What is the region around a magnet where its magnetic influence is felt known as?
Magnetic field
100
What is the process called when DNA makes copies of itself?
Replication
100
What happens to the strength of the magnetic field when the distance from a magnet is increased?
The strength decreases
100
In which medium does sound travel the fastest?
Solid
200
force that resists the sliding or rolling of one solid object over another. Ex: sandpaper on a block of wood.
Friction
200
What happens to the strength of an electromagnet when more coils of wire are added to it?
The strength increases
200
How many PAIRS of chromosomes do humans typically have?
23 pairs
200
DNA is tightly coiled and packaged into structures called
chromosomes
200
At what point does a roller coaster have the greatest amount of kinetic energy?
bottom of a hill
300
What is Newton's first law of motion also known as?
The law of inertia
300
Which property of a sound wave determines its pitch?
Frequency
300
What is the term for when the DNA strand unzips itself and builds a complementary RNA strand. Is is the first step in protein synthesis.
Transcription
300
If a sound wave has a large amplitude, what does this mean about the sound?
It is loud
300
Why is Earth's magnetic field important for navigation?
It allows compasses to work
400
speed and direction of an object.
velocity
400
What happens to the poles of an electromagnet when the direction of current flow is reversed?
The north pole becomes the south pole and vice versa
400
This step occurs at the ribosome in the cytoplasm. Codons are read in groups of three and the tRNA brings the correct amino acid.
Translation
400
the differences in DNA sequences between individuals within a population or between populations of the same species.
genetic variation
400
What type of wave is a sound wave?
Longitudinal wave
500
Which law does this picture show
Newton's Third Law

Why are high-frequency electromagnetic waves generally more dangerous than low-frequency waves?
They carry more energy
