Chlorophyll molecules are the most abundant pigments in plants that are responsible for collecting light for photosynthesis. Whi

ch of the following statements are true? The two main forms of chlorophyll are chlorophyll a and b. These molecules resemble the protoporphyrins in hemoglobin and myoglobin, except these contain Fe+2 rather than Mg+2. They require the presence of accessory pigments such as beta-carotene and lutein in order to function. They absorb light in the blue and red region of the visible spectrum, which is why they appear green.

Answer: Option A.

The two types of chlorophyll are chlorophyll A and B.

Explanation:

Chlorophyll is the green pigments present in chloroplast (organelles) that is found in plants which is used for photosynthesis by reacting with carbon dioxide and water to produce carbohydrates. The two types of chlorophyll are; chlorophyii A and chlorophyll B.

Chlorophyll A is the primary photosynthetic pigment that absorb energy from blue- violet light and orange red lights wavelengths.

Chlorophyll B is the accessory pigment to receive energy and transmit it to chlorophyll A. Chlorophyll B absorbs energy from green lights wavelengths.

algol [13]

Answer:

F1 Females  - all wild type

F1 Males  - all wild type

F2 Females  -  - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

  • Xᵛ⁺Xᵛ⁺ females with wild type eyes
  • Xᵛ⁺ Y males with wild type eyes
  • Xᵛ Xᵛ⁺ females with wild type eyes
  • Xᵛ Y males with vermilion eyes
