What does the notation Tt mean in genetics?

Back

It represents one dominant allele (T) and one recessive allele (t).

Front

What is true about enzymes?

Back

Enzymes are proteins that speed up chemical reactions and are made up of amino acids. They are necessary for biological processes.

Front

Why do leaves float in the photosynthesis floating leaf discs lab?

Back

Leaves float due to the accumulation of oxygen produced during photosynthesis.

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.
