100
Changes that occur in the anatomical(physical) structure of an organism and increase the organisms chance of survival.
What are structural adaptations?
100
This includes where an organism lives and what it does there.
What is an organism's niche?
100
Traits that can be passed on either through sexual or asexual reproduction.
What are heritable traits?
100
Traits that show a wide range of possibilities.
What is continuous variation?
100
This type of selection is usually used to increase the amount of food available to human beings.
What is artificial selection?
200
A comparison of the number of species to the total number of organisms in an area.
What is a diversity index?
200
Organisms that live over a wide area that can survive on a variety of food sources.They adapt well to changes in their environment.
What are generalists?
200
Four types of asexual reproduction.
What are binary fission, spores, meristem cells, and budding?
200
Ultra-violet rays, x-rays, and chemicals may cause this to occur.
What is a mutation?
200
This treaty is designed to stop the illegal activity of poachers?
What is the CITES treaty?
300
Biological Indicator species
What is a way other than diversity index for measuring the health of an ecosystem?
300
The symbiotic relationship in which one organism benefits, and one is harmed.
What is parasitism?
300
The fertilized egg containing information from both parents forms this first cell.
What is a zygote?
300
This type of trait will always present itself in the phenotype if it is present in the genes.
What is a dominant trait?
300
Choosing individual characteristics to produce desirable offspring.
What is artificial selection?
400
These are examples of within species differences.
What type of variation is different height and skin color in humans?
400
When resources become scarce, this may occur.
What is competition?
400
This form of reproduction increase species variation and results in a stronger population.
What is sexual reproduction?
400
These cells have 46 chromosomes.
What are somatic cells?
400
This theory explains how the processes of evolution occurs in nature.
What is the theory of natural selection?
500
An owl hunting at night is an example of this.
What is a behavioural adaptation?
500
These organisms tend to have low populations and live in the tropics. They do not adapt well to sudden changes in their environment.
What are specialists?
500
The two ways that fertilization can occur.
What are internal fertilization and external fertilization?
500
This type of cell division in multicellular organisms results in identical offspring.
What is mitosis?
500
The Cane toads in Australia are an example of this?
