They play an important role in the control system by sensing defects that occur during essential processes such as DNA replication or chromosome segregation, and inducing a cell cycle arrest in response until the defects are repaired.
Answer:
The scale is same.
Explanation:
The scale of nuclear fusion reaction on earth is the same as compared to fusion reactions that is happening in the sun because both reactions produces the same product i. e. energy and heat etc and both are occurring naturally. Due to large size of the sun, huge number of nuclear fusion reactions occur ac compared to the earth which is smaller in size so the scale of both nuclear fusion reactions are the same but vary in numbers.
To preserve and keep them fresh
Chemicals produced by bacteria that limit the growth of other bacteria are called antibiotics.
Their reproductive isolation from each other is complete: False
They are unable to produce hybrid offspring upon interbreeding: True
They shared a common ancestor recently in evolutionary time: False
Explanation:
A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.
This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.
