1Carbohydrates monomer is [blank_start]monosaccharide[blank_end]. Their polymer is [blank_start]polysaccharide[blank_end]. Their function is for an [blank_start]immediate source of energy[blank_end]. Some examples of carbohydrates are glycogen, which is used to [blank_start]store energy in animals[blank_end], and cellulose, which is used in [blank_start]plant cell walls[blank_end].
- Amonosaccharide
- Bpolysaccharide
- Cimmediate source of energy
- Dstore energy in animals
- Eplant cell walls
2Lipids are made of [blank_start]glycerol[blank_end] and [blank_start]fatty acids[blank_end]. Their function is [blank_start]long term energy storage[blank_end], and [blank_start]they can act as a barrier[blank_end]. Some examples of lipids are oils, [blank_start]waxes, and fats[blank_end].
- Aglycerol
- Bfatty acids
- Clong term energy storage
- Dthey can act as a barrier
- Ewaxes, and fats
3Proteins monomer is [blank_start]amino acids[blank_end]. Their polymer is [blank_start]polypeptide[blank_end]. Their function is [blank_start]maintenance[blank_end], growth, and [blank_start]repair[blank_end]. An example of a protein is [blank_start]enzymes[blank_end].
- Aamino acids
- Bpolypeptide
- Cmaintenance
- Drepair
- Eenzymes
4Nucleic acids monomer is [blank_start]nucleotide[blank_end]. Their polymer is [blank_start]DNA[blank_end] or [blank_start]RNA[blank_end]. Their function is to [blank_start]store and transport genetic information[blank_end]. Examples of nucleic acids include [blank_start]DNA[blank_end] and [blank_start]RNA[blank_end].
- Anucleotide
- BDNA
- CRNA
- Dstore and transport genetic information
- EDNA
- FRNA
5Why are chemical reactions unlikely or slow to happen on their own?
- ABecause enzymes have a very specific shape.
- BBecause the activation energy required for reactions is usually high.
- CBecause there's a very small chance that something will make the reaction without enzymes.
6Enzyme denaturation is, for the most part, irreversible.
- AVerdadeiro
- BFalso
7The more enzymes there are, the [blank_start]faster[blank_end] the reaction will happen.
- Afaster
8Generally, colder temperatures mean [blank_start]slower[blank_end] reactions, and hotter temperatures mean [blank_start]faster[blank_end] reactions. But drastic changes in [blank_start]either[blank_end] temperature will generally [blank_start]denature[blank_end].
- Aslower
- Bfaster
- Ceither
- Ddenature
9Human blood is normally slightly basic. It needs to stay in the range of:
- A8.25 and 8.75
- B6.35 and 6.45
- C7.55 and 7.85
- D7.35 and 7.45
10If blood goes below 7.35, you have [blank_start]acidosis[blank_end]. This is caused by too much [blank_start]acid[blank_end] or carbon dioxide in the blood.
- Aacidosis
- Balkalosis
- Cacid
- Dbiocarbonate
11If blood goes above 7.45, you have [blank_start]alkalosis[blank_end]. This is caused by too much biocarbonate or too [blank_start]little[blank_end] carbon dioxide in the blood.
- Aalkalosis
- Bacidosis
- Clittle
- Dmuch
12What do lungs and kidneys do to maintain homeostasis?
- ARelease carbon dioxide
- BRelease acids
- CRenew cells in the stomach lining
13Kidneys release carbon dioxide faster than the lungs.
- AVerdadeiro
- BFalso
14Drinks like [blank_start]soda[blank_end] filled with [blank_start]acids[blank_end] and [blank_start]sugar[blank_end] damage your tooth enamel, causing lots of problems including the increased likelihood you will need [blank_start]crowns[blank_end].
- Asoda
- Bacids
- Csugar
- Dcrowns
15Stomachs use [blank_start]hydrochloric[blank_end] acids to dissolve and [blank_start]digest[blank_end] food.
- Ahydrochloric
- Bdigest
16In patients with [blank_start]heartburn[blank_end], the [blank_start]pH[blank_end] of the stomach can't [blank_start]renew[blank_end] itself before the [blank_start]acid[blank_end] starts eating through the [blank_start]stomach lining[blank_end].
- Aheartburn
- BpH
- Crenew
- Dacid
- Estomach lining
17Why does plant soil need to stay in a very specific pH range? Choose two options.
- ASo that the plants aren't too acidic or alkaline when people consume them.
- BSo the plants don't take up toxic metals.
- CSo the plants can absorb N, P, and K.
18The [blank_start]independent[blank_end] variable is the thing that you are testing or changing in your experiment. The dependent variable [blank_start]depends[blank_end] on the independent variable. It's the data that you're [blank_start]collecting[blank_end]. The control variable is the thing to [blank_start]compare[blank_end] your experiment to.
- Aindependent
- Bdepends
- Ccollecting
- Dcompare
