What is migration in birds?

Back

Migration is the seasonal movement of birds from one region to another, often in response to environmental changes such as temperature and food availability.

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus of eukaryotic cells, where DNA is transcribed into messenger RNA (mRNA).

Front

What are selective pressures?

Back

Selective pressures are environmental factors that influence the survival and reproduction of organisms, leading to natural selection.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some bacteria convert light energy into chemical energy, using chlorophyll to capture sunlight.

Front

How does pH affect flower color in plants?

Back

The pH of the soil can influence the expression of genes responsible for flower color, leading to different colors in flowers based on the acidity or alkalinity of the soil.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem and supporting plant growth.

Front

What is the difference between eukaryotic and prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not have a nucleus and are generally simpler in structure.

Front

What is the significance of chlorophyll in plants?

Back

Chlorophyll is a pigment that allows plants to absorb sunlight for photosynthesis, enabling them to produce their own food.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to variations in traits and may affect an organism's survival.

Front

What is the function of the ribosome in a cell?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.
