Irina-Kira [14]

Answer: B) proteins in the membrane act like gates to control entrance and exit of molecules.

Explanation: Plasma membrane is composed of phospholipids bilayer in which the hydrophobic regions of the phospholipids face each other to form the core of the bilayer. Proteins are embedded in the bilayer through an interaction between the amino acid side chains and the nonpolar acyl chains of the phospholipids. The embedded membrane proteins form channels for passage of ions and other molecules. Each membrane protein is selected for one or more ions or molecules that passes through it. The membrane is said to be semipermeable because it allows the passage of some molecules and excludes the passage of others.

What are the phases of Mitosis and what happens in each phase?
Norma-Jean [14]
Interphase: Chromosomes duplicate, and the copies remain attached to each other.

Prophase: In the nucleus, chromosomes condense and become visible. Spindle fibers begin to form.

Prometaphase: The nulcear membrane breaks apart, and the spindle starts to interact with the chromosomes.

Metaphase: The copied chromosomes align in the middle of the spindle.

Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.

Telophase: Nuclear membranes form around each of the two sets of chromosomes, they begin to spread out, and the spindle begins to break down.

Cytokinesis: The two cells split into two daughter cells, each with the same number of chromosomes as the parent cell.
