Answer:
The correct answer is - A. RY, rY, Ry, ry
Explanation:
Gametes are the sex cells or reproductive cells that are haploid in number. Gametes carry only one allele of each gene or chromosome in any organism. The male gamete called an egg or ovum whereas the male gamete called sperm or pollen.
In this case, the heterozygous plant has the genotype RrYy. In each of the gametes, there would one allele of each gene. The gametes get a dominant R and a dominant Y allele and a recessive r and a recessive y allele. Each produces 25% each of RY, Ry, rY, and ry.
The correct answer is: egg growth.
Follicle stimulating hormone (FSH) is gonadotrophic hormone produced by the pituitary gland with the function to regulate the growth and development of both the ovaries and testes.
FSH stimulates the growth and maturation of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation and increases oestradiol production.
The secretion of FSH is controlled by gonadotropin-releasing hormone (GnRH) released from hypothalamus.
<span>There are two physical differences
between Low pressure systems and </span>High pressure systems.
First, is the circulation surrounding
them.
Secondly, is the atmospheric motion
that they cause.
Low pressure systems circulate counter-clockwise. High pressure systems
circulate clockwise. These "motions" are the
building blocks in our atmosphere. They give us our weather.
A Low’s counter-clockwise circulation forces air upward (ultimately resulting in
condensation, cloud formation and ultimately precipitation). A High’s clockwise
circulation causes a sinking motion in the atmosphere, resulting in fair/clearer
and often sunnier skies.
Answer:
Cells divide so living things can grow. When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells.
Answer:
An adequate sample of a population for studies of natural selection should
be large enough to:
represent the genetic variation in the population
