Answer:
The addition of a chromosome in an egg cell.
Explanation:
Mutation may be defined as sudden, heritable change in the DNA sequences. The mutation may be caused during the DNA replication or may be caused by the environmental factors.
The mutation that occurs in the gametic cells may pass down from parents to their offspring. The addition of an extra chromosome in egg cell will be inherited in the next generation.
Thus, the correct answer is option (C).
This Is Most Likely True.
So, Your. Answer Is A.
Blood cells because they keep the cells alive and reproduce
Answer: The correct answer is-
B. by mutating their DNA in response to environmental conditions to gain beneficial traits.
Antibiotic resistance in bacteria means the bacteria is not susceptible to the antibiotic that is the effectiveness of antibiotic against the bacteria is eliminated or reduced.
It occurs when bacteria undergoes mutation that is alteration in the genetic material ( for instance, in one mechanism of resistance, mutation changes the protein that was earlier target for the antibiotic).
Therefore, by mutating the DNA in response to environmental condition ( such as exposure to antibiotic in this condition), bacteria gains beneficial characters and become resistant.
Thus, option B) is the right answer.
In animals, the circulatory system performs a similar function because it transports vital nutrients around the body of the animal, just like how xylem and phloem transport water, minerals, and sugar to different parts of the plant.
