Explain the water cycle using the terms condensation, evaporation, and precipitation.
RideAnS [48]

Answer:

The water cycle is also known as the hydrological cycle. It shows how water is circulated continuously within the atmosphere of the Earth.

Evaporation is the process where water, when heated, goes from the liquid to gaseous state in the form of vapor. This is how water gets from the geosphere to the atmosphere. As the vapor rises, the air around it gets cooler, and this is where condensation occurs. Condensation is the process where vapour will turn into its liquid state. As more vapour condense they start to form clouds. When the cloud gets dense enough, the water falls back to Earth through precipitation.

Which best explains the role of chlorophyll in photosynthesis?
Tasya [4]

Answer:

B. absorbs energy from the Sun

Explanation:

This is what Chlorophyll does. Chlorophyl's main job is to collect the energy from the sun, and then, it can help the plant make the glucose (plant food).

Look at picture for more explanation. (with picture explanation coming below Extra info)

Extra info:

I learned in my class, that Chlorophyll is on the top most layers under the epidermis and dermis of the leave's skin. There is first the Epidermis, then there are lots and ltos of chloroplast cells, then there are chlorophyll cells in it.

With Picture explanation:

1st image:

The first image shows the leaf's structure. First, you can see the epidermis (on the top), then you can see all those light green round-edged-boxes, those are all the chloroplast cells, then, inside them, are darker green cells, they are the chlorophyl cells.

2nd image:

The second image shows the structure of a chloroplast cell.

The giant light green part on the outside is the chloroplast, then inside that, there are green things, which are the chloroplast, (here they are called thylakoid, because that's the scientific word for it). And then, the other things shown are just extra info.
