What is a Punnett square?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Front

What determines the type of specialized cell produced from a stem cell?

Back

The genes that are expressed in the daughter cell determine what type of specialized cell will be produced.

Front

Why is scientific naming important in biology?

Back

Each scientific name applies to only one species, making it universally identifiable to scientists.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide during photosynthesis, reducing its concentration in the atmosphere.

Front

What is active transport in cellular biology?

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy from ATP.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.

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 cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is a stem cell?

Back

A stem cell is a unique type of cell that can differentiate into various specialized cell types and can self-renew.

Front

What is the significance of genetic variation?

Back

Genetic variation is important for the survival of a species as it allows for adaptation to changing environments.
