Genetics and Traits
This describes an allele that is expressed whenever it is present.
What is dominant?
This is the original source of energy for most ecosystems.
What is sunlight?
This is defined as change in the allele frequencies of populations over time.
What is evolution?
This organelle carries out photosynthesis.
What is chloroplast?
This variable is intentionally changed in an experiment.
What is the independent variable?
This term describes having two different alleles for a trait.
What is heterozygous?
These organisms produce their own food.
What are producers?
This process favors individuals with beneficial traits.
What is natural selection?
This organelle carries out cellular respiration.
What is mitochondria?
This variable is measured in an experiment.
What is the dependent variable?
This is the probability of offspring showing a recessive trait when both parents are heterozygous.
What is 25%?
This happens to consumer populations when producers decrease.
What is consumers decrease?
This describes the organisms most likely to survive in an environment.
What are best adapted organisms?
This happens to glucose production when light is removed.
What is glucose production decreases?
This should be done when experimental results are inconsistent.
What is repeat the experiment?
This explains why a trait can disappear in one generation and reappear in a later generation.
What is a recessive allele?
This happens to prey populations when predators are removed.
What is prey increase?
This must exist in a population for evolution to occur.
What is variation?
This happens to ATP levels when mitochondria fail.
What is ATP decreases?
This must support a scientific conclusion.
What is evidence?
This type of parental cross produces the greatest genetic variation.
What are heterozygous parents?
This trophic level is most affected by energy loss in a food chain.
What are top consumers?
This happens to a population that lacks genetic variation over time.
What is the population struggles to survive?
This process directly provides energy for muscle movement.
What is ATP production?
This should happen when data does not support a hypothesis.
What is revise the hypothesis?
