Unlike T lymphocytes, B lymphocytes

Answers

Answer 1
Answer: Unlike T lymphocytes, B lymphocytes arise from the bone marrow Bursa of Fabricus (in fowl) and gut-associated lymphoid tissue (Peyer's Patches); they are the major constituents of the humoral immunity or antibody-mediated immune system; they defend against viruses and bacteria that enter the blood and lymph; they are formed by the division of plasma cells; and plasma cells do not have inhibitory effect on the immune system.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and flagellated male gametes from the same gametophyte, and it releases spores into the environment. Which of the following is the best conclusion about the life cycle of this plant? (2 points)The plant is a gymnosperm, and the gametophyte is its dominant phase.
The plant is an angiosperm, and the gametophyte is its dominant phase.
The plant is a moss, and the sporophyte is its dominant phase.
The plant is a fern, and sporophyte is its dominant phase.

Answers

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.

Answer:

The plant is a fern, and sporophyte is its dominant phase.

In a dihybrid cross, round (RR), yellow (YY) seeds were crossed with wrinkled (rr), green (yy) seeds. What were the phenotypes of the F1 generation?

Answers

The answer is


Let's first represent alleles:
R - a dominant allele for round seeds,
r - a recessive allele for wrinkled seeds,
Y - a dominant allele for yellow seeds,
y - a recessive allele for green seeds.

The cross will look like this              RRYY     x    rryy
So, all of the offspring will be heterozygotes (RrYy) with round seeds (Rr), yellow seeds (Yy).
