How does the size of a cell’s surface area change compared to its volume when the cell grows?

Answers

Answer:

Surface area does not increase after certain growth with the same pace as the volume increases.

Explanation:

The volume of cell increases rapidly as compared to its surface area when the cell grow in size and this is the reason due to which which its surface area to volume ration gets smaller  leads to reduction in surface diffusion. After a certain growth,the surface area does not increase as the material that forms the surface of the cell cannot increase further . Therefore at this stage the cell must divide and produce smaller cells which are able to accommodate favorable surface area/volume ratios

. Why are the effects of acidic deposition often felt in ar-eas far from where the primary pollutants are produced?

Answers

Answer:

Acid desposition is very harmful for the environment because it can easily combine with primary pollutants like carbon monoxide, particulate matter, sulfur oxide etc and form harmful substances.

Explanation:

  • Acid desposition means acid forming pollutants in the atmosphere that can easily combines with the primary pollutants which is emitted from car and energy power plants.
  • One of the major culprit is sulful dioxide which is released from car. Once they react with water, produce sulfuric acid and nitric acid. Their pH is extremely low thus they acts as acid.
  • These acidic desposition create hazards in aquatic body,wetlands,aquatic fishes,shell fishes,may cause nitrogen pollution and also cause damage in ecosystem.
  • This is the main reason that acidic desposition often felt in area far from pollutants so that it does't hamper the ecosystem.

Which are replicated during interphase?

Answers

Answer: The correct answer is-

DNA molecules or chromosmes are replicated during the interphase.

Interphase is first stage in the cell cycle. It is further divided into three phases that is-

G1 ( first growth phase, during which cell grows and syntheises essential proteins for replication),

S ( synthesis phase as chromosomes are replicated during this phase). This important before cell divides in the M phase.

G2 phase ( second growth phase). During this, further growth of cell takes place and it prepares for division in the next stage that is M phase.

Sense we have now found the gene that controls nitrogen uptake, do you think it would be a good idea to genetically modify crop plants to grow with less nitrogen? Why or why not?

Answers

It might not be a good idea as nitrogen may be needed by plants in several cellular processes and eliminating nitrogen uptake might severely impair these functions if there are no alternatives to these pathways
