Back

Ee (one dominant allele and one recessive allele)

Front

What is the genotype of a homozygous recessive individual for a trait?

Back

ee (two recessive alleles)

Front

What is the role of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to adaptations.

Front

What is the difference between biotic and abiotic factors in an ecosystem?

Back

Biotic factors are living components (like plants and animals), while abiotic factors are non-living components (like water and temperature).

Front

What is carrying capacity in ecology?

Back

The maximum population size that an environment can sustain indefinitely.

Front

What is the function of the cell wall in plant cells?

Back

The cell wall provides structure and protection to the cell.

Front

What is the primary function of chloroplasts in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy.

Front

What is the significance of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.

Front

What is the process of natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
