Answer:
polar climate zone

the equator of the earth is the area where most of the suns rays hit the surface area. as you move towards the poles, areas receive less sunlight. the top of the poles receive the least solar radiation and are the coldest places on earth, hence the climate zone name polar.

Answer:
1. telescope
2. astronomers
3. radio waves
Explanation:
A telescope allows one to magnify what they're looking at to see it closer than it actually is. Astronomers are those that study planets, stars, and other celestial bodies in space. Modern telescopes have the ability to detect radio waves from astronomical objects that emit them from far away. This allows us to see what we normally would not be able to.
<span>the undigested lactose in the intestine draws water into the large intestine and is broken down by bacteria.
Lactose intolerance is due to the body no longer producing the enzyme required to break down the disaccharide sugar called lactose into the monosaccharide sugars glucose and galactose. Those undigested sugars provide food for bacteria that in turn generate gas. With that in mind, let's look at the available options to see which one is correct.
the lactose is an irritant to the stomach.
- I hope not. Because babies world wide need lactose for their growth. So this is a wrong answer.
the lactose in the small intestine neutralizes enzyme action.
- There's a lot of different enzymes used in the digestive process. And it's the lack of the enzyme lactase that causes lactose intolerance. But lactose doesn't neutralize any enzymes, so this is a wrong answer.
the undigested lactose in the intestine draws water into the large intestine and is broken down by bacteria.
- This looks reasonable. This is the correct answer.
the presence of lactose in the small intestine causes the gall bladder to contract more forcefully?
- This one is just plain silly. Wrong answer.</span>
