What is an isotonic solution?

Back

An isotonic solution is a solution that has the same concentration of solutes as another solution, resulting in no net movement of water across a semipermeable membrane.

Front

What happens to a cell in an isotonic solution?

Back

In an isotonic solution, a cell maintains its shape and size because the concentration of solutes inside the cell is equal to that outside the cell, leading to no net movement of water.

Front

What is the relationship between rainfall and rabbit populations in an ecosystem?

Back

Increased rainfall can lead to more grass and seeds, which can support a larger rabbit population, potentially increasing the populations of their predators, like hawks and coyotes.

Front

What is the principle of natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring, leading to evolutionary changes over time.

Front

What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species, often due to genetic variation and environmental factors.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population, which can lead to different traits and adaptations.

Front

What are limiting factors in an ecosystem?

Back

Limiting factors are environmental conditions that restrict the growth, abundance, or distribution of an organism or a population of organisms.

Front

What is the significance of Darwin's studies on Galapagos finches?

Back

Darwin's studies on Galapagos finches demonstrated how species can evolve through natural selection, adapting to different environments and food sources.

Front

What is the effect of overpopulation on microbial populations?

Back

Overpopulation can lead to a decrease in microbial populations as resources become limited, resulting in competition and higher mortality rates.

Front

What is the role of predators in an ecosystem?

Back

Predators help control the population of prey species, maintaining a balance in the ecosystem and promoting biodiversity.
