Answer:
Explanation:
1)Pfr/Pr
2) Pr
3)far-red
Explanation:
The leaves at the top of a tree’s canopy are exposed to direct sunlight during the day, and their phytochromes will occur in a high *Pfr/Pr* ratio. Meanwhile, the leaves of the same tree at the bottom of the canopy are highly shaded during the day and will likely have a higher proportion of the * ( PHYTOCHROME )Pr *;form of phytochrome present due to exposure to a higher proportion of *FAR RED * light.
Plants make use of the phytochrome system to it's adjust growth based on the seasons. Through phytochrome plants is able to respond to the timing and duration of dark and light periods. At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.
After teaching a group of students about drugs used to treat hyperlipidemia, the instructor determines that the teaching was successful when the students identify:
a) HMG-CoA reductase inhibitors
d) Bile acid resins
e) Fibrin acid derivative
<u>Explanation:</u>
Hyperlipidemia is triggered by the blood containing too much LDL cholesterol and not enough HDL cholesterol to clear it up. Bad lifestyle choices will raise levels of "poor" cholesterol and lower levels of "positive" cholesterol. Hyperlipidemia is treatable but is often a disease that lasts a lifetime.
One will need to watch what you eat and do regular exercise as well and to take a prescription drug, too. The purpose is to reduce the unhealthy levels of cholesterol. Thus HMG-CoA Reductase Inhibitors (Statins), Niacin (Nicotinic Acid), Fibric Acid Derivatives (Fibrates), Bile Acid Sequestrants and Combination Therapy and Compliance are given to control.
In an ecosystem, all the trophic level in a food web are closely interlinked and any change in one level is bound to affect the other levels. The various trophic levels may correspond to producers (such as grass and plants), primary consumers (such as deer), secondary consumers (such as tigers or lions, etc.), etc. If we reduce the land available or necessary for sustaining the ecosystem by half (5 acres instead of 10 acres).
Answer:
The correct answer is villi.
Explanation:
The carbohydrates consumed by human beings are further dissociated into its mono forms, that is, fructose, glucose, and galactose. Of these monosaccharides, about 80% is glucose, which gets absorbed with the assistance of absorptive cells in the small intestine. In the walls of the small intestine, the food after digestion is passed into the blood vessels via the process of diffusion.
The mucosa or the inner wall of the small intestine is enveloped by finger-like tissues known as villi that further comprise microscopic finger-like outcrops called microvilli. These villi and microvilli enhances absorption of nutrients as they increase the surface area of the small intestine. Thus, the absorption of glucose within the small intestine is enhanced by the presence of villi.
