What is the purpose of MITOSIS?
Mumz [18]

Answer:

D

Explanation:

A: to create sex cells of reproduction.

This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.

B. to provide the cells with food

This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.

C. To give the cell energy

This would be cellular respiration. It turns food and glucose into usable energy called ATP.

D.

This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.

Use the drop-down menus to identify the type of energy each phrase describes.
skad [1K]

Each sentence describes a different form of energy:

  • The shortest wavelength of visible light is <u>violet light</u>.
  • Energy that can be felt as heat but not seen is <u>infrared radiations</u>.
  • Short, invisible rays that can cause eye damage is <u>ultraviolet radiations.</u>
  • Visible light with the longest wavelength is <u>red light</u>.

<h3>Define electromagnetic spectrum?</h3>

An electromagnetic spectrum is a set of frequencies and wavelengths over which an electromagnetic wave can be spread (extends).

From smallest to longest wavelength (highest to lowest frequency), the electromagnetic spectrum consists of the following types of energy:

  1. Gamma rays
  2. X-rays
  3. Ultraviolet radiation
  4. Visible light
  5. Infrared radiation
  6. Microwaves
  7. Radio waves

Type of energy:

Each phrase in science describes a different form of energy:

1. Violet light has the shortest wavelength of visible light.

Visible light has a wavelength of 380 to 450 nanometers.

2. Infrared radiations are energy that can be felt as heat but cannot be seen.

Infrared radiation is a form of energy that the human body perceives as heat but that cannot be seen since it is outside the visible light range.

3. Ultraviolet radiations are short, invisible rays that might cause eye injury.

Ultraviolet light, which is mostly produced by the Sun, has the potential to harm the eyes.

4. Red light is the visible light with the longest wavelength.

Red light has a wavelength of 620 to 750 nanometers.
