Stimulus

Explain how asexual reproduction is different from sexual reproduction.
Asexual produces offspring identical to parent and requires 1 parent. Sexual produces offspring different from parents and requires 2 parents.
100
What describes this evidence that supports the theory of evolution?
Homologous Structures
100
Describe the difference between biotic and abiotic factors in an ecosystem.
Biotic are living factors, abiotic are nonliving factors.
100
What is the role of a decomposer in a food chain?
They break down dead organisms and return nutrients back into the environment.
200
A substance that contains pathogens that have been weakened or killed but can still trigger the body to produce chemicals that destroy the pathogen.
Vaccine

What are the different forms of a gene called?
(For example R = dominant and r = recessive)
Alleles
200
What is a group of similar organisms that can mate and produce offspring capable of reproduction?
Species

Describe the difference between Immigration and Emigration in relation to a population.
Immigration is when new members move into a population, Emigration is when members leave a population.

What happens to organisms that do not have the adaptations needed to survive a changing environment?
They become extinct.
500
What is the difference between Mutualism and Commensalism?
In mutualism, both organism benefit. In commensalism, one benefits and the other is not affected.
500
Explain how Dr. Francisco Redi helped to disprove the theory of spontaneous generation.
His experiment proved that living things do not appear from nonliving sources (flies don't come from rotting meat, they come from eggs laid on the meat).
