Which of the following statements is true about passive transport?
user100 [1]

Answer:

No cellular energy is needed in the Passive transport.

Explanation:

A movement of atomic molecules and ions throughout the cell membrane is known as passive transport. In this transportation of molecules no cellular energy is used.

As this movement is influenced by the tendency to grow as entropy, the energy is not in need unlike the active transport. Its rate depends on the permeability of cell membrane. There are four types of passive transport- facilitated diffusion, simple diffusion osmosis or filtration.

The two graphs shown below represent data collected from the same lake
Natali [406]

Answer:

C. The trout population decreases as oxygen levels decrease.

Explanation:

We can see that the relationship between the number of trout and time passed is decreasing from the graph on the right because its line is decreasing. From the graph on the left, we can see that oxygen is decreasing as time goes on. Thus, we can interpret that the trout population decreases as oxygen levels also decrease; a proportional relationship.

The other options are incorrect because we can actually see that for...

A; the population of whitefish actually decreases as oxygen levels also decrease.

B; the population of carp actually increases significantly as sewage levels increase.

D; the walleye population actually also decreases overall as sewage levels increase.

What type of wave interaction allows you to hear someone and not see them?
FrozenT [24]
Hello,

The answer should be "sound waves".

Reason:

If a gun go off the sound waves can go through anything to allow the person to hear for example: the sound wave can go through walls, water, and hard surface. It can also allow you to hear something but not see it therefore the answer is sound wave!

If you need anymore help feel free to ask me!

Hope this helps!
