What are the two particles found in the nucleus of an atom?

Protons and neutrons.

What is Newton's 1st law of motion?

An object in motion stays in motion and an object at rest stays at rest.

100

What are all living things made up of?

Cells.

100

What is the difference between prokaryotic cells and eukaryotic cells?

Eukaryotes do have membrane-bound organelles, whereas prokaryotes do not.

100

What is the energy criteria of life?

All living organisms extract energy from their surroundings and convert it into a usable form.

200

What is the process where a liquid changes to a gas? Is energy added or removed?

Evaporation. Added.

200

A speeding car travels East for 3 hours and 15 minutes, without being caught. If it covered a distance of 292.5 miles, what was the velocity of the car in mi/hr?

90 mi/hr East

200

What is the purpose of DNA?

It provides instructions for the cell in a code of nucleotide bases.

200

What purpose does the cytoplasm serve?

It is the gel-like substance, in which all of the cell's organelles are suspended.

200

What are the three ways that organisms extract energy?

Autotrophs - Produce their own food.

Heterotrophs - Consume other life.

Decomposers (Saprophytes) - Decompose dead life.

300

Chemical or Physical Change:

Burning a piece of paper.

Chemical.

300

What is the difference between speed and velocity?

Speed does not include direction. Velocity does.

300

All living things sense changes in their surroundings and ______.

Respond to those changes.

300

What do mitochondria do?

They provide energy for the cells.

300

What is the formula for cellular respiration?

Glucose+Oxygen=Water+Carbon Dioxide+ATP Energy
400

What defines an element?

The number of protons (atomic number).

400

What are the six simple machines?

Inclined plane, wheel and axle, lever, wedge, pulley, screw.

400

What is the complement of this DNA sequence?

TGCAAAGGCTC

ACGTTTCCGAG

400

Chloroplasts.

400

What are the four macronutrients and what are their monomers?

Carbohydrates - Monosaccharides

Fats - Glycerol and Fatty Acids

500

What is an example of a third-class lever?

Fishing rod, tweezers, arm, etc.

500

What is homeostasis?

Homeostasis is the process by which the internal environment of a living organism is stabilized.

500

What cellular structures help a plant stay upright? How do they do it?

The cell wall and the central vacuole. The central vacuole fills with water and pushes against the cell wall. This makes all the cells firm and rigid and helps them stand up.

500

What happens in the electron transport system? Where does it occur? Does it use oxygen?

It releases the most ATP out of any part of cellular respiration. It combines hydrogen and oxygen to create water. In the mitochondria. Yes.
