Viruses have a protein coat (capsid) and lack cellular structure and metabolism, requiring a host to reproduce.

A diode allows current to flow in one direction only, making it a unidirectional device.

A good cloning vector should have a high copy number to ensure that multiple copies of the inserted gene are produced within the host cell.

A reversible cell can be recharged, allowing it to be used multiple times.

Semiconductors have zero conductivity at absolute zero and their conductivity increases with temperature.

High biodiversity is a characteristic of a stable ecosystem, as it enhances resilience and stability.

A Zener diode is designed to operate in reverse bias and maintain a constant voltage.

Addition polymers are formed from monomers that contain double bonds, which open up to form long chains.

Algae are primarily autotrophic organisms that can perform photosynthesis.

The ability to respond to stimuli is a characteristic of all living organisms, allowing them to interact with their environment.

Aromatic hydrocarbons are known for their pleasant smell and contain a stable ring structure.

Asexual reproduction produces genetically identical offspring from a single parent.

Brittle materials fracture without significant deformation.

Bryophytes are typically found in moist habitats and do not have true roots, xylem, or phloem.

Complete flowers have all four whorls: sepals, petals, stamens, and carpels.

Cross-linked polymers have a three-dimensional network structure, which gives them a high melting point and strength.

Dicots are characterized by having net-like leaf venation and two cotyledons.

Dicotyledons are characterized by having two cotyledons in their seeds.

Elastic materials return to their original shape after the removal of the applied force.

Essential amino acids cannot be synthesized by the body and must be obtained through the diet.

Essential oils are volatile compounds that are often used for their aromatic properties and therapeutic benefits.

Ethers generally have lower boiling points than alcohols due to the absence of hydrogen bonding.

Eukaryotic cells are characterized by the presence of membrane-bound organelles, including a nucleus.

Eukaryotic genes often contain introns, which are non-coding sequences that are removed during RNA processing.

GMOs are organisms whose genetic material has been altered using genetic engineering techniques, often incorporating genes from other species.

Gibberellins promote flowering and are also involved in seed germination and stem elongation.

Ionic solids are characterized by high melting points due to the strong electrostatic forces between the ions.

Isomers have the same molecular formula but different structural or spatial arrangements.

The ability to evolve is a characteristic of life, allowing organisms to adapt to their environment over generations.

Living organisms can evolve over time, which is a fundamental characteristic of life.
