●● Dependent Variable
Answer: The variable that is measured and affected in an experiment,
responding to changes in the independent variable.

Answer: Conditions in an experiment that are kept constant to ensure
that any changes observed are due to the independent variable.
●● Composition of Blood
Answer: Blood is composed of red blood cells, white blood cells,
platelets, and plasma, each serving specific functions in the body.
●● Structure of DNA
Answer: DNA is a double helix made of nucleotides, which store and
