GENETICS & INHERITANCE
What is genetics?
The study of how traits are passed from parents to offspring.
What is a gene?
A segment of DNA that determines a specific trait.
What is an allele?
An alternative form of a gene.
What is a dominant allele?
An allele that is expressed even if only one copy is present.
What is a recessive allele?
An allele that is only expressed when two copies are present.
What is a genotype?
The genetic makeup of an organism.
What is a phenotype?
The observable characteristics of an organism.
What is a Punnett square?
A diagram used to predict genetic outcomes of a cross.
,HUMAN BODY SYSTEMS
What is the function of the circulatory system?
To transport oxygen, nutrients, and waste products throughout
the body.
What does the heart do?
It pumps blood around the body.
What is the function of the respiratory system?
To exchange oxygen and carbon dioxide.
What is the role of the digestive system?
To break down food and absorb nutrients.
What is the nervous system responsible for?
Controlling and coordinating body activities.
What is the function of the endocrine system?
To regulate body processes using hormones.
,ECOLOGY
What is ecology?
The study of interactions between organisms and their
environment.
What is a habitat?
The natural environment where an organism lives.
What is a niche?
The role an organism plays in its ecosystem.
What is a trophic level?
A position in a food chain.
What is energy flow in ecosystems?
The transfer of energy from producers to consumers.
What is a limiting factor?
A factor that restricts population growth.
, EVOLUTION
What is natural selection?
A process where organisms with favorable traits survive and
reproduce more.
What is adaptation?
A characteristic that improves survival in an environment.
What is speciation?
The formation of new species over time.
What is variation?
Differences in traits among individuals.
What is survival of the fittest?
Organisms best adapted to their environment are more likely to
survive.
