Biology is the scientific study of living organisms, encompassing various sub-disciplines such as zoology and botany.

Biodiversity refers to the variety of life in the world or in a particular habitat or ecosystem.

Physisorption is characterized by a low heat of adsorption, typically less than 40 kJ/mol, due to weak van der Waals forces.

The reaction of ammonia with an alkyl halide primarily forms a primary amine.

The reaction of ammonia with an alkyl halide initially forms a primary amine.

Enzymes are primarily proteins that catalyze biochemical reactions.

DNA is classified as a nucleic acid, which stores and transmits genetic information.

A covalent bond is formed when two atoms share electrons.

Alkynes contain at least one triple bond between carbon atoms.

Alkenes are characterized by the presence of at least one double bond between carbon atoms.

Organic compounds primarily consist of covalent bonds formed between carbon and other atoms.

A peptide bond links amino acids in proteins.

In n-type semiconductors, electrons are the predominant charge carriers.

In n-type semiconductors, the majority charge carriers are electrons.

Tendons are connective tissues that connect muscles to bones, allowing for movement.

Adipose tissue is a type of connective tissue that stores fat and provides insulation and cushioning.

Diamond crystallizes in a cubic crystal system, specifically in a face-centered cubic lattice.

Beta decay involves the conversion of a neutron into a proton, emitting a beta particle (electron).

Beta plus decay involves the conversion of a proton into a neutron, emitting a positron.

Stratified squamous epithelium is designed to protect underlying tissues in areas subject to abrasion.

Ciliated columnar epithelium is found in the lining of the respiratory tract, where it helps to trap and move particles out of the airways.

Columnar epithelial tissue is found in the lining of the stomach.

Simple columnar epithelium is specialized for absorption and secretion, commonly found in the intestines.

When the object is placed beyond 2F, the image formed by a convex lens is real, inverted, and smaller than the object.

Parasitism is a type of interaction where one organism benefits at the expense of another.

Competition occurs when two species vie for the same limited resources, which can negatively impact both species.

Structural isomerism occurs when compounds have the same molecular formula but different structural arrangements.

CH3NH2 (methylamine) and C2H5NH2 (ethylamine) exhibit structural isomerism as they have different carbon skeletons.

The complex [Co(en)2Cl2]+ can exhibit optical isomerism due to the presence of bidentate ligands (en = ethylenediamine) which can create non-superimposable mirror images.

The complex [Cr(en)3]3+ shows optical isomerism because it contains bidentate ligands (en = ethylenediamine) that can create non-superimposable mirror images.
