Ethylamine (C2H5NH2) is a primary amine as it has one alkyl group attached to the nitrogen atom.

The zinc-carbon battery is a primary cell, while the others are secondary cells.

The zinc-carbon battery is a type of primary cell, which cannot be recharged.

Phloem is responsible for the transport of food, primarily in the form of sucrose, from the leaves to other parts of the plant.

1-bromobutane is a primary haloalkane as the carbon attached to the halogen is bonded to only one other carbon.

Primary producers, such as plants, convert solar energy into chemical energy through photosynthesis.

The primary structure of proteins refers to the linear sequence of amino acids linked by peptide bonds.

Bt cotton is a genetically modified organism (GMO) that has been engineered to express a bacterial toxin, making it resistant to certain pests.

Microbial fermentation can produce antibiotics, vitamins, and alcohol, among other products.

Photosynthesis produces glucose and oxygen as products, using sunlight, carbon dioxide, and water.

Bacterial cells are prokaryotic, meaning they lack a defined nucleus and membrane-bound organelles.

Bacteria are prokaryotic organisms, which means they lack a defined nucleus and membrane-bound organelles.

A Newtonian fluid has a constant viscosity regardless of the shear rate.

In a parallelogram, opposite sides are equal and parallel, which is a defining property.

All actinides are radioactive, with many being synthetic and unstable.

Addition polymers are formed from unsaturated monomers through addition reactions.

Aldehydes are generally more reactive than ketones due to the presence of the hydrogen atom attached to the carbonyl carbon.

Alkali metals are good conductors of electricity due to their free-moving electrons.

Alkaline earth metals have a higher density than alkali metals.

Alkanes are non-polar molecules and are generally insoluble in water.

Alkenes are unsaturated hydrocarbons due to the presence of at least one double bond.

Alkynes contain at least one triple bond between carbon atoms.

All polygons are defined as closed figures formed by a finite number of line segments.

In a regular polygon, all sides and all interior angles are equal.

Amorphous solids are isotropic, meaning their properties are the same in all directions, unlike crystalline solids.

An identity matrix is always square and has 1s on the diagonal and 0s elsewhere.

An isosceles triangle is defined as having at least two sides that are equal in length.

Aromatic compounds are characterized by a planar structure and exhibit unique stability due to resonance, but they are generally less reactive than alkenes.

Aromatic hydrocarbons contain a benzene ring.

Bases have a bitter taste and turn red litmus paper blue, while acids do the opposite.
