Explanation

Molten NaCl conducts electricity because of the presence of free ions. 

When sodium chloride (NaCl) melts, the ionic bonds holding the sodium (Na+) and chloride (Cl-) ions together break, allowing them to move freely within the liquid.

These mobile ions can carry electrical charge, thus enabling the molten salt to conduct electricity. 

Explanation

 A LASER beam can be sharply focused because it is highly coherent. 

Coherence refers to the well-organized nature of light waves in a laser beam, where all the waves are in phase with each other, allowing them to be concentrated into a small, focused spot

Explanation

The false statement regarding Hepatitis A virus is Causes chronic liver disease. 

 Hepatitis A is typically a mild, self-limiting illness that does not lead to chronic liver disease unlike hepatitis B and C. 

Explanation

The tertiary structure of a protein refers to its complex, folded shape in 3D space, which is crucial for enzyme function.

This structure is formed by interactions between the amino acid side chains within the polypeptide chain,

Including hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges

Explanation

Explanation

 The bones in the long axis of the body make up the axial skeleton 

The axial skeleton includes the bones that form the central axis of the body, like the skull, vertebral column, and ribs. 

Explanation

 Trial-and-error learning involves repeatedly trying different actions or strategies until one leads to a successful outcome.

Classical conditioning, on the other hand, is a type of learning that involves associating two stimuli, such as a neutral stimulus (like a bell) with a naturally occurring stimulus (like food).

The association leads the animal to respond to the neutral stimulus as if it were the natural stimulus.

This process doesn't require trial and error; the response is learned through repeated pairings of the stimuli. 

Explanation

A microwave oven heats food by using electromagnetic radiation at a specific frequency

That resonates with the water molecules in the food, causing them to vibrate and generate heat.

This process of energy transfer due to matching frequencies is called resonance. 

Explanation

Potassium dichromate acts as a strong oxidizing agent. 

Potassium dichromate is a powerful oxidizing agent, meaning it readily accepts electrons from other substances, causing them to be oxidized.

This characteristic is widely utilized in various chemical reactions and industrial processes where it's employed to oxidize other substances, particularly in acidic media

Explanation

 An aromatic alcohol is an alcohol where the hydroxyl group (-OH) is attached to a carbon atom that is part of an aromatic ring (like benzene).

Benzyl alcohol has the chemical formula C6H5CH2OH,

Indicating that the -OH group is attached to a carbon atom that is part of a benzene ring.
