Chemistry
1 answer:
bearhunter [10]3 years ago
7 0

Answer:

It helps microorganisms grow

Explanation:

I think this is the correct answer because I tried searching it up and you sterilise the petri dish before adding the agar, I've used agar in petri dishes a year ago and im pretty sure they don't make cells glow or make bacteria appear larger.

if I had to have a second guess I'd go with the first one but considering the fact that bacteria is usually to small to see with the naked eye the last option seems correct

Starting with the water in the ocean place the below steps in the correct order showing how water moves through this cycle
ruslelena [56]

Answer:

C, A, D and B

Explanation:

Water evaporates from the surface of the oceans leaving behind salts. As water vapor rises, it collects and is stored in clouds.

As water cools in the clouds, condensation occurs. Condensation is when gases turn back into liquids.

Condensation creates precipitation. Precipitation includes rain, snow, hail and sleet. The precipitation allows the water to return again to the Earth's surface.

When precipitation lands on land, the water can sink into the ground to become part of our underground water reserves, also known as groundwater.
