(of a cell or nucleus) having a single set of unpaired chromosomes.
hope this helps
pls mark me as the brainliest
The sun! It's solar radiation heats our planet, gives us light, and sustains life.
It moves by the process of active transport which happens against the concentration gradient
The order of which you add two integers does not effect the sum for example:
Jane dives five feet then three feet, that is 5+3= 7 ft.
Sarah dives three feet then five feet, that is 3+5= 7ft
as you can see they both dived the same exact feet, the order does not matter.
Answer:
Cell membrane
Explanation:
In the cell membrane, there is the process of transport of substances, with energy expenditure, through the mediation by specific carrier proteins.
This usually occurs from the lowest to the highest concentration medium in the cell (against the concentration gradient). This process is called active transport.
Some examples of substances that can be actively transported across the membrane are: Iron, potassium, iron, hydrogen, calcium and sodium ions (as described in the question), as well as some types of amino acids and sugars.
