Explanation

Acetylcholine is the neurotransmitter lying outside the central nervous system.

It plays a key role in transmitting signals between nerves and muscles in the peripheral nervous system.

Explanation

GSPC stands for Global Strategy for Plant Conservation.

It is an initiative of the UN’s Convention on Biological Diversity founded in 1999.

It aims to protect plant diversity and reduce plant extinction through five strategic objectives.

Explanation

Porifera is the phylum of sponges, which are multicellular organisms characterized by their porous bodies.

Spongilla is a genus of freshwater sponges, and like all sponges, it belongs to the phylum Porifera.

These organisms are filter feeders, drawing in water through their pores to extract nutrients.

Explanation

Platelets are produced from very large bone marrow cells called megakaryocytes.

As megakaryocytes develop into giant cells,

they undergo a process of fragmentation that results in the release of over 1,000 platelets per megakaryocyte.

Explanation

Explanation

Polysaccharides in plants are synthesized by the process of condensation.

During this process, monosaccharides are joined together through glycosidic bonds.

It releasing water molecules and forming complex carbohydrates like starch and cellulose.

Explanation

During light reactions, PS II receives electrons from the splitting of water.

This process, known as photolysis, generates oxygen, protons, and electrons.

It replenishing the electron supply in Photosystem II.

Explanation

A sarcomere is part of a myofibril between two Z lines.

It is the basic contractile unit of muscle fibers.

It responsible for muscle contraction through the sliding filament mechanism.

Explanation

Mesosomes are the invagination of bacterial cell structure cell membrane.

They are thought to play a role in cellular processes such as cell division and respiration in prokaryotic cells.

Explanation

ATP synthesis through a combination of electrochemical and osmotic events is known as oxidative phosphorylation.

It occurs in the mitochondria during the electron transport chain where a proton gradient is used to drive the synthesis of ATP.
