Answer: Adaptive radiation

Explanation:  Darwin's Finches are the best example of adaptive radiation. The Darwin's finches were originally not the fiches but these endemic species adapted specialized feeding behavior.

They were derived from a single ancestor that arrived to the island from South America. These birds had beaks of different sizes and shapes for the eating food.

Adaptive radiation is an evolutionary activity which creates several new species out of a single specie. Darwin embraces this philosophy that the finches evolve from an ancestral finch by adapting to the different environment.

4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
lyudmila [28]

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.

A gene exists in two alleles, which we will call B and b. The gene is 1123 bp in length, and the B and b alleles exhibit single
Hitman42 [59]

Answer:

The below options will complete the question

Select one:

a. Gap repair synthesis

b. Mismatch repair

c. Direct repair

d. Nucleotide excision repair

Our answer is surely A.

a. Gap repair synthesis

Explanation:

Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.

In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele

being digested away.

Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.

The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
