This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition

What is photorespiration? Why is it bad and why does it occur?
tekilochka [14]

Answer:

In cellular respiration it is a positive term, a process vital to life. But photorespiration is an entirely negative term because it represents a severe loss to the process of using light energy in photosynthetic organisms to fix carbon for subsequent carbohydrate synthesis.

•Address the letter to the editor of a local newspaper.
Julli [10]

The answer is; hydrothermal, geothermal, and wind

Hydrothermal, taped from the biggest river on the state contributes approximately 60% of the energy in the state. Geothermal is second,approximately 30% while wind power contributes approximately 10%.


The costs of the electricity in the state are relatively cheap compared with states whose main source of energy is hydrocarbon fuels.   Geothermal power is the cheapest (even though initial investment is prohibitive). Hydrothermal is slightly expensive than geothermal due to the maintenance required and also  is prone to fluctuations of the river regime. Winds are also cheap but initial investment if the wind farm is high.



Hydrothermal energy has the biggest environmental impact compared to the other two. Due to the walls of the dam on the river, migration of some aquatic species is impeded. The reduced flow of water (and sediments) downstream of the dam also impact these ecosystems. Geothermal and wind energy sources have a very minimal environmental impact on the environment .


The state could increase electronics with low power consumption (such as LED lights) in the market for availability to the population. This would be followed by a sensitization campaign on the ideal use of power in the household to conserve power when not in use.

A mutation that involves one or a few nucleotides is called
inysia [295]

A mutation that involves one or a few nucleotides is called

a) mutagen

b) inversion

c) point mutation

d) translocation

Answer:

c) point mutation

Explanation:

When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
