1. Blood in the gills runs in the opposite direction as the water outside the gill filaments. By running in the direction opposi

te the flow of water, the blood is always exposed to an area of water that has a higher level of oxygen. Oxygen moves across the membranes by diffusion. So if the gill had more oxygen than the water, the fish would lose oxygen to its surroundings. This is an example of:

Answer:

Counter current  system  for oxygen exchange. This  process allow the exchange through diffusion of oxygen from higher concentration of water to lower concentration in the fish blood, from the surface of the  fish lammela,Therefore as  blood flows through the gill capillaries,oxygen at higher diffusion gradient,enters the capillaries, sustained by higher diffsuion rate of Oxygen Counter by opposite blood flow.

5. Which of the following is an example of active transport?
Nadusha1986 [10]

Answer:

D (proteins moving ions from low to high concentration across a cell membrane)

Explanation:

Active transport, by definition, is a type of substance transport that requires energy (typically in the form of ATP). Having said that, we can immediately eliminate B (aka water diffusion throughout the cytoplasm of a cell), as diffusion (osmosis in this case) does not require any expenditure/spending of energy. Next, we can cancel A and C because although they do require energy, there is no transport involved. Thus that leaves us with D. D is not only the answer because of the process of elimination but also b/c the ans. choice says that ions are being moved from low to high concentration, which is against the concentration gradient and thus requires energy. Hope you found this helpful! :)

3. MS-ESS2-5. What usually happens when a cold front and a warm front collide? Tornadoes Rain High Wind all of the above​
Illusion [34]

Answer:

The correct answer is - all of the above.

Explanation:

If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.

It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.
