we need to know that  

  • gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
  • net primary productivity (NPP) = difference between GPP and respiration rate

So, to calculate GPP we need to sum NPP to Respiration rate. This if,

NPP = 165,000 kcal/m2/yr

R = 95,000 kcal/m2/yr

NPP = GPP – Respiration

Then,

GPP = NPP + R

GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr

GPP = 260,000 kcal/m2/yr

Which statement describes the relationship between the deer and plants on the food web? Tree is consumed by insect, which is con
True [87]

Answer: A.  Autotrophs supply food for the heterotrophs.

Therefore, because a deer consumes plants that means that autotrophs supply food for the heterotrophs. And by the way I did the exam myself and got this answer correct!
