16
Q

What is a suspension?

A

When the particles are bigger than the water molecules so it doesn’t dissolve

17
Q

What is a colloid

A

A colloid is when the particles are smaller than suspensions butt bigger than a solute

18
Q

What is the main difference between a colloid and suspensions/solutions

A

A call Lloyd takes in the water and a solution/suspension tries to take things into the water

19
Q

Draw the pH scale and show which numbers are acids bases and neutrals

A

At the top is the number one it is an acid in the middle it is the number seven it is neutral at the bottom it is number 14 and it is base

20
Q

What ions are in an acidic solution

A

H plus

21
Q

What ions are in a base solution

A

OH minus

22
Q

What are the four major organic compound groups

A

Nucleic acid’s, proteins, carbohydrates, lipids

23
Q

What is the monomer of a carbohydrate

A

Monosaccharide a.k.a. one unit of sugar

24
Q

Define monosaccharide disaccharide and polysaccharide

A

Mono equals one unit of sugar die equals two units of sugar poly equals many units of sugar

25
Q

What to sugars are isomers and Why

A

Glucose and fructose because they have the same number of Adams and different structures

26
Q

Which organic compound group has fats waxes and phospholipids

A

Lipids

27
Q

Draw and label the phospholipid

A

Two circles the things in between the two is a cell membrane the smaller things in between the two a.k.a. the two lollipops one of the soccer parts is glycerol the others phosphate in the sticks are fatty acids

28
Q

What is the monomer of a protein

A

An amino acid

29
Q

What is the “racecar protein” and why

A

Enzymes because it speeds up reaction time

30
Q

Can an enzyme be reused

A

Yes

31
Q

What organic COM phone group are DNA and RNA from

A

Nucleic acid’s

32
Q

Is DNA the message or the messenger

A

Message

33
Q

What is the difference between where DNA is found in the cell and where RNA is found in the cell

A

DNA is in the nucleus, and RNA is in the cytoplasm

34
Q

What chemical reaction forms a molecule of water on the bond site

A

A condensation reaction

35
Q

What is a “water splitting” breakdown reaction called

A

Hydrolysis

36
Q

What is the bond formed between amino acids called

A

Peptide bond

37
Q

What are two, and three or more amino acids called

A

Dipeptide, polypeptide

38
Q

What is the test called that causes a color change

A

An indicator test

39
Q

What does soluble mean

A

Able to dissolve

40
Q

What does translucent mean

A

Able for light to come through

41
Q

Name three reasons why water is so special and therefore a compound found in all living things

A

Water is constantly forming (condensation reaction), water is the universal solvent, through hydrolysis, things are split down into H2O
