Drop and roll on the floor to extinguish the fire.
Answer:
I believe the correct answer is both involve proteins in the cell membrane.
Explanation:
This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.

During puberty the testes of the man will begin to produce testosterone. This causes hair growth in multiple areas of the body and the voice change. Similarly, women begin to grow hair but also begin menstruation.

Hello!
The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.
<h2>Why?</h2>
The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.
In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.
If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.
Have a nice day!
