Limestone is made up of calcium carbonate. How would you expect the pH of the lake with limestone bedrock to compare with other lakes with several years of acid rain.

Answers

Answer 1

Answer:

Answer:

See the answer below.

Explanation:

One would expect the pH of a lake with limestone bedrock to be higher than that of other lakes with several years of acid rain.

A lake with a bedrock made of limestone would be alkaline due to the weathering of the bedrock and the alkaline nature of calcium carbonate. Lakes with several years of acid rain would, of course, be acidic.

Generally, pH above 7 is alkaline while the ones below 7 are acidic. Hence, the pH of a lake with limestone bedrock will be higher (above 7) than the pH of other lakes with years of acid rain (below 7).

Which of the following processes would convert inorganic phosphorus in a rock to an organic form of phosphorus?

Answers

Weathering is a process by which inorganic phosphorous in a rock is broken down into soluble form by coming into contact with the atmosphere, water and the biological organisms. This phosphorous is then taken up by plants and converted into its organic form.

It's actually plant uptake.

In plant cell what does the vacuole do

Answers

I found this on a website..... Hope this helped :)

"In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food."

Vacuoles might store food or any variety of nutrients a cell might need to survive.
