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.

Meristematic tissue is characterized by its ability to divide and give rise to various types of plant tissues.

Multilayer adsorption is described by the BET theory, which accounts for the formation of multiple layers of adsorbate on the adsorbent.

Nuclear fusion releases energy, requires high temperatures, and occurs in stars, making all options correct.

Nuclear reactions involve large energy changes due to the conversion of mass into energy, unlike chemical reactions.

Organic compounds are primarily characterized by the presence of carbon atoms in their structure.

P-type semiconductors have an excess of holes as majority charge carriers.

Pathogenic microbes are those that can cause diseases in humans, animals, or plants.

Phototropism is the growth of a plant towards light, facilitated by auxins.

Probiotics are beneficial bacteria that promote gut health and are often found in fermented foods.

Prokaryotic cells have circular DNA and lack membrane-bound organelles.

Radioactive decay is a random process, meaning that it cannot be predicted when a particular nucleus will decay.

Sexual reproduction in plants involves the formation of gametes (male and female) and results in genetically diverse offspring.

Sexual reproduction typically involves two parents and results in offspring that are genetically diverse.

When the object is placed between the focal point and the mirror, the image formed by a concave mirror is virtual and erect.

The kingdom Animalia consists of multicellular and heterotrophic organisms.

Monera consists of prokaryotic cells, which are unicellular and lack a defined nucleus.

Plants are characterized by having cellulose in their cell walls.

The kingdom Protista includes both autotrophic and heterotrophic organisms.

Annelida, or segmented worms, are characterized by their segmented bodies.

Echinoderms exhibit radial symmetry in their adult form, which is a defining characteristic of this phylum.
