Question 1

Adhesion

Answer 1

When water molecules stick to something else

Question 2

Cohesion

Answer 2

When water molecules stick to each other

Question 3

Surface Tension

Answer 3

When water molecules stick to each other (called cohesion and caused by polarity) to form a “skin” on the surface

Question 4

Polarity (Polar Molecule)

Answer 4

Molecules with opposite charges on either end

Question 5

Universal Solvent

Answer 5

Dissolves many things; if it dissolves in water, then you know it is polar

Question 6

High Specific Heat

Answer 6

Takes a lot of energy to heat up

Question 7

Expands When Frozen

Answer 7

example: potholes

Question 8

Capillary Action

Answer 8

When water moves up tiny passages against the flow of gravity

Question 9

organic

Answer 9

contains carbon

Question 10

inorganic

Answer 10

does not contain carbon

Question 11

monomer

Answer 11

building blocks

Question 12

polymer

Answer 12

many monomers joined together

Question 13

dehydration synthesis

Answer 13

The process of joining monomers (into polymers) by removing water

Question 14

hydrolysis

Answer 14

The process of breaking polymers (into monomers) by adding water

Question 15

Answer 15

C, H, O

Question 16

elements of proteins

Answer 16

C, H, O, N

Question 17

elements of lipids

Answer 17

C, H, O

Question 18

elements of nucleic acids

Answer 18

C, H, O, N, P

Question 19

monomer of carbs

Answer 19

Monosaccharides

Question 20

monomer of proteins

Answer 20

amino acids

Question 21

monomer of lipids

Answer 21

fatty acids/glycerol

Question 22

monomer of nucleic acids

Answer 22

nucleotides

Question 23

function of enzymes

Answer 23

serves as a catalyst for (speeds up) chemical reactions

Question 24

impacts of increasing temperature on enzyme activity

Answer 24

activity increases until a certain point, then becomes denatured and stops

Question 25

impacts of changing pH on enzyme activity

Answer 25

difference from ideal pH makes them work less

Question 26

examples of carbs

Answer 26

Bread, potatoes, glucose, lactose

Question 27

examples of lipids

Answer 27

Fats, oils, waxes

Question 28

examples of protein

Answer 28

Meat, eggs, muscle, organs, blood, hair, nails, enzymes

Question 29

examples of nucleic acid

Answer 29

DNA and RNA

Question 30

functions of carbs

Answer 30

Short term energy storage; plants use for support

Question 31

functions of proteins

Answer 31

Immune protection, structural support, transport, muscle contractions, enzymes, hormones

Question 32

functions of lipids

Answer 32

Long term energy storage; waterproof coverings, cell membranes

Question 33

functions of nucleic acid

Answer 33

Store and transmit hereditary information
