Explanation:
From DNA we are able to get RNA (m and t) to make proteins
Answer: B and D
Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.
Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.
This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.

An example of the liver is an organ.
The liver is positioned on the right side of our stomach, and is colored reddish-brown. The liver aid us to get rid of damaging substances and benefits us to keep the body natural of contamination. The liver also is treated as a gland, due to generating bile (needed to consume fats). The liver can likewise help us wipe out aged blood cells, eliminates unhealthy substances such as alcohol and narcotic types, and also serves in balancing iron and vitamins in us.
The global distribution of organisms and the unique features of island species reflect the evolution and geological change. Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
