process of copying DNA prior to cell division

Any biotic or abiotic factor that restricts the existence, numbers, reproduction, or distribution of organisms.

Movement of alleles into or out of a population due to the migration of individuals to or from the population

Describes living factors in the environment.

division of the nucleus resulting in 2 daughter cells that are identical to the parent cell; steps are prophase, metaphase, anaphase and telophase

Cell division that produces reproductive cells in sexually reproducing organisms; produces 4 haploid cells that are genetically different

Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms.

A change in the gene pool of a population due to chance

A segment of DNA on a chromosome that codes for a specific trait

thin, flexible barrier around a cell; regulates what enters and leaves the cell

Powerhouse of the cell, organelle that is the site of ATP (energy) production

A molecule containing the genetic information that makes up the chromosomes.

the process whereby the DNA sequence in a gene is copied into mRNA, occurs in the nucleus

type of reproduction in which cells, gametes, from two parents unite to form the first cell of a new organism

A reproductive process that involves only one parent and produces offspring that are identical to the parent.

A relationship in which two different organisms live in close association with each other

The condition describing a non-evolving population (one that is in genetic equilibrium).

loose uncoiled DNA, "Working" DNA

macromolecules containing hydrogen, oxygen, nitrogen, carbon, and phosphorus, DNA and RNA, made up of monomers called nucleotides

Passing of traits from parents to offspring

non-living things in an environment

A group of interdependent organisms inhabiting the same region and interacting with each other

inherited characteristic that increases an organism's chance of survival

process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches; occurs in

chloroplasts

A condition in which both alleles for a gene are fully expressed

A gene the has more that 2 alleles

A cell that contains a nucleus and membrane bound organelles; examples include: protista, fungi, plantae and animalia

A natural process resulting in the evolution of organisms best adapted to the environment based on greater fitness.

change in a DNA sequence that affects genetic information

a single-stranded nucleic acid that contains the sugar ribose that is involved in protein synthesis.

ability to survive and reproduce

Energy-requiring process that moves material across a cell membrane against a concentration difference (low concentration to high concentration)

the action or process of classifying something according to shared qualities or characteristics.

requires oxygen

Tightly coiled DNA that is easily separated during cell division

Population growth that is unhindered because of the abundance of resources for an ever- increasing population.

site of protein synthesis, made up of rRNA and proteins

organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy

Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen; in mitochondria

Movement of individuals into a population

Largest number of individuals of a population that a environment can support

Type of Passive transport using Proteins Movement of specific molecules across cell membranes through protein channels

Selection by humans for breeding of useful traits from the natural variation among different organisms

Energy-rich organic compounds, such as fats, oils, and waxes; that are made of carbon, hydrogen, and oxygen.

A pattern of inheritance in which two alleles, inherited from the parents, are neither dominant nor recessive. The resulting offspring have a phenotype that is a blending of the parental traits.

A part of the cell containing DNA and RNA and responsible for growth and reproduction

Diffusion of water through a selectively permeable membrane using a protein called an aquaporin

a symbiotic relationship in which both species benefit from the relationship, ex. A clownfish lives with a sea anemone both benefiting.

A group of similar organisms that can breed and produce fertile offspring.

A relationship between two organisms in which one organism benefits and the other is unaffected

movement of individuals out of a population

trait controlled by two or more genes

the main source of energy; made up of Carbon, Hydrogen, and oxygen in a 1C:2H:1O ratio; made up of monomerscalled monosaccharides (glucose)

Diffusion that doesn't involve a direct input of energy or assistance by carrier proteins movement of a solute from an area of high concentration to an area of low concentration

the variety of life in the world or in a particular habitat or ecosystem.

Process by which some organisms, such as certain bacteria, use chemical energy instead of light to produce carbohydrates

differences in physical traits of an individual from the group to which it belongs

An interaction in which one organism captures and feeds on another organism

the process in reproduction and growth by which a cell divides to form daughter cells

the study of heredity

Different forms of a gene

the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm; the tRNA brings amino acids to bind their anticodon to the codon on the mRNA at the ribosome, the amino acids are bonded together with peptide bonds

Does not use oxygen, also called fermentation

Growth pattern in which a population's growth rate slows or stops due to limiting factors, following a period of exponential growth

A unicellular organism that lacks a nucleus and membrane-bound organelles examples include: archaebacteria and eubacteria

Definition Structure, storage, defense, transport, and speeding up reactions; Made of monomers: amino acids; Found in hair, muscles, feathers; Common foods: meat, eggs, nuts; Contains Carbon, Hydrogen, Oxygen, and Nitrogen
