Diversity & Survival
A feature that help an organism survive and reproduce in its environment.
What is an adaptation?
An organisms role in the environment, includes where an organism lives and what it does.
What is a niche?
The variable we change/ compare
What is the manipulated/ independent variable?
Which shows variation within species
a)skin color in humans
b)both insects and birds can fly
a) skin color in humans
The two levels of taxonomic classification (developed by Linnaeus) that make up an organisms scientific name.
What are genus and species?
Four types of asexual reproduction.
What are binary fission, spores, vegetative reproduction, and budding?
(And parthenogenesis)
The part of the world with the most biological diversity.
What is near the equator
The variable we measure (the results)
What is the responding/ dependent variable?
The symbiotic relationship in which one organism benefits, and one is harmed.
What is parasitism?
Reason why sexual reproduction results in more variation.
What is combining of two sets of DNA
Use a bar graph to show for this type of variation.
What is discrete variation?
which decreases the diversity of a population
a) natural selection
b)asexual reproduction
c)sexual reproduction
b) asexual reproduction
When two gametes join
What is fertilization?
which can be inherited?
a) curly hair
b) a tattoo
c) glasses
d) beard
curly hair
A forest contains wolves, deer, spruce trees, insects, fungi, birds, and many other organisms.
A student says, "All of these organisms together are a population."
Why is the student incorrect?
What is "all of these organisms are part of a community"?
This famous scientist developed the theory of evolution by natural selection after sailing on the HMS Beagle.
Who is Charles Darwin?
On the Galápagos Islands, these famous birds demonstrated niche partitioning as different species evolved unique beak shapes to specialize in eating seeds, insects, or cactus flowers.
What are Darwins Finches?
when an ameoba splits in half to form two ameobas this is called?
Binary Fission
when peppered moths were mostly white because they needed camouflage on the white birch trees of London then turned mostly black over a period of 10 years because the trees in London became blackened with pollution.This is an example of what processes.
What is natural selection
A disease kills most of the plants in a meadow. Several herbivore species then decline, followed by a decline in predator populations.
What does this demonstrate about the relationship between organisms and their environment?
Species are dependent on one another and on their environment; a change affecting one population can affect many others.
