<h2>Answer:</h2>
The option C is the correct answer.
Which is, "He varies the nitrogen and carbon dioxide levels in the air from one trial to the next".
<h3>Explanation:</h3>
The hypothesis of Malik was about the effect of increased oxygen level on the growth of the red-legged grasshoppers.
So the areas of his experiment should be the:
- Grasshopper type.
- High oxygen level.
- Rate of growth of grasshopper.
So all the given options are relevant to his experiment except the third one.
So varying the nitrogen and carbon dioxide level in air could not contribute in his experiment.

Just like any other gas or mixture of gases, the gas molecules are
zipping around in all different directions and with a whole range of
different speeds.
Those that happen to be moving at a speed greater than the Earth's
"escape velocity", AND are pointed away from Earth, AND don't hit
any other molecules before they escape, are lost.
With the combination of Earth's escape velocity, and the temperatures,
thickness, and density of the atmosphere, that process happens slowly
enough to have maintained an atmosphere around this planet until now.
Personally, I hope it hangs around for a while longer. But with the constant
increase in temperature that's been going on, you never know . . .
Answer:
east of south
Explanation:
Given:
- distance of the person form the initial position,
- direction of the person from the initial position,
north of east
- distance supposed to travel form the initial position,
- direction supposed to travel from the initial position, due North
<u>Now refer the schematic for visualization of situation:</u>
...............(1)
.................(2)
<u>Now the direction of the desired position with respect to south:</u>
east of south
<u>Now the distance from the current position to the desired position:</u>
the answer is C
