Biology Concepts

Natural Selection

• The process through which organisms with advantageous traits are more likely to survive and reproduce, leading to the gradual evolution of a species.

• A method of breeding plants and animals for specific traits.

• The random changes in the genetic makeup of a population over time.

• The theory that all species are unchanging and fixed.

Heritable Trait

• A characteristic or feature that can be passed from parents to offspring through genes.

• A trait that is only acquired during an individual's lifetime.

• A feature that is determined solely by environmental factors.

• A characteristic that cannot be observed in offspring.

Acquired Trait

• A characteristic inherited from parents through genetics.

• A feature that develops after birth due to environmental influences.

• A trait that is present at birth and does not change over time.

• A genetic mutation that occurs during an organism's lifetime.

Trait

• A specific characteristic or feature of an organism, which can be physical, behavioral, or biochemical.

• A type of genetic mutation that affects an organism's appearance.

• A method of reproduction in plants and animals.

• A classification system for different species of organisms.

Probability

• The measure of how likely an event is to occur, expressed as a fraction, decimal, or percentage.

• A method of predicting future events based on past occurrences.

• The total number of possible outcomes in a given situation.

• The certainty that an event will not happen.

Protein

• A small molecule that provides energy to cells.

• A large, complex molecule made up of amino acids that performs various functions in the body, including supporting structure, regulating processes, and facilitating chemical reactions.

• A type of carbohydrate that stores energy in the body.

• A lipid that is essential for hormone production.

Distribution

• The way in which a particular trait or characteristic is spread out or arranged across a population or geographical area.

• The process of collecting data from a sample population.

• The method of analyzing the frequency of traits in a population.

• The technique used to visualize data on a map.

Species

• A group of living organisms that can interbreed and produce fertile offspring, sharing common characteristics.

• A classification of organisms based solely on their habitat.

• A collection of organisms that are all genetically identical.

• A term used to describe any living organism, regardless of its characteristics.

Gene

• A segment of DNA that contains the instructions for building proteins and determining specific traits in an organism.

• A type of RNA that helps in protein synthesis.

• A structure that carries genetic information in the form of chromosomes.

• A molecule that catalyzes biochemical reactions.

Mutation

• A change in the DNA sequence of a gene, which can lead to variations in traits and may affect an organism's characteristics.

• A process that occurs only in bacteria and viruses.

• An irreversible change in an organism's environment.

• A method of reproduction in plants.
