11. A. Ovulation.
12. Semen.
13.The fluid--to some degree--helps protect the sperm from the acidic environment of a woman's vagina, which could otherwise damage and kill said sperm.
14. During the menstrual cycle, the endometrium grows to a thick, blood vessel-rich tissue lining, representing an optimal environment for the implantation of a blastocyst upon its arrival in the uterus; the body also begins to prepare for ovulation again.
15. Both the testes and the ovaries produces entities needed for the process of reproduction. But while the ovaries create eggs, the testes create sperms.
16. On the 7th day; on the 21th day.
17. C. The amniotic sac.
18. The umbilical cord.
19. The germinal stage, the embryonic stage, and the fetal stage.
20. two eggs; a single egg.
21. Since the pituitary gland produces hormones that stimulating all the other hormone-producing glands to produce their own hormones, that tumor could potentially causes the body to function incorrectly: For example, the body could not produces the required hormones needed for the body to start producing sperms/eggs, preventing the person's ability to reproduce overall.
Answer: It enables them to cover more of the visible light spectrum and therefore be able to harvest more light energy.
<span>Pigments can be defined as the molecule that
absorb specific wavelength of light or they are substances produced by living
organisms that obtain color from selective color absorption. Thus, the function of pigment in plant is photosynthesis
and they use green pigment chlorophyll with other pigments such as yellow and red
pigment which are being used to captures much light energy as possible.
However, plant gain from having much more than one pigment because it enables
them </span>to cover more of the
visible light spectrum and therefore be able to harvest more light energy.
<span>That's odd. Well, contaminated amylase would give you false positives; any experiment that requires it would potentially give erroneous results then? Without much more to go off of, I guess you could definitely say 2 and 4, though apart from that I guess you can't really be too sure. </span>
Large, permanent caves like those on the Sandy only form when a glacier is thin and the weight of the ice no longer squeezes the caves shut, allowing warm air to flow into the glacier. McGregor and Cartaya have drawn on years of experience mountaineering and caving to safely explore the caves in the Sandy Glacier.
Answer:
a.) It causes prolonged activation of adenylyl cyclase which leads to increased levels of Cyclic adenosine monophosphate(cAMP).
b.) In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
C.) Cholera can effectively be treated through the use of antibiotics and intravenous fluid replacement therapy.
Explanation:
Vibrio cholerae is a gram negative rigid curved bacillus that are actively ( vigorously) motion by a polar flagellation. The name vibrio is derived from the characteristic vibration movement of the organism when viewed under a microscope. This bacteria is capable of producing toxins called cholera toxin, which it uses as a virulent factor. It is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea.
Cyclic adenosine monophosphate(cAMP) which is called a second messenger because it is not a hormone that can directly institute an intracellular change, instead, it serves as a second messenger to cause an effect.In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
In the effect of cholera toxin on the cAMP in the intestinal cells, Cholera toxin increases the fluid loss. The binding of the toxin to the intestinal cells causes a large increase in the level of cAMP in the cells by inhibiting the conversion of GTP bound to Ga to GDP. So adenyl cyclase is not turned off and diarrhea results.
The possible treatment is through the use of antibiotics and intravenous fluid replacement therapy. Prompt and adequate replacement of lost fluid and electrolyte through oral administration and supplemented with intravenous administration of fluids highly suggested for treatment of cholera. Antibiotics is equally used for treatment only when the cholera strain has been confirmed sensitive to it through culture.
