DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.
Mutation (A)
Answer:
Option (2).
Explanation:
Ecological succession is the change in the ecological community of the species with respect to time. Two types of the succession are secondary succession and primary succession.
The ecological succession includes various transitional stages before reaching to the climax community. The simple species acquires first and then the climax species is reached at the end of the succession. Different changes are involved in the formation of climax community.
Thus, the correct answer is option (2).

its temperature because it's the best answer
Answer:
1/4
Explanation:
Let the earlobe allele be represented by A. since the attached earlobe is the recessive trait, the genotype would be aa while the free earlobe would be AA. The heterozygous condition would be Aa.
Two individuals heterozygous for free earlobes mated:
Aa x Aa
AA Aa Aa aa
AA and Aa = Free earlobe = 3/4
aa = attached earlobe = 1/4
<em>Hence, the probability of the couple having a child with an attached earlobe is </em><em>1/4.</em>
