Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient 
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body

Answer:
All living objects are composed of cells, including you. Cells are the basic element of existence. Such cells are known as prokaryotes and eukaryotes. Procaryotes are cells not possessing a nucleus, or organelles comprising the genetic material of a cell, or other membrane-bound organelles.

A transport system that moves one solute into the cell and another one out of the cell during a single cycle accompanied by the expenditure of energy through ATP hydrolysis could be called a(n)  active transport.
<h3><u>
Explanation:</u></h3>
A system of transport that helps in the movement of  one solute in a cell and the other out of the cell with a release of energy through ATP hydrolysis is an active transport. Active transport refers to the process that facilitates the molecules or ions to move across a cell membrane. This process requires enzymes and energy.
The movement of the ions or molecules inside a cell or out of the cell occurs across they cell membrane  from the lower concentration region to the higher concentration region is the active transport process. It is always related to the accumulation process of ions, amino acids glucose which are higher concentration molecules.
