What does it mean for an organism to be heterotrophic?

Back

Heterotrophic organisms obtain nutrients by consuming other organisms or their products, rather than producing their own food through photosynthesis.

Front

What is a desirable trait for transgenic plants?

Back

A desirable trait for transgenic plants is the ability to resist insects, which can enhance crop survival and yield.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment are more likely to reproduce and pass on their traits to their offspring.

Front

What can increase the frequency of genetic mutations in humans?

Back

Increased exposure to X-rays can lead to a higher frequency of genetic mutations in humans.

Front

What happens to a freshwater plant placed in saltwater?

Back

The cells of the freshwater plant will shrink because water will move out of them due to osmosis.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic material, recycling nutrients back into the ecosystem.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the survival of species, as it increases resilience to environmental changes and diseases.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is a transgenic organism?

Back

A transgenic organism is one that has been genetically modified to contain DNA from another species.
