Explanation

Immunization is actually the process of becoming immune to a disease, typically through vaccination.

It is not an effect of misusing antibiotics.

Explanation

Plants exhibit chemical coordination, also known as hormonal coordination, which involves the use of plant hormones or phytohormones to coordinate activities such as:

• Cell growth and differentiation
• Root and stem elongation
• Leaf senescence
• Flowering and fruiting
• Response to environmental stimuli

Explanation

The lens in the human eye is a convex lens, meaning it is thicker in the middle than at the edges.

This shape allows it to focus light rays convergently, creating a real image on the retina.

A convex lens is also known as a converging lens, as it converges light rays to a focal point.

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

CH3-CH2-CH3 is the molecular formula for propane, which is a saturated hydrocarbon (an alkane).

Explanation

A stimulus is detected by a receptor.

It is a specialized cell or structure that converts the stimulus into an electrical signal that can be transmitted to the nervous system.

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

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.

Explanation

When water waves pass from a deep region to a shallow region, they are refracted, which means they change direction.

The speed and wavelength of the waves also change, but the frequency remains constant.
