Explanation

 A sudden change in the genetic material is called a mutation

Mutations can arise from errors during DNA replication, exposure to certain environmental factors, or other types of DNA damage.

These changes can involve alterations in the nucleotide sequence, insertions, deletions, or rearrangements of DNA segments. 

Explanation

Energy is stored in the form of glycogen in animals.

Explanation

If the frequency of incident radiation in the photoelectric effect is increased beyond the threshold frequency, it will not affect the photoelectric current. 

Explanation

 Cs (Cesium), Rb (Rubidium), and K (Potassium) are all alkali metals that can form superoxides when heated in excess oxygen. 

Explanation

Explanation

Each mole of CO₂ contains 2 atoms of oxygen, which is 2 × 16 = 32 g of oxygen.

So, if 32 g of oxygen is in 1 mole of CO₂, then:

16 g of oxygen = 16 / 32 = 0.5 moles of CO₂

Explanation

The nucleotide found only in RNA is uracil (U).

While RNA and DNA share adenine (A), cytosine (C), and guanine (G), RNA utilizes uracil in place of thymine (T), which is found in DNA. 

Explanation

Van’t Hoff’s equation relates the change in the equilibrium constant (K) to temperature.

Explanation

The appearance of cloudiness in the Lucas test for alcohol is due to the formation of alkyl chlorides. 

Explanation

A battery is a device that can store:

• electrical energy in the form of chemical energy,

• and convert that energy into electricity

However, when a storage battery is being used in UPS it needs charging. 

At the time of charging the conversion of electrical energy into chemical energy is observed.
