Explanation
chemical formula of water is H2O

Explanation
Observation Period means, in respect of an Interest Accrual Period.

Explanation
A distinct form or race of a plant or animal species occupying a particular habitat.

Explanation
Previously known as the Malagasy Republic, is an island country in the Indian Ocean .

Explanation
Silverfish eat grains and chew large holes into cloth. They can cause a lot of damage. Ruined items often include stored files, books, and vintage clothes.

Explanation
 Anura: also called Salientia.

Explanation
Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances.

Explanation
chemical formula of water is H2O

Explanation
Observation Period means, in respect of an Interest Accrual Period.

Explanation
The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium. The electrical impulses are generated there.

Explanation
 Some predatory fish include perch, muskie, pike, walleye and salmon etc.

Explanation
Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization.
