Homozygous is when an organism has either both dominant alleles or both recessive alleles.
True
False
When two objects collide, a force is exerted on each object. The two forces are _____.
dependent on the mass
in the same direction
of equal strength
greater on the object with more mass
Light carries energy that can cause materials to change.
True
False
The sex cell(s) created through meiosis are _______.
muscle cells
egg cells
sperm cells
heart cells
When a bumper car carrying a person with more mass collides with a bumper car carrying a person with less mass, what happens?
The person will less mass will experience a weaker force.
The person with more mass will move father after the collision.
The person with more mass will experience a stronger force.
The person with less mass will move farther after the collision.
In order for an object to speed up, the direction of the force is:
in any direction
in the same direction as the object's motion
in the opposite direction of the object's motion
In order for an object to stop moving, the force must come from
the same direction as the object's motion
the opposite direction as the object's motion
any direction.
If the same strength force is exerted on two objects with different masses
the object with more mass will have a greater change in velocity
the object with less mass will have a greater change in velocity
Object A is traveling to the right at 5 cm/s. Object B is not moving (0 cm/s). They both have the same mass. When they collide . . .
the forces will be different strengths and in the opposite direction
the forces will be the same strength and in the opposite direction
the forces will be the same strength in the same direction
the forces will be different strengths in the same direction
What are the five ways an object's motion can change?
start, stop, speed up, slow down, hit something
force, friction, mass, velocity, speed
start, stop, change direction, speed up, slow down
none of the above (there are only 4 ways)
The area of magnetic force around a magnet is known as its _____________.
Magnetic Field
Magnetic Fan Lines
Magnetic Area
Magnetic Location
Which move will result in the greatest potential energy increase?
Moving the cart on Track 1 one space to the right.
Moving the cart on Track 2 one space to the left.
Moving the cart on Track 2 one space to the right.
All moves will result in the same increase in potential energy.
What happens to the energy in a system of magnets when the magnetic force causes two magnets to move?
The potential energy in the system increases.
The kinetic energy in the system decreases.
Some of the potential energy is converted to kinetic energy.
Some of the kinetic energy changes to potential energy.
What is kinetic energy?
The energy that is stored in an object or system
To push objects away from each other
The energy that an object has because it is moving
To move from one object to another
What is potential energy?
The energy that an object has because it is moving
The energy that is stored in an object or system
To provide evidence against a claim
One of the two opposite ends of a magnet
When a material absorbs energy from light,
the energy causes the material to cool down.
there is no effect on the material.
the energy causes the material to heat up.
the energy causes the material to change.
The taller the amplitude, the less energy a light wave has.
true
false
The number of waves that pass in a second describes a waves ___
wavelength
wave speed
amplitude
frequency
These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?
Yes. Laser 2 could be giving off a different type of light because Laser 2 has a different wavelength than Lasers 1 and 3.
Yes. Laser 3 could be giving off a different type of light because Laser 3 has a different amplitude than Lasers 1 and 2.
No. All three lasers must be giving off the same type of light because all three are lasers.
Which of the following is an example of incomplete dominance?
A red cow and a white bull have a red and white spotted calf.
Human ABO blood types
A red flowering plant and a white flowering plant have pink flowered offspring.
A tall plant and a short plant have tall offspring.
Every living thing has genetic information stored in the form of
Ribosomes
DNA
Chloroplast
Mitochondria
