Answer: a. dead organisms from the marine food web.
c. liberation through ATP hydrolysis in living organisms.
Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.
If a client is being treated for diverticulosis, the following points
should be included by the nurse in the client's teaching plan:
- Do not suppress the urge to defecate.
- Avoid constipation
- Drink at least 8 to 10 large glasses (Approximately
2 Liters) of fluid every day.
- Include foods that are soft but have increased
fiber in your daily diet
- Avoid the use of laxatives or enemas except when
recommended by the physician.
- Exercise regularly if the current lifestyle is
somewhat inactive.
Answer:
The third option, Light intensity has an impact on the rate of photosynthesis.
Explanation:
Light is a limiting factor at low intensity. Thus the rate of photosynthesis increases with an increase in light intensity. High light intensities affect the rate of photosynthesis. It increases the temperature of the leaves. Therefore, rate of transpiration increases
Answer:
Wrinkled peas need to have genotype rr, since the wrinkled trait (r) is recessive
Answer:
This question is incomplete, the complete question is:
Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color. Red eye color is dominant to brown eye color. Use the Punnett square to determine the ratio of offspring with: Brown body and red eyes : Brown body and brown eyes : Black body and red eyes : Black body and brown eyes :
The answer is:
Brown body and red eyes : 9
Brown body and brown eyes : 3 Black body and red eyes : 3 Black body and brown eyes : 1
Explanation:
This question is a typical dihybrid cross involving two different genes. One coding for body color and the other for eye color. The allele for Brown body color (B) is dominant to the allele for black body color (b) in the first gene while the allele for Red eye color (R) is dominant to the allele for brown eye color (r) in the second gene.
In a cross between two parents that are heterozygous for the two genes i.e. BbRr × BbRr, each parent will produce the following possible allelic combinations of gametes:
BbRr- BR, Br, bR, and br
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced in the ratio 9:3:3:1 where the offsprings and their possible genotypes are;
Brown body and red eyes (B_R_): 9
Brown body and brown eyes (B_rr): 3
Black body and red eyes (bbR_): 3
Black body and brown eyes (bbrr): 1
