Match each of the following terms with its definition. 1. Mitosisa) The dense, active protoplasm found in the center of the cell
Andru [333]

Answer:

1. Mitosis c) The process of cell reproduction of human tissues that occurs when the cell divides into two identical cells

2. Nucleus a) The dense, active protoplasm found in the center of the cell

3. Cytoplasm b) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair

4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell

Explanation:

  • Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.
  • The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.
  • The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions.
  • The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.

1. RNA

2. Nucleic acid.

3. Units.

4. DNA.

5. Protein.

6. Transcription

7. Molecules

8. Units

9. Amino acids.

10. Translation.

<h3><u>Explanation:</u></h3>

Protein synthesis and the RNA synthesis is the total process that takes place together in each and every cell which is the Central Dogma theory.

In this theory, the RNAs are produced from the DNA by means of the process of transcription. In this process, the enzyme DNA dependent RNA polymerase acts as the primary DNA.

In the second step, the RNA produces the protein by the process of translation. This process involves the participation of each and every types of RNA like the rRNA, tRNA, and mRNA. These RNAs are all involved to form proteins by accumulation of amino acids and polymerizing them to form proteins.

How can i increase an object’s Kinetic Energy?
Alik [6]

- An object's kinetic energy depends on its mass and its speed.

- The faster something is moving and the heavier it is, the more work it can do.

- Kinetic energy increases as an object moves faster.

- If an objects speed is doubled > kinetic energy is quadrupled.

<em>If an object is not moving, it does not have kinetic energy. </em>
