What is homeostasis? In your answer, provide 2 different examples.
Maintaining a stable internal environment. 2 examples are body fluids (fluid homeostasis) and body temperature (temperature homeostasis).
What is the biological significance of mutation?
Evolution
What is the biological significance of mutation?
Cells, tissues, organs, organ systems, organism.
What is the basic building block of organisms?
Cells

What is a karyotype and what information does it give?
It sorts the chromosomes by size and determines if there is an error (increased or decreased chromosome number).
alleles are the same

alleles are different
Heterozygous
the stronger form of a gene
Dominant

makes own food from sunlight.
Autotrophic
consumes food through eating or absorption.
Heterotrophic
first level in the food chain -makes food form sunlight.
Producer
eats producers or other consumers
Consumer
eats dead or decaying matter.
Decomposer
humans chose the parents.
Selective Breeding
survival of the fittest.
Natural Selection
new species are created through pressure and mutation.
Speciation
early developmental evidence of common ancestor
Embryonic development evidence
