In peas, yellow seed color (Y) is dominant to green seed color (y). A homozygous green pea plant is crossed with a heterozygous yellow pea plant. What is the predicted phenotypic ratio of the offspring

Answers

Answer 1

Answer:

Answer:

2: 2 or 1:1

Explanation:

It is given that the yellow seed color is dominant over green seed color. The genotype of homozygous green pea plant and heterozygous yellow pea plants are “yy” and “Yy” respectively.

The following punnet table represents the cross between “yy” and “Yy”

y y

Y Yy Yy

y yy yy

The genotypic ration is 2Yy :2yy

Yy represents heterozygous yellow pea plant

yy represents homozygous green pea plant

yellow pea plant : green pea plant is equal to 2: 2 or 1:1

Answer 2

Answer: Each offspring will receive one allele from each parent, so the cross will be Yy with yy, resulting in four possible offspring: Yy, Yy, yy, and yy. Since Y is dominant to y, there will be two yellow for every four offspring or the ratio of 1/2 (Look up Punnet squares to understand this concept better)

Coordinate the immune system response by activating effector cells Memory B and T cells Helper T cells B cells Cytotoxic T cells

Answers

Answer:

Helper T cells

Explanation:

This is because it is a type of adaptive immune system that stimulate B cells, microphages and cytoxic T cells. Helper T cells are used in different adaptive immune responses. They help to activate B cells so as to produce antibodies and also help macrophages to destroy ingested microbes. they also help activate cytotoxic T cells which will inturn kill infected target cells.

What flower has an ugly bud but a beautiful blossom?

Answers

Explanation:

Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.

Species richness is the number of different trophic levels found in a certain region or ecosystem. 5) True 6) False

Answers

Answer:

6) False

Explanation:

No, it's not true, because species richness refers to the total number of species present within a particular community or ecosystem, regardless of their trophic level. Trophic level is a measure of an organism's position in its food web or nutrient cycle, and it is not directly related to species richness.
