Explanation

 The common cultivated potato, Solanum tuberosum,

It has 48 chromosomes in its somatic cells (2n=4x=48).

This means it is a tetraploid species, with two sets of chromosomes derived from each of its two parents.

Therefore, the number of chromosomes in a potato's egg cell and in haploid somatic cells is 24. 

Explanation

The photoelectric effect best explains the particle nature of light. 

Explanation

Actinopods are a group of protists that use specialized pseudopodia, called axopodia, for locomotion and capturing food. 

Explanation

The quantum number that describes the shape of an electron in an atom is the azimuthal quantum number (l). 

Explanation

Raney nickel is prepared by treating a nickel-aluminum alloy with a concentrated solution of sodium hydroxide.

This process, also known as activation, dissolves much of the aluminum, leaving behind a porous, highly active nickel catalyst. 

Explanation

The tiny thin-walled ducts in the lungs of birds that open at both ends are called  Para-bronchi. 

In bird lungs, instead of alveoli, there are these thin-walled tubular structures called parabronchi where gas exchange occurs. 

Explanation

A group of carbohydrates containing 3 to 10 monosaccharides in straight or branched chains is called oligosaccharide.

These chains are linked together by glycosidic bonds. 

Explanation

According to Erwin Chargaff's 1951 findings, the ratio of adenine (A) to thymine (T) in DNA is approximately 1:1.

This means that for every adenine molecule, there is a corresponding thymine molecule.

This observation, along with the similar 1:1 ratio of guanine (G) and cytosine (C), forms the basis of Chargaff's rules. 

Explanation

This pathway refers to the movement of water through the cell walls and the spaces between cells, essentially the non-living parts of the plant tissue. 

Explanation

 A semiconductor has electrical conductivity between that of a conductor and an insulator, and silicon falls within this category
