Definition: Relating to a type of chemical compound that is derived from alkanes, which are simple hydrocarbons made up of carbon and hydrogen.

Example: The alkylic compounds are essential in organic chemistry.

Definition: A type of chemical compound that consists of carbon and hydrogen, characterized by having at least one triple bond between carbon atoms.

Example: Acetylene is the simplest alkyne, consisting of two carbon atoms connected by a triple bond.

Definition: A type of mineral that contains silicate and is known for being a source of rare earth metals.

Example: Allanite is often found in metamorphic rocks and is a significant source of rare earth elements.

Definition: Relating to a specific membrane in the developing embryo that helps in waste removal and gas exchange.

Example: The allantoic fluid plays a crucial role in the development of the embryo.

Definition: A thin, membranous sac that forms in the embryos of mammals, birds, and reptiles. It plays a key role in developing the umbilical cord and placenta in mammals.

Example: The allantois plays a crucial role in the development of the embryo by facilitating nutrient and waste exchange.

Definition: A specific version of a gene that is found at a particular place on a chromosome, which can vary among individuals.

Example: Each parent contributes one allele for each gene to their offspring.

Definition: Relating to different forms of a gene that can exist at a specific location on a chromosome.

Example: The allelic variation in the population contributed to the diversity of traits observed.

Definition: A type of gene that can exist in different forms, which can lead to variations in traits among individuals.

Example: The study of allelomorphs helps geneticists understand inheritance patterns.

Definition: A term used in genetics to describe the presence or inheritance of different forms of a gene, known as alleles, that can result in various traits.

Example: The study of allelomorphism is crucial in understanding genetic inheritance patterns.

Definition: A man-made chemical used to kill insects, often found in household sprays and products. It is similar to a natural insect-repelling substance called pyrethrin.

Example: The pest control company recommended using allethrin to eliminate the mosquitoes in the backyard.
