Explanation:

volume has no set mass, shape, or density. volume can be just plain air, water, gas ext...

PLZ thank and five star

and a brainliest would be nice:-)

D. the amount of space something takes up

Explanation:

For example, if you have a 2 inch by 3 inch by 5 inch rectangular block, then the volume it takes up is 2*3*5 = 30 cubic inches. We can fit 30 smaller unit cubes in this 2 by 3 by 5 block.

Another example of volume would be saying that a container can hold 5 gallons, which is the amount of liquid inside the container when it's completely full.

Extra info:

Choice A is false because a substance that does not have a definite shape would be a liquid. Liquids can flow and form to fit any volume. This also applies to a gas as well.Choice B is false because this refers to a solid. A block of ice has a definite shape which is in a block or cube form. Melting that ice will turn it into a liquid which then doesn't have a set shape.Choice C is false as this likely is talking about temperature. Temperature is the measure of how fast a particle is moving. The faster the particle, the more energy and higher temperature it has. On a cold day, the air particles aren't moving as fast compared to a much warmer day when they speed up more.

Explanation:

After mitosis two identical cells are created with the same original number of chromosomes; 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division."
