Force and Motion
This Newton's Law explains why a swimmer pushes off against a wall to go the opposite direction.
What is Newton's Third Law?
If the reactants are what react in a chemical equation, these are the things that are produced.
What are products?
All of the genetic information in a cell is shared with this three-letter acronym.
What is DNA?
The healthier of two ecosystems will probably have more of this, meaning a wide variety of life.
What is biodiversity?
This is the name of the chart that is used to sort stars into categories based on their temperature and luminosity.
What is the H-R Diagram?
According to the Second Law of Motion, a 2 kg ball rolled with a Force of 10 Newtons will have this much acceleration.
What is 5 m/s2?
This is the number of total atoms present in H2O.
What is three?
One of the two organelles that a plant cell has that an animal cell lacks.
What is the cell wall?
OR
What are chloroplasts?
A FACTOR that LIMITS the number of organisms that can live in an ecosystem is called this.
What is a limiting factor?
The majority of stars on the H-R Diagram are located in this group, which usually runs from the top left to the bottom right corner.
What is the Main Sequence?
"An object at rest will stay at rest" is a major component of this one of Newton's Laws of Motion.
What is the First Law of Motion?
I can represent iron rusting like this:
4Fe + 3O2 --> 2Fe2O3
I am not sure, however, if I wrote that correctly. I would know the answer if my numbers are correct, meaning that the equation is this...
What is balanced?
This organelle controls what can enter and exit a cell.
What is the cell membrane?
An energy pyramid will always have these types of organisms at the base or bottom.
What is a producer?
Stars begin their lives in this stage where gas and dust clump together but light and heat are not yet produced.
What is a nebula?
When calculating the force that is being used to push an object along the floor, you subtract the frictional force from the applied force. That number will give you this.
What is the net force?
In the chemical formula for C6H12O6, you'd find this many atoms that AREN'T Carbon.
What is 18?
Help! I'm stuck in this jelly-like substance inside the cell.
What is the cytoplasm?
In a food web, the arrows represent this.
What is the flow of energy?
This factor determines whether a star ends its life as a white dwarf or a black hole.
What is the star's mass?
If a rocket with a mass of 100 kg was shot into the air with an acceleration of 10 m/s2, it would have this much force when it collided with its target.
What is 1000 Newtons?
The chemical reaction in a bag formula was this, I think:
CaCl₂ + 2NaHCO2 → CaCO₃ + 2NaCl + H₂O + CO₂
Can you check to see if my numbers are correct? That way, you can tell if the equation is balanced or unbalanced...
What is unbalanced?
These organelles are responsible for the energy my cells produce during cellular respiration.
What are mitochondria?
Pioneer species such as lichens and mosses are always necessary for this process that kicks off life in a new ecosystem?
What is primary succession?
Help! I'm looking at a galaxy that is definitely not elliptical or spiral. It must be this type of galaxy that has an unusual shape.
What is irregular?
