Answer:
Passive transport.
Explanation:
The transport of molecules across the plasma membrane can occur by the two process- active transport and passive transport. No amount of energy is required during the active transport.
Passive transport includes the diffusion and osmosis. Both the diffusion and osmosis do not require energy and the molecules move down from the region of higher concentration towards the region of lower concentration. Small molecules, ions and proteins can go through the passive transport.
Thus, the correct answer is option (c).

Answer:
1. Step 1: DNA Replication. Just before the cell divides, its DNA is copied in a process called DNA replication. ...
Step 2: Chromosome Segregation. The two chromosomes segregate, or separate, and move to opposite ends (known as "poles") of the cell. ...
Step 3: Separation.
2. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
