Explanation

Homeostasis is the set of metabolic reactions that maintain the internal environment of an organism, regulating factors.

Such as temperature, pH, blood sugar levels, and blood pressure.

Explanation

Amphoteric substances are those that can react with both acids and bases.

They can donate or accept protons (H+ ions), depending on the conditions.

Examples of amphoteric substances include water (H2O), amino acids, and certain metals like zinc and aluminum.

Explanation

Alpha (α) radiation consists of heavy, positively charged particles (alpha particles) that are emitted from the nucleus of an atom during certain types of radioactive decay.

Alpha particles are highly ionizing, meaning they can efficiently remove tightly bound electrons from atoms, resulting in the formation of ions.

Explanation

Chondrocytes are the cells that make up cartilage, a type of connective tissue found in various parts of the body, such as joints, ears, nose, and ribs.

Chondrocytes produce and maintain the cartilage matrix, which consists of collagen and proteoglycans.

Explanation

The Frontal Lobe (part of the Cerebrum) controls reasoning, planning, and problem-solving.

More Details
Cerebellum → balance & coordination,
Medulla → involuntary actions,
Cerebrum → higher thinking functions, divided into 4 lobes (Frontal, Parietal, Temporal, Occipital).

Explanation

Bernoulli’s Principle explains that faster airflow over the wings creates lower pressure, producing lift that keeps the airplane in the air.

Explanation

Parsec (per sec) is an astronomical unit used to measure large distances between stars or galaxies.

1 parsec ≈ 3.26 light years.

Explanation

• Wavelength is the distance between two consecutive points on a wave that are in phase.
• It is typically denoted by the symbol λ (lambda).

Key Points:

• Time period (T) is the time taken by the wave to complete one oscillation.
• Frequency (f) is the number of oscillations per unit time.
• Amplitude (A) is the maximum displacement of the wave from its equilibrium position.

Explanation

Systematic errors are caused by faulty or improper functioning of instruments, or by a flaw in the experimental design.

These errors are consistent and repeatable, and can be identified and corrected.

Explanation

A NOT gate, also known as an inverter.

It is a digital logic gate that negates the input signal.

If the input is "1", the output will be "0".

If the input is "0", the output will be "1".

The truth table for a NOT gate is:

Input | Output

-----|------

0 | 1

1 | 0
