Answer:

Photosynthesis consists of two parts. The first requires sunlight and the second does not. The Calvin cycle is also called the dark reactions or light-independent reactions because it's the part that doesn't need energy from the sun to happen. The Calvin cycle takes place within the stroma of the chloroplast.

Write a short description of the life cycle of a flowering plan<br><br>

sammy [17]

Answer:

Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) f

lord [1]

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White
