Explanation

The moon's surface is covered with a layer of fine dust called regolith.

This layer consists of tiny fragments of rock and mineral particles created by meteorite impacts.

Explanation

Color blindness, specifically red-green color blindness.

It is a condition where a person has difficulty perceiving certain colors, particularly red and green.

Explanation

Chloroplasts contain various pigments like chlorophyll, carotenoids, and phycobiliproteins, which absorb light of different wavelengths.

This allows plants to capture a broad spectrum of light energy and use it for photosynthesis.

Explanation

The presence of an enzyme does not affect the nature or properties of the end products of a chemical reaction.

Enzymes only speed up the reaction, they do not change the final result.

The end products are the same, regardless of whether an enzyme is present or not.

Explanation

The Boolean expression for an AND gate is A . B, where A and B are the inputs.

This expression reads "A and B".

In Boolean algebra, the AND operation is represented by a dot (.) or a logical multiplication symbol (∧).

So, the expression A . B or A ∧ B represents the AND operation.

Explanation

When a wire is placed perpendicular to a magnetic field, the force on the wire is proportional to the current flowing through it.

If the current increases, the force on the wire will also increase.

Explanation

The cell membrane is also known as the plasma membrane.

It is composed of a double layer of lipids, specifically phospholipids.

Explanation

A cathode ray is a stream of electrons that are emitted from a cathode (negative electrode) in a vacuum tube.

These electrons carry a negative charge, as they are negatively charged particles.

Explanation

According to the Bronsted-Lowry theory, NH3 acts as a base because it can accept a proton (H^+).

According to the Lewis theory, NH3 is a base because it can donate a pair of electrons.

Explanation

A magnifying glass is also known as a simple microscope.

Because it magnifies objects, making them appear larger than they actually are.

It is called "simple" because it consists of a single lens.
