Across
4.A random change in DNA molecules making up genes that can yield changes in anatomy, physiology, or behavior in offspring.
6.Parts of the fundamental niche of a species that are actually used by that species.
7.Complete disappearance of a species from the earth.
8.Process by which a particular beneficial gene (or set of genes) is reproduced in succeeding generations more than other genes.
11.The full potential range of the physical, chemical, and biological factors a species can use if there is no competition from other species
15.Long-term geographic separation of members of a particular sexually reproducing species.
16.The small genetic changes a population undergoes
18.Separation of populations of a species for long times into different areas.
19.Any genetically controlled structural, physiological, or behavioral characteristic that helps an organism survive and reproduce under a given set of environmental conditions. It usually results from a beneficial mutation.
20.Place or type of place where an organism or population of organisms live.
21.Long-term, large-scale evolutionary changes among groups of species.
22.Skeletons, bones, shells, body parts, leaves, seeds, or impressions of such items that provide recognizable evidence of organisms that lived long ago.
23.Formation of two species from one species because of divergent natural selection in response to changes in environmental conditions.
Down
1.Use of genetically engineered animals to act as biofactories for producing drugs, vaccines, antibodies, hormones, industrial chemicals such as plastics and detergents, and human body organs.
2.Normal extinction of various species as a result of changes in local environmental conditions.
3.Evolution in which two or more species interact and exert selective pressures on each other that can lead each species to undergo various adaptations.
5.Widely accepted scientific idea that all life forms developed from earlier life forms. Although this theory conflicts with the creation stories of many religions, it is the way biologists explain how life has changed over the past 3.6-3.8 billion years and why it is so diverse today.
9.Species with a narrow ecological niche. They may be able to live in only one type of habitat, tolerate only a narrow range of climatic and other environmental conditions, or use only one type or a few types of food.
10.Insertion of an alien gene into an organism to give it a beneficial genetic trait.
12.Formation of the earth and its early crust and atmosphere, evolution of the biological molecules necessary for life, and evolution of systems of chemical reactions needed to produce the first living cells.
13.Species with a broad ecological niche. They can live in many different places, eat a variety of foods, and tolerate a wide range of environmental conditions.
14.Two or more individual organisms of a single species or two or more individuals of different species attempting to use the same scarce resources in the same ecosystem.
17.Chemical or form of radiation that causes inheritable changes in the DNA molecules in the genes found in chromosomes.
