2.Patsy is studying different kinds of weathering. She has four pans full of dried modeling clay. Some she adds water to. Some she freezes overnight, then lets thaw, as summarized in the table below: PanAdded Water?Froze the pan?1yesyes2yesno3noyes4nono Then she compares the clay in all four of her pans. The clay in pan #4 was the same at the end of the experiment as it has been at the beginning. The clay in pan #1 had changed and broken up more than the others.  Which of the following conclusions could Patsy have made? Frozen clay takes up more space than thawed clay does. Adding water to clay and then freezing it breaks the clay apart more than either freezing it or adding water to it alone. Adding water to clay and then freezing it helps plants to grow in the clay more than either freezing it or adding water to it alone. Wet clay takes up more space than dry clay does.

How does the size of a cell’s surface area change compared to its volume when the cell grows?

Answers

Answer:

Surface area does not increase after certain growth with the same pace as the volume increases.

Explanation:

The volume of cell increases rapidly as compared to its surface area when the cell grow in size and this is the reason due to which which its surface area to volume ration gets smaller  leads to reduction in surface diffusion. After a certain growth,the surface area does not increase as the material that forms the surface of the cell cannot increase further . Therefore at this stage the cell must divide and produce smaller cells which are able to accommodate favorable surface area/volume ratios

Which statement describes what happens to elements during radioactive decay?A-They release energy.
B-They gain new particles.
C-They lose energy at a varying rate.
D-They have a consistent number of particles.

Answers

Answer:

The correct answer is option A-"They release energy".

Explanation:

The phenomenon of radioactive decay, also known as radioactivity or nuclear radiation, occurs when an unstable atomic nucleus emits radiation and loses energy and mass in the process. The elements during radioactive decay release energy and mass trying to reach a stable form. The material that has the unstable nucleus is considered radioactive.

Answer:

Option (A)

Explanation:

Radioactive decay is usually defined as a process by which an unstable nucleus of an atom continuously disintegrates into a stable nucleus, resulting in the liberation of a large amount of energy as well as matter.

The radioactive substances undergoes radioactive decay and these released energy is very harmful as they are emitted in the form of ionizing radiation.

These process of radioactive decay is commonly known as radioactivity.

Thus, the correct answer is option (A).
