Cell replication process is also called as mitosis. In mitosis, the cell goes through 4 steps: Prophase, metaphase, anaphase, and telophase. This eventually produces 2 daughter cells. Cell replication in which gametes are produced is called meiosis. Meiosis also goes through 4 steps, but twice; therefore producing 4 daughter cells with half of the genetic content. Common in these two processes is the splitting of the cytoplasm to form the daughter cells which is called cytokinesis.
Species are defined as organisms that interbreed naturally and produce viable offspring.
<span>there are some animals that can interbreed, such as horses and donkeys, but their offspring are not fertile.</span>
Central nervous system depressment
Answer:
Explanation:
Active cellular transport:
- It is the movement of molecules against the concentration gradient (from low concentration to high).
- Active transport requires expense of energy supplied by ATP.
- It is a rapid way to transport of large sized molecules.
Passive cellular transport:
- It is the movement of molecules along the concentration gradient (from high concentration to low).
- Passive transport does not require expense of energy.
- It is a slow process and small sized molecules get transprorted.
