Answer:
A. He has a large buildup of lactate in his muscles.
Explanation:
Ideally, our body cells, via the process of aerobic cellular respiration, need oxygen to break down glucose. However, during rigorous activities or exercises, oxygen can become unavailable for use. In this case, the body cells switch to use another way of cellular respiration, which is FERMENTATION.
This fermentation causes a build up of lactic acid/lactate (its byproduct) in the cells of the muscles being used, which physically causes a burning and aching sensation just as the case of this hiker. The climbing of the steep path is causing causing the fast usage of oxygen in his cells.
Answer
The seasons of the year, location of low and high pressure systems and air temperature all affect when and where a jet stream travels. Jet streams form a border between hot and cold air.

Answer:
Ozone molecules in the stratosphere are constantly being produced and destroyed by different types of UV radiation from the sun. ... However, scientists have discovered that certain chemicals react with UV radiation in the stratosphere, which causes them to break apart and release chlorine or bromine atoms.
Explanation:
To find the surface area to volume ratio, we first need to find the surface area and the volume.
To find surface area, we just need to take the area of one of the faces and multiply that by 6 (since there are 6 faces on a cube).
We know that the length of one side is 3cm. To find the area of one face, we just need to multiply length * height. Since it's a cube, length and height will be the same.
3 * 3 = 9
The area of one face is 9. To find the surface area of the cube, we need to multiply the area of one face by 6.
9 * 6 = 54
The surface area of the cell is 54cm2.
Now to find volume.
The volume of a rectangular prism is simply length by width by height.
3 * 3 * 3 = 27
The volume of the cell is 27cm3
The surface area to volume ratio for this cubical cell is 54:27, or 2:1.
Hope this helped =)
