Explanation

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

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

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

Explanation

The IUPAC name of iso-octane is 2,2,4-trimethylpentane. 

Explanation

The dual character of matter particles in motion was postulated by De Broglie. 

Louis de Broglie proposed the idea that particles like electrons could behave not only as particles but also as waves, a concept known as wave-particle duality

Explanation

In Bohr's model, electrons occupy specific energy levels around the nucleus.

When an electron moves from a lower energy level to a higher energy level, it absorbs energy

Conversely, when an electron moves from a higher energy level to a lower energy level, it emits energy.

This energy is emitted as a photon of light with a specific wavelength, corresponding to a specific frequency. 

Explanation

The Distribution law controls solvent extraction. 

Distribution law (also known as Nernst's law):

This law states that when a solute is added to two immiscible liquids,

It will distribute itself between the two liquids in a constant ratio,

Regardless of the total amount of solute added.

This ratio is called the partition coefficient. 

Explanation

The constant (often represented as 'k' or 'A') in Charles's Law is dependent on the amount of gas (number of moles) and the pressure.

It essentially represents the proportionality between volume and temperature when pressure is kept constant. 

Explanation

The force of attraction between helium atoms is the London dispersion force. 

Helium is a non-polar noble gas, so the only force of attraction between its atoms is the weak London dispersion force, which arises from temporary fluctuations in electron distribution.
