Answer:

Sodium potassium pump works by following several steps. 

Explanation:

1. Carrier protein binds three molecules of Na+ 

2. ATP is split, phosphate bonds to carrier. 

3. Carrier protein changes shape, and deposits Na on the outside of the cell. 

4. Carrier binds two molecules of K 

5. Phosphate is released. 

6. Potassium is released inside the cell 

Sodium -potassium pump is essential to maintain the concentration of sodium and potassium outside and inside the cell respectively.

It is the function of sodium potassium pump to transport sodium out of the cell and potassium inside of the cell against a concentration gradient.

Thus it is an active transport mechanism.

Explain why transboundary environmental threats like pollution are a problem for both parties, even if one community is principa

Gemiola [76]

Answer:

Due to its spreading nature.

Explanation:

Transboundary environmental threats like pollution is a problem for both parties i. e. one that is producing pollution and the other which is not producing it, because pollution can't remain at one place and spread from one part to another part of the earth due to open environment. So due to its spreading, it affected both the producing and non-producing parties.

If the force exerted on a sled is 100 N and the mass of the sled is 50 kg, what is the acceleration of the sled?

Anna35 [415]

<h3>Answer;</h3>

acceleration= 2 m/s²

<h3>Explanation;</h3>

From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.

That is;

F = ma

Thus; F = 100 N, m = 50 kg

a = F/m

= 100/50

= 2 m/s²

Which statement explains why earthquakes tend to be deeper near subduction zones?

ICE Princess25 [194]

Answer:

Option C, At a subduction zone, oceanic crust is forced deep into the Earth.

Explanation:

At sub-duction zone, the dense oceanic plates coincides with the less dense continental plates and thus sink below the continental plates. Sometimes these oceanic plates being dense, sink to greater depth with in the earth’s mantle. The sub-duction zone causes earth quakes of high intensity when oceanic crust penetrates to greater depths of earth crust as they tend to change the rheology of the earths’ mantle and also causes bending of plates

Hence, option C is correct
