Pregunta 1
Pregunta
Carbohydrates 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].
Pregunta 2
Pregunta
Lipids 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].
Pregunta 3
Pregunta
Proteins 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].
Respuesta
-
amino acids
-
polypeptide
-
maintenance
-
repair
-
enzymes
Pregunta 4
Pregunta
Nucleic 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].
Pregunta 5
Pregunta
Why are chemical reactions unlikely or slow to happen on their own?
Respuesta
-
Because enzymes have a very specific shape.
-
Because the activation energy required for reactions is usually high.
-
Because there's a very small chance that something will make the reaction without enzymes.
Pregunta 6
Pregunta
Enzyme denaturation is, for the most part, irreversible.
Pregunta 7
Pregunta
The more enzymes there are, the [blank_start]faster[blank_end] the reaction will happen.
Pregunta 8
Pregunta
Generally, 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].
Respuesta
-
slower
-
faster
-
either
-
denature
Pregunta 9
Pregunta
Human blood is normally slightly basic. It needs to stay in the range of:
Respuesta
-
8.25 and 8.75
-
6.35 and 6.45
-
7.55 and 7.85
-
7.35 and 7.45
Pregunta 10
Pregunta
If 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.
Respuesta
-
acidosis
-
alkalosis
-
acid
-
biocarbonate
Pregunta 11
Pregunta
If 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.
Respuesta
-
alkalosis
-
acidosis
-
little
-
much
Pregunta 12
Pregunta
What do lungs and kidneys do to maintain homeostasis?
Pregunta 13
Pregunta
Kidneys release carbon dioxide faster than the lungs.
Pregunta 14
Pregunta
Drinks 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].
Pregunta 15
Pregunta
Stomachs use [blank_start]hydrochloric[blank_end] acids to dissolve and [blank_start]digest[blank_end] food.
Pregunta 16
Pregunta
In 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].
Respuesta
-
heartburn
-
pH
-
renew
-
acid
-
stomach lining
Pregunta 17
Pregunta
Why does plant soil need to stay in a very specific pH range? Choose two options.
Respuesta
-
So that the plants aren't too acidic or alkaline when people consume them.
-
So the plants don't take up toxic metals.
-
So the plants can absorb N, P, and K.
Pregunta 18
Pregunta
The [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.
Respuesta
-
independent
-
depends
-
collecting
-
compare
