Classification of Living Things — Cumulative exam Answers

The gravitational force between two asteroids is 6.2 × 108 N. Asteroid Y has three times the mass of asteroid Z.

Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been nicknamed the “fishapod” because it is believed to be a species had traits of both fish and tetrapods, the first four-legged animals.Which evidence would scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae?

What is the Milky Way?

Whose data did Kepler use to construct the laws of planetary motion?

The orbital period of a satellite is 2 × 106 s and its total radius is 2.5 × 1012 m. The tangential speed of the satellite is m/s. (Round to the nearest whole number, do not add any punctuation.)

What force acts between Earth and the moon?

Which is a factor that keeps Earth in orbit around the Sun?

A large atom decays and emits a particle. After the reaction is complete, the atom’s mass has changed substantially. What kind of particle has most likely been emitted?

A 2-column table with 4 rows. The first column labeled wave has entries W, X, Y, Z. The second column labeled Observations has entries its motion is perpendicular to wave motion, its particles move up and down, its particles only move small amounts, its motion is parallel to wave motion.

Which landform is part of the cryosphere?

The waves created by two speed boats in a lake interact to form larger waves. This is an example of

Which particles that make up an atom are involved in nuclear reactions?

Which is a type of star system?

Levi observed properties of three different waves and recorded observations about each one in his chart.

Which type of star will become a black hole when it dies?

Which causes objects in the universe to resist a change in speed or direction?

A relationship exists between gravity, mass, and distance. The greater the mass of the objects, the greater the gravitational force between them. The greater the distance between the objects, the weaker the gravitational force between them.

Which remains the same as the distance of an object from Earth changes?

What term describes the moon’s path around Earth?

About how old is the Sun?
