Explanation

Root hairs are tubular outgrowths of root cells that increase the surface area for absorption of water, salts, and minerals from the soil.

Explanation

Weather satellites are used to provide weather forecasting and monitoring of weather patterns, climate change.

Explanation

• A plane mirror produces an image that is the same size as the object.
• The mirror doesn't magnify or reduce the image, it simply reflects it.

Explanation

• Transmission occurs when light passes through a substance without being absorbed, reflected, or refracted.
• The light wave maintains its intensity and direction as it travels through the substance, emerging unchanged on the other side.

Explanation

• An element is a substance that consists of only one type of atom and cannot be further split up into simpler substances by chemical reactions.
• Examples: hydrogen (H), carbon (C), oxygen (O), and iron (Fe).

Explanation

• Plants don’t need shelter but they need air.
• Air provides the necessary carbon dioxide for photosynthesis and oxygen for respiration.

Explanation

• Carbon Dioxide (CO2) is the gas used to produce energy in the form of glucose during photosynthesis.
• CO2 is the source of carbon atoms, which are used to synthesize glucose and other organic compounds during photosynthesis.

Explanation

• Chromosomes are thread-like structures in the nucleus that carry genetic information in the form of DNA.
• They contain the instructions needed to build and maintain the cell, and control its functions.

Explanation

• When a ray of light strikes a brick wall, it is reflected by the wall.
• This is because brick walls are opaque.
• It means they do not allow light to pass through them.
• Instead, the light bounces back, or is reflected, by the wall.

Explanation

• Transparent objects allow light to travel through them without scattering or absorbing any of the light.
• Examples: Glass, water, air, plastic and wrap.
