Semester 1 finals review

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which electromagnetic wave has the highest frequency?

Back

Ultraviolet (UV) waves have the highest frequency among the options provided.

Front

What determines the characteristics of a pea plant's seeds?

Back

The characteristics of a pea plant's seeds, such as smooth or wrinkled, are determined by the information present in chromosomes in the nucleus.

Front

What is the relationship between action and reaction forces?

Back

For every action, there is an equal and opposite reaction. For example, when a basketball bounces, the gym floor pushes up on the ball with equal force as the ball pushes down on the floor.

Front

What is the primary function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA into proteins.

Front

What is wavelength in the context of electromagnetic waves?

Back

Wavelength is the distance between successive crests of a wave, and it determines the type of electromagnetic radiation.

Front

What is the role of chromosomes in heredity?

Back

Chromosomes carry genetic information that determines traits and characteristics passed from parents to offspring.

Front

How do gravity and normal force interact when a ball bounces?

Back

When a ball bounces, the normal force from the ground acts upward against the force of gravity acting downward.

Front

What is the difference between frequency and wavelength?

Back

Frequency is the number of waves that pass a point in one second, while wavelength is the distance between successive waves.

Front

What is the function of the plasma membrane in a cell?

Back

The plasma membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
