compare and contrast coal and nuclear power. would you support either of both of these forms of energy technology. why or why not?

Answers

Answer:

I will give you a basic idea of what you should write in my opinion you should support neither of these forms of energy mainly due to the reason that both forms of energy pollute the world. instead we should focus on using renewable energy such as solar wind and hydro. furthermore coal and nuclear power are non-renewable resources which means that there is only a limited amount on the earth which brings up the benefit of having renewable energy as there is endless supply of it.

Hi :)

A hypotonic solution has a lower concentration of solutes than another solution

In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol

Bound to free ribosomes
Based on the diagram, what is the site of modification and packaging of
proteins and lipids prior to export from the cell?

Answers

Answer:

1. Embedded in the plasma membrane

2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.

Explanation:

1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.

2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.

The most likely location of cholesterol in an animal cell is A. Embedded in the plasma membrane.

Based on the diagram, the site of modification and packaging of proteins and lipids prior to export from the cell is the Golgi apparatus.

Cholesterol simply means a fat molecule that is formed in the smooth endoplasmic reticulum of animal cells.

It should be noted that the cholesterol is then sent It is then to the plasma membrane,

The Golgi apparatus is an organelle that can be found in eukaryotic cells. The function of the Golgi apparatus is the modification and the packaging of the lipid molecules and the protein molecules that are produced.
