Answer:

A and B is correct.

Explanation:

Mutations are spontaneous variations to nucleotide sequences, therefore in two animals or two chromosomes they can not be identical by nature. Therefore, the introns interact with non-coding sequences and therefore their sequences are not established as consensus in nature and are therefore highly prone to mutations.

Hence both the statement are correct.

The chloroplasts of flowering land plants typically contain at least two photosynthetic pigments
SashulF [63]

Answer:

Chlorophyll A, and B.

Explanation:

Chlorophyll is known as the green pigment which is present in plants. Through the process of photosynthesis, It helps to convert solar light into useful energy. They have light absorption properties, so they are known as photoreceptors. Mainly two types of Chlorophyll are present in plants:

Chlorophyll A: It Is known as the primary photosynthetic pigment and has the ability to absorbs red, blue, and violet lights. Chlorophyll A is the location of the photochemical processes and can absorb light which is needed for the process of photosynthesis.

Chlorophyll B: It mainly helps to absorb blue light which is utilized to fill out the absorption of chlorophyll A it means it helps to supply additional light energy to chlorophyll A. It is known as the accessory pigment.

nikitadnepr [17]

Answer:

Meiosis and Genetic Variation.

Explanation:

When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.

When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.

In sexual reproduction, two gametes unite to produce an offspring. But which two of the millions of possible gametes will it be? This is likely to be a matter of chance. It is obviously another source of genetic variation in offspring. This is known as random fertilization.
