Question 8

Atoms

Answer 8

An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons

Question 9

Protons

Answer 9

Positively charged(+), and inside the nucleus(protons and electrons are equal)

Question 10

Neutrons

Answer 10

Neutrally charged(o), and inside the nucleus

Question 11

Electrons

Answer 11

Negatively charged(-), and orbits around the nucleus in orbital shells.

Question 12

Nucleus

Answer 12

The center of the atom with Protons and Neutrons in it

Question 13

matter

Answer 13

Something that takes up space

Question 14

Bonding

Answer 14

Either Sharing or Transferring Electrons

Question 15

Covalent Bonding

Answer 15

Sharing Electrons

Question 16

Ionic Bonding

Answer 16

Transferring Electrons

Question 17

Water

Answer 17

Has Covalent Bonds between water molecules Hydrogen Bonds

Question 18

Adhesion

Answer 18

Sticky to other things (Attraction of water molecules to non water molecules)

Question 19

Cohesion

Answer 19

Sticks to itself (water molecules stick to other water molecules, result of hydrogen bonding)

Question 20

Solutions

Answer 20

consists of the dissolved material called the solute and the dissolving agent called the solvent.

Question 21

Solute

Answer 21

The substance dissolved

Question 22

Solvent

Answer 22

The substance the solute is dissolved in

Question 23

Independent Variable

Answer 29

Controlled/Changed by the experimenter

Question 30

Dependent Variable

Answer 30

A measurable outcome

Question 31

Control

Answer 31

What you are comparing your results to

Question 32

Structure of a water molecule

Answer 32

oxygen atom bound to two hydrogen atoms by covalent bond

Question 33

Why Carbon forms so many different compounds

Answer 33

Carbon atoms can bond with other carbon atoms to form chains and rings

Question 34

Constant

Answer 34

variable kept the same throughout the experiment

Question 35

Cells

Answer 35

collection of living matter enclosed by a barrier that separates the cell from its surrondings, basic uniforms of life

Question 36

Water's Polarity

Answer 36

Has unequal sharing in electrons/protons

Question 37

Cell Structure

Answer 37

This says that 1. all living things are made of cells, 2. cells are the basic unit of structure and function and 3. cells only come from other cells

Question 38

Evolution

Answer 38

The process of change over time
