Explanation:
Answer;
A. During active transport, a material may be moved from an area of low concentration to an area of high concentration.
Explanation;
-Active transport involves movement of molecules or particles against a concentration gradient (from a region of low concentration to a region of high concentration). This movement of particles against the concentration gradient requires an input of energy from the cell in the form of ATP.
- Passive transport on the other hand involves movement of materials from a region of high concentration to a region of low concentration and does not utilize energy. Passive process are processes such as osmosis and diffusion.
Answer:
The correct answer is b. false.
Explanation:
Two hydrogen bonds are formed only between Adenine and Thymine because that's how their chemical structures allow them to bind. On the other hand, Cytosine and Guanine form three hydrogen bonds. This difference in the bonds is what gives the DNA its structure.
