Where does the po32– come from that circulates due to upwelling? select all that apply.
IRISSAK [1]

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.

Which of the following statements about 2,3-bisphosphoglycerate (BPG) binding is FALSE?
Kitty [74]

Answer:

The answer is C. BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen

Explanation:

The 2,3-bisphosphoglycerate (BPG) which can also be referred to as the 2,3 - di phosphoglycerate , is being produced by the red cells and has the ability to deoxygenate hemoglobin. This is because , his accumulation results to a decrease in the affinity for oxygen, this means that , it will convert hemoglobin to a low oxygen affinity state.

In this case, comparing the options given, it will be concluded that, 2,3  -biphosphoglycerate {BPG} does not aids the delivery of oxygen to tissues, but  decreases the affinity of oxygen, which deoxygenate hemoglobin, and causes the concentration of the carbon dioxide to increase.

What motion is observed in a horse once the ischial arch is passed with a urinary catheter?
never [62]

Answer: Option A.

It lowers the head.

Explanation:

The ischial arch is a prominent structure closer to the colliculus seminalis of horse. The ejaculatory duct is lateral to this and correspond to the area of ductus differenc eand vesicular gland opening.

The vesicular glands can be easily catheterized using a small-diammeter, flexible polyethylene catheter or a stylet . The catheter is inserted into the instrument channel of the videoendoscope and serves as a route for direct aspiration of fluid or instillation of pharmacologic solutions for direct treatment.It also helps to guide the scope head into the seminal vesicle .
