1. C) Both parents contributed a recessive allele
The offspring is homozygous for the recessive allele, which means it has two copies of it. Because each parent contributes one copy of the gene, this means that both parents contributed the recessive allele.
2. D) The offspring can be tall or short
The first cross between TT and tt will yield an F1 generation with the genotype Tt. When this generation is self-pollinated, the cross may result in the following genotypes:
TT, Tt, tt
Which means that the offspring can be tall or short.
Answer:
Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.
Explanation:
The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
Answer:
out of
into
Explanation:
As pressure exerts force, Hydrostatic pressure is a type of force that occurs in fluid e.g (interstitial fluids) on the walls of the capillary. The helps to carry fluid-like materials out of the tissue capillary. There are quite bunch of relative factors affecting the hydrostatic pressure which include; the liquid density and distance beneath the liquid surface,force of gravity.
On the other hand, The protein osmotic pressure difference between capillary fluid and interstitial fluid normally favors movement of fluid into a tissue capillary. This protein substances consist of albumin, plasma protein etc. From our knowledge of osmosis as well, we knew it is the movement of substances through a semi-permeable membrane from the region of higher concentration to a lower concentration. Therefore the protein osmotic pressure bring about movement of fluid like substances into the tissue capillary.
Answer:
Hormone levels generally decrease.
Explanation:
<em>The graph showed that hormone levels after ovulation generally decrease.</em>
The menstrual cycle of women generally have 3 phases which include:
- <em>The follicular phase</em>
- <em>The ovulatory phase</em>
- <em>The luteal phase</em>
The follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.
The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.
The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.
