Force and Motion
What is Newton's 1st law
Whatever is in motion, stays in motion and whatever is at rest, stays at rest.
How many Mutations can a organism possibly go through?
Three (3)
How many seasons does Earth have?
Four (4)
the rapid, periodic back-and-forth or up-and-down motion of an object or particles around a central resting position
Vibration
The lower we go down the ________ the fossils get.
Older
Newton’s Third Law is famous for stating that for every action, there is an equal and opposite ________.
Reaction
These are thread-like structures made of DNA molecules that contain the genes; humans typically have 23 pairs of them.
Chromosomes
This term describes the Moon when the visible illuminated part is "shrinking" or getting smaller.
Waning
This property of a sound wave determines its pitch (how high or low the sound is).
Frequency
This law states that in an undisturbed sequence of sedimentary rock, the oldest layers are at the bottom and the youngest are at the top.
The law of superposition
This force always acts in the opposite direction of a moving object, eventually causing it to slow down.
Friction
This is a specific segment of DNA that codes for a specific trait, such as eye color or hair texture.
Gene
A solar eclipse can only happen during this specific moon phase.
New Moon
If you increase the amplitude of a sound wave, you are making this change to the sound.
Making it louder
This term describes a species that has completely died out and no longer has any living members on Earth.
Extinct
An object travels at a constant speed of 10 m/s for 5 seconds. This is the total distance it traveled.
50 meters
In sexual reproduction, the offspring receive this percentage of their chromosomes from each parent.
50%
It takes the Earth this long to complete one full rotation on its axis.
24 hours
If the waves are bigger, this will be a _______ frequency.
Low
The end of the Mesozoic Era was marked by a mass extinction likely caused by a massive asteroid, which wiped out these famous reptiles.
Dinosaurs (RAWR)
This is the force of attraction between two objects; it depends on the mass of the objects and the distance between them.
Gravity
If you cross two heterozygous tall plants (Tt X Tt), this is the percentage of offspring that will likely be short (tt).
25%
During this event, the North and South Poles are tilted neither toward nor away from the Sun, resulting in equal hours of day and night everywhere. (P.S. Spring and Fall)
Equinox
This is the standard unit used to measure the frequency of a sound wave.
Hertz (Hz)
The fact that 99% of all species that have ever lived on Earth are now extinct is a fact we know primarily because of this.
