Answer:
active transport
Explanation:
Active transport -
It refers to the movement of the molecules from a region of lower concentration towards a region of higher concentration via a membrane , is referred to as active transport.
The process of active transport need to have some cellular energy .
Hence,
The concentration of potassium is maintained in the red blood cells via the process of active transport.
In nature, water exists in the liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at 0 degrees Celsius and 1 atm of pressure. At room temperature (approximately 25 degrees Celsius), it is a tasteless, odorless, and colorless liquid.
Answer:
Once the sun comes up, the sunlight excites the cold air in the first foot or so above the ground (which can be 10 or more degrees colder), which causes it to move around and mix into the next several feet of air. That “mixing upward” drops the temperature of the air at thermometer level.
Explanation:
A change in the force of gravity on an object will affect its weight.
