CAST Review Practice Questions Set 2

Front

What are the parts of DNA that code for a particular amino acid?

Back

The parts of DNA that code for a particular amino acid are called codons.

Front

What is the relationship between mass and gravitational force?

Back

Both mass and distance are variables that affect the gravitational force between two objects.

Front

Where can genetic mutations occur?

Back

Genetic mutations can occur in the DNA.

Front

Which height above Earth's surface has the highest gravitational potential energy?

Back

3.0 meters has the highest gravitational potential energy.

Front

How can a magnet demonstrate the existence of a magnetic field?

Back

A magnet held near a small metal ball makes the ball roll across a table, showing that a magnetic field exists.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in DNA or RNA that corresponds to a specific amino acid.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is a genetic mutation?

Back

A genetic mutation is a change in the DNA sequence that can lead to changes in traits or functions.

Front

What is the role of distance in gravitational force?

Back

Distance affects gravitational force; as the distance between two objects increases, the gravitational force decreases.
