Answer:B. Their DNA molecules have different numbers of strands.

Explanation:that is chromosome that make them to differ in diploid numbers thus differ generally and appear differently

I disagree with the above answer. The answer should be D as the different nucleotide sequences would result in different proteins formed and synthesized that would eventually perform different functions and account the for the structural differences between the two species. While amount of DNA differ, it does not account for the vast differences observed.

Julia created a chart to summarize the three types of tectonic plate boundaries. What in her table needs to be correct?

Rzqust [24]

Answer:

Um, first of all this isn't biology it's geography.

Explanation:

But I guess I could help. I think that table C needs to be corrected because divergent plate boundaries are known to separate instead of colliding to form new crust but I could be mistaken so you have to double check. If I am correct please make me brainliest

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
