When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
Answer:
Fertilization
Explanation:
Cell division is the process that occurs in all living organisms by which a cell divides into two or more daughter cells. The purpose of vegetative cell division (mitosis) in eukaryotes is maintenance of the cell's genome, growth by cell multiplying and tissue renewal by producing new cell. Reproductive cell division-meiosis is responsible for the formation of gametes for the further reproduction. In prokaryotes it is used as a form of reproduction ( binary fission).
Answer: B- Bacteria
Explanation: Bacteria are infinitesimal organisms that have single cells that grow in different atmospheres. They have an easily understood inside arrangement. Their cells are normally surrounded by two shielding coverings which are an external cell continuous vertical structure and a cell pliable sheet-like structure acting as a boundary inside. However, some bacteria do have a third shielding sheet furthest from the center named the capsule.
Answer:
Answer is B if we have the same one
Explanation:
The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.
