Explanation

• The Golgi apparatus is a membrane-bound organelle that contains enzymes.
• It is responsible for processing and modifying proteins and lipids synthesized by the endoplasmic reticulum.
• It is a key component of the cellular machinery involved in protein secretion and cell signaling.

Explanation

The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.

Explanation

The blue colour of the sky is due to the scattering of light by the atmospheric particles.

Light of shorter wavelengths scatters more than the light of longer wavelengths and

the violet colour has a shorter wavelength, but our eyes are more sensitive to blue light. Hence, the colour of a clear sky is blue.

Explanation

The ozone layer lies in the stratosphere, approximately 15-40 kilometers (10-25 miles) above the Earth's surface.

The stratospheric ozone layer is Earth's “sunscreen”  protecting living things from too much ultraviolet radiation from the sun.

Oxygen layer in the atmosphere 

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer is depleting: Air pollution

Explanation

Geologists are scientists who study a planet's solid features, like soil, rocks, and minerals.

Explanation

Chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.

ozone is made up of O3

Explanation

Infrared radiation is strongly absorbed by water and by the atmosphere.

Although invisible to the eye, infrared radiation can be detected as warmth by the skin.

Nearly 50 percent of the Sun's radiant energy is emitted in the infrared region of the electromagnetic spectrum, with the rest primarily in the visible region.
