Biology Trivia

Front

How much food can your stomach hold at one time?

Back

The human stomach can hold approximately 1800 grams of food at one time.

Front

What is a promoter in genetics?

Back

A promoter is a sequence of DNA at the beginning of a gene that tells RNA polymerase where to start transcription.

Front

What is natural selection based on?

Back

Natural selection is based on genetic variation within populations, the best-adapted individuals leaving the most offspring, and populations producing more individuals than the environment can support.

Front

What is NOT part of Hardy Weinberg law for populations in equilibrium?

Back

Non-random mating is not part of Hardy Weinberg law for populations in equilibrium.

Front

What is FALSE about the Calvin cycle?

Back

The Calvin cycle does not produce carbon dioxide; it uses products from light reactions to produce glucose.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals within a population.

Front

What is the role of RNA polymerase?

Back

RNA polymerase is an enzyme that synthesizes RNA from a DNA template during transcription.

Front

What does it mean for a population to be in Hardy-Weinberg equilibrium?

Back

A population is in Hardy-Weinberg equilibrium when allele frequencies remain constant from generation to generation in the absence of evolutionary influences.

Front

What is the significance of the best-adapted individuals in natural selection?

Back

The best-adapted individuals are more likely to survive and reproduce, passing their advantageous traits to the next generation.

Front

What are the conditions for Hardy-Weinberg equilibrium?

Back

The conditions include a large population, no immigration or emigration, no natural selection, and no genetic mutations.
