100
These are known as the building blocks of life
What are cells?
100

The metric unit for force (what are forces measured in)

Newtons (N)

100

What do decomposers do?

Organisms that break down tissue and release nutrients back into the ecosystem
100
What are the 3 laws of motion?

Law of Inertia

F=MA

Law of action reaction

100

When looking at an HR Diagram, where are the hottest stars?

on the left

200
This organelle is known as the cell's "powerhouse", breaking down sugars and providing energy to the cell.
What is the mitochondria?
200

A push or a pull

Force

200

What is the bottom level of the food pyramid?

Producers

200
Give an example of how the first law applies in real-life

Seatbelt. 

200

What is subduction? Which plates are involved?

When one plate moves under another (oceanic goes under)

300
This is the process whereby plants turn sunlight, along with carbon dioxide and water, into sugars and oxygen.
What is photosynthesis?
300

The combination of all the forces on an object

Net force

300

What shows the movement of energy through an ecosystem, which way does it go??

The arrows; energy go towards the animal it points at

300

When looking at the third law, why is it that when you sit in a chair, you don't move up or down

Equal and opposite action and reaction

300

What is superposition?

Layers, bottom being the oldest, top being the newest

400
This organ system has the kidneys as its main organ, and allows the body to filter out toxins and release them from the body.
What is the excretory system?
400

When the net force is zero

balanced forces

400

How much energy is transferred from one of the trophic levels to the next?

10%

400
What is inertia? What has more inertia; a fridge or a chair?

An objects resistance to change. 

400
If a mom has blonde hair and a dad has black hair. What color will the hair of the offspring most likely have and why? What or who is responsible for this? 

Black because blonde is a recessive trait. The kid will have black hair because of the traits passed on by parents.

500
While cells are known as the "building blocks of life", this material is known as the "blueprint of life". It is shaped like a double helix, found inside the nucleus, and it allows important characteristics to replicate and be passed on to the next generation.
What is DNA?
500

An object is pushed East (right) with 15 Newtons and pulled East (right) with 13 Newtons. The force of friction is 10N. What is the net force acting on the object?

18 newtons

500

What would happen to an ecosystem if one organism completely died off? (why)

Disrupts ecosystem; flow of energy inconsistent. 

500

Explain a scenario where all 3 laws are applied simultaneously (at the same time)

answer will vary

500

Count the atoms and tell me about the law of conservation of mass/matter. both answers must be correct. 

4C7H5(NO2)3 + 3H2O 

C: 28

H: 26

N:12

O:27

Law of conservation of mass, matter cannot be lost or created.
