Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.

Answer:
b: time
Explanation:
When meteorologists need to make a forecast they analyze different measurements in order to accurately make a forecast, these include patterns of winds, pressure, pressure change, temperature, humidity, clouds, and hygrometers. From the answers provided the one measurement that is not used is time. Mainly due to the fact that weather does not depend on the time of day, and any type of weather can be present at any time if the right circumstances exist.
The answer is C genetic variation
Answer:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. It was proposed by Alfred Wegener.
