Answer:
Low concentration to high concentration
Explanation:
If moving up the concentration gradient, you will start detecting the chemical molecules more and more frequently.
Answer: Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the concentration gradient, which requires additional energy.
Explanation:
The order is:
interphase
prophase
metaphase
anaphase
telophase
(the way i remember it is "IPMAT")
Answer: The pH scale measures whether there is more hydroxide or hydronium in a solution.
Is important because it tells you how basic or acidic the solution is.
