False I think lol srry if not false
Answer:
Any process that involves active transport most often involves the expenditure of energy in the form of ATP hydrolysis.
Explanation:
Active transport in cells is a form of transport which involves the transport of solute molecules across a membrane against a concentration gradient using energy provided from some chemical reaction occuring in the cell.
Active transport is an endergonic (energy-requiring) process and therefore, must proceed only when coupled to an exergonic (energy-releasing) process such as the breakdown of ATP, an oxidation reaction, absorption of sunlight, etc.
In many instances in cell, such as the Na/K pump, ATP hydrolysis is the the common exergonic reaction to which active transport is coupled to.
C. A wall of stones and mortar
This would act as a model describing the cell membrane.
Explanation;
A cell membrane is made up of a phospholipid bilayer with embedded proteins.
A cell membrane hold the different components of the cell together and to protect it from the environment outside the cell. It acts as a boundary between the inside environment and the outside environment of a cell.
It regulates the materials that enters and exits the cell; through selective movement of substances in and out of the cell.
<span>Please remember that spring tides occur approximately twice a month, when the earth and moon and sun are about co-linear. That is about at full moon and about at new moon.
Neap tides occur at half moons, when the moon is off to the side of the line between earth and sun. I hope this can help</span>
