Explanation

The formula to calculate potential difference (V) is:

V = W / Q

Where:

W = work done (in Joules)

Q = charge (in Coulombs)

Given:

W = 600 J (work done)

Q = 2 C (charge)

V = 600 J / 2 C = 300 V

So, the potential difference is 300 V.

Explanation

Ethanol gives the iodoform reaction because it contains a methyl group adjacent to the hydroxyl-bearing carbon.

It forming iodoform (CHI₃) when reacted with iodine and a base.

Explanation

The correct Arrhenius equation is K = Ae^(-Ea/RT).

In this equation, K is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the universal gas constant, and T is the absolute temperature in Kelvin.

This equation illustrates how the rate constant increases with temperature and decreases with higher activation energy.

Explanation

The correct option about endospore is that it endures extreme conditions.

Endospores are highly resistant structures formed by certain bacteria.

It allowing them to survive harsh environmental conditions such as heat, desiccation, and radiation.

Explanation

Gene mutation increases variation within a gene pool.

Mutations introduce new alleles into a population.

It leading to genetic diversity and potentially new traits.

Explanation

When glycerol reacts with fatty acids, an ester bond will form.

This reaction occurs during the process of esterification, where glycerol combines with fatty acids to create triglycerides.

They are the main constituents of body fat.

Explanation

The medulla oblongata is a part of the hindbrain.

It is responsible for regulating vital functions such as heart rate, breathing, and blood pressure.

• Cerebrum
• Thalamus
• Hypothalamus
• Limbic system

• Tectum
• Tegmentum
• Substantia nigra

• Medulla oblongata
• Pons
• Cerebellum

Explanation

The formula for calculating the frequency of genotypes and alleles in a population gene pool is known as the Hardy-Weinberg Equation.

It provides a mathematical framework to study genetic variation in populations under ideal conditions.

Explanation

An artificial radioactive element can be made by bombarding high energy particles on stable elements.

This process can induce radioactivity in the stable element.

This resulting in the formation of a new radioactive isotope.

Explanation

Folic acid is not an amino acid; it is a B vitamin (B9) important for DNA synthesis and repair.

In contrast, lysine, glutamic acid, and glycine are all amino acids that serve as building blocks for proteins.
