Explanation

Aquatic arthropods like crabs, prawns, and some aquatic insects use gills to extract oxygen from water.

Gills provide a large surface area for gas exchange in an aquatic environment.

Explanation

The study of viruses is called virology.

Virology encompasses the study of viruses, their structure, classification, evolution, and how they interact with living organisms.

Explanation

The SI unit of impedance is the ohm (Ω).

Impedance, like resistance, is measured in ohms.

It can be represented as a complex number.

Explanation

Curie (Ci) is a unit that measures the rate of radioactive decay.

1 Curie = 3.7 × 10¹⁰ disintegrations per second.

Explanation

Molarity is calculated by dividing the number of moles of solute by the volume of solution in liters. 

Therefore, the molarity of pure water is approximately 55.56 moles/L, or approximately 55.5 M. 

Explanation

Real gases show deviation from ideal behavior at low temperature and high pressure.

Due to increased intermolecular forces and reduced volume available for gas molecules, which contradicts the assumptions of ideal gas behavior.

Explanation

Coralline red algae are the type of algae that play a role in building coral reefs, along with coral animals.

These algae secrete and deposit calcium carbonate.

It helps to cement the reef structure together.

Explanation

An electric generator works on the principle of electromagnetic induction.

Faraday's law states that a changing magnetic flux induces an emf, which is the working principle of generators.
