Bacteria
Single-celled prokaryotic organisms that can live almost anywhere.
What are bacteria?
Tiny infectious particles that require a host cell to reproduce.
What are viruses?
The study of interactions between organisms and their environment.
What is ecology?
Organisms that make their own food through photosynthesis.
What are producers?
A group of individuals of the same species living in the same area.
What is a population?
Bacteria reproduce through this asexual process.
What is binary fission?
The part of a virus that attaches to a host cell and contains genetic material.
What is the capsid and viral genome?
A group of interacting populations living in the same area.
What is a community?
Organisms that eat other organisms for energy.
What are consumers?
The total collection of all alleles in a population.
What is a gene pool?
Name two ways bacteria can be beneficial to humans.
What is helping with digestion and producing vitamins or fermenting food?
Explain why viruses are not considered living organisms.
What is they cannot reproduce or carry out metabolism without a host cell?
The part of Earth where life exists.
What is the biosphere?
Organisms that break down dead material and recycle nutrients.
What are decomposers?
The process by which individuals with advantageous traits survive and reproduce more successfully, changing allele frequencies over time.
What is natural selection?
Predict what might happen if all beneficial bacteria in humans were eliminated.
What is digestion and nutrient absorption would be impaired, and harmful bacteria could overgrow?
The viral reproduction cycle in which the virus immediately makes copies and destroys the host cell.
What is the lytic cycle?
A group of individuals of the same species living in one area.
What is a population?
The diagram showing who eats whom in an ecosystem.
What is a food chain?
A random change in allele frequencies due to chance events, especially in small populations.
What is genetic drift?
Explain why antibiotics can kill bacteria but not viruses.
What is antibiotics target bacterial cell structures or metabolism, which viruses lack?
How do vaccines help prevent viral infections?
What is they stimulate the immune system to recognize and respond to a virus without causing disease?
Predict what might happen to a population if its ecosystem exceeds its carrying capacity.
What is the population could decline due to lack of resources, disease, or increased competition?
Explain why energy decreases at each trophic level.
What is energy is lost as heat during metabolic processes, so less energy is available to the next level?
Explain why evolution occurs in populations rather than individuals.
What is individuals do not change their genes during their lifetime, but allele frequencies in a population change over generations?
