The process of deciding which combination of half chromosomes (chromatids) is completely random just like tossing a coin is completely random.
Answer:
Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.
The answer is <span>Lysosomes
Lysosomes are the organelles in charge of digesting and breaking down all matter in a cell that needs to be broken down, varying from food and energy molecules to viruses and bacteria.</span>
