Explanation

Potassium ferrocyanide ​ [K[Fe(CN) 6] is an example of a complex salt

Because it contains a central metal atom (iron) bonded to ligands (cyanide ions)

Explanation

In solids, particles mainly exhibit vibrational motion about their fixed positions.

They have limited translational and rotational motion compared to liquids and gases.

Explanation

In the dark reaction (also known as the Calvin cycle), the first stable compound formed is 3-phosphoglyceric acid (3-PGA), which is a three-carbon compound.

Hence, the correct answer is c) 3. 

Explanation

 Ostia are small pores on the sponge's body that allow water to flow in, leading to the central cavity called the spongocoel. 

Explanation

Most coenzymes are actually vitamins or derived from vitamins, meaning they are essential organic compounds needed in small amounts for normal metabolism

Explanation

When a soap bubble is charged, the repulsive forces between like charges on the surface of the bubble cause the bubble to contract, decreasing its size.

Explanation

Cilia and flagella have a characteristic "9+2" arrangement of microtubules: nine outer pairs and two central single tubules.

Explanation

A carbocation is a carbon atom with a positive charge attached to three other atoms or groups.

Explanation

 In Einstein's universe, the fourth dimension is time. 

Einstein's theory of relativity revolutionized our understanding of space and time, merging them into a single four-dimensional continuum called "spacetime".

Time is considered the fourth dimension within this framework. 

Explanation

Ohm × Farad is equivalent to a second (s).

This is because the unit of capacitance (Farad)

multiplied by resistance (Ohm) gives time (s),

which represents the time constant in RC circuits.
