Traits that can be passed on from parent to offspring.

Heritable traits

200

Newton's 2nd law equation.

200

When the earth's umbra falls on the moon, it is called this.

Lunar Eclipse

200

This divides the inner and outer planets

The asteroid belt

200

In order to see an object, light has to hit it and be ___________ from it to our eyes

Reflected

200

Differences in traits within a species.

Variations 

300

Newton's 3rd law of motion.

For every action there is an equal and opposite reaction.

300

The moon phase when the moon is between the Sun and Earth.

New Moon

300

Another name for the 4 outer planets.

Gas Giants

300

The distance from crest to crest on a wave

Wavelength

300

A beneficial trait that helps a species survive and reproduce

Adaptation

400

The acceleration of an object that starts at 25m/s and, 5 seconds later, ends at 100 m/s.

15 m/s/s

400

The season that begins in the southern hemisphere on the June Solstice.

Winter

400

This phase of the star life cycle occurs once all of the hydrogen has been fused into helium.

red giant

400

When light passes from one medium to another, changes speed, and bends.

Refraction

400
3 living species share homologous structures. This must mean they also share a ________.

common ancestor

500

Two friends try and push a 50 kg crate from the same side to see how fast they can get it moving. Friend A pushes with 75 N of force and friend B pushes with 100N of force. Friction resists the motion with 25 N of force in the opposite direction

Find the acceleration.

3 m/s/s

500

Earth has seasons because of these TWO reasons.

Axial tilt and revolution around the sun

500

How we know that the universe is expanding.

Redshift

500

This has to happen for an object to look red in color.

The object absorbs the wavelengths of visible light that are not red and reflects wavelengths of red light.

500

What happens to members of species that are more fit for their environment.

They survive and reproduce at a higher rate, passing adaptations to their offspring.
