Answer:

The correct answer is option a.) "oyster".

Explanation:

Oysters are aquatic organisms known for being the main producers of pearls, beautiful round jewels that are valuable fashion items. Oysters produce pearls through a biological process, which final aim is to protect the oyster from foreign substances. The pearls are formed as a result of the oyster response to irritation,  which is by covering the uninvited visitor with layers of nacre.

What is the significance of a recombinant plasmid?
drek231 [11]

Answer:

recombinant DNA

A strand of DNA formed by splicing DNA from 2 different organisms is called recombinant DNA

Explanation:

Using the techniques of recombinant DNA technology, certain enzymes known as restriction enzymes capable of cleaving double stranded DNA in the plasmid of bacteria genomes (other organisms like eukaryotes can also be used) are used to obtain specific sequences of DNA bearing desirable traits in the both organisms.

Once the two DNA fragments have been obtained, another enzyme known as DNA ligase is used to seal the point of splicing, thereby constructing a single DNA from the two organisms.

This single DNA is known as Recombinant DNA

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
