How can the freezing of surface waters make the water that is left unfrozen denser

Answers

Answer 1

Explanation:

When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.

Answer 2

this is because water expands as it gets cold hence floating leaving the unfrozen water dense

Why is animal testing bad?

Answers

Answer:

Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.

Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.

A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?​

Answers

Answer:

Because they don't have fertilizer.

Explanation:

Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)​

Answers

Answer:

False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.

Explanation:

Hope this helps.

It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.

What is nuclear envelope made of?

The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.

In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.

The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).

Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.

Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.

Thus, the given statement is true.

Answers

Answer:

The correct answer would be - option C. the time that it takes you to get to the school.

Explanation:

The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.

Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.

Plants take in carbon dioxide and release gas​

Answers

Answer:

yes, but by gas you mean oxygen right?

Explanation:

Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Explanation:
