Physics
An object at rest stays at rest and an object in motion stays in motion, unless...
acted on by an unbalanced force
The theory of continental drift states that all landmasses used to be joined in one supercontinent. What is the name of the supercontinent?
Pangaea
The smallest unit of life
Cells
The basic unit of all matter
Atom
At the top of a roller coaster, the car has stored potential energy. What happens to this energy as the car begins to fall?
The potential energy transforms into kinetic energy.
There are three main types of rock found on Earth. What are they?
Metamorphic, igneous, sedimentary
This cell organelle is the control center of the cell and contains genetic information
Nucleus
The small number that shows the number of a given atom in a molecule
Subscript
You are driving 60 mph in a car and must slam on the breaks to avoid an accident. Although the car has stopped, your body continues to move forward. Why?
Two continental plates form a convergent boundary. What landform or geological feature would you expect to see at this boundary?
A mountain
A gardener has red roses and yellow roses. They want to see if they can create orange roses by cross-pollinating the two plants. What type of reproduction would this be?
Sexual reproduction- using the genetic code from two organisms to create offspring with a unique blend of characteristics
Daily Double: How many atoms of sodium (Na):
2(NaOH)4
8
There are two ways to increase the strength of gravitational pull. What are they?
The closer the distance, the stronger the gravitational pull. The larger the mass, the stronger the gravitational pull.
The tectonic plates ride on top of the mantle like a conveyer belt. Why is the mantle moving?
Heat from the core is creating a convection current in the mantle. As magma rises to the top of the mantle, it begins to cool and sink back down.
Mitochondria are the site of this process in both plant and animal cells, where glucose is broken down into ATP energy. What is the name of this process?
Cellular Respiration
A beaker is filled with sodium hydroxide and placed on a scale Another liquid- copper sulfate- is inside the beaker but hanging over the liquid in a smaller glass. The copper sulfate is dropped into the sodium hydroxide, forming a solid piece of copper hydroxide in the beaker. What evidence is there that a chemical reaction has occurred?
Formation of a solid
To calculate the wavelength of a transverse wave, divide wave-speed by frequency. How can you measure wavelength when looking at a model of a wave?
The distance from trough to trough or crest to crest
New crust is forming along divergent plate boundaries, and yet the Earth is not getting bigger. Why?
While new crust is forming at divergent boundaries, old crust is melting back into the mantle at subduction zones.
Student 1 says that humans use both meiosis and mitosis. Student 2 knows that mitosis is used in asexually reproduction so they think Student 1 is wrong. Who is right?
Student 1 is correct. Human reproduction requires meiosis, but humans also use mitosis in cell repair (example: creating new skin and blood cells.)
Hydrogen and Oxygen are diatomic, which means they cannot exist alone. They must always be bonded to another atom. Knowing this, how can you balance the following equation using coefficient(s):
H2 + O2 --> H2O
2H2 + 02 --> 2H20
