1. carbohydrates and fats both
a. can be used as an energy source by organisms
b. can be bonded together to construct dna molecules
c. are made up of the glucose monomer
d. are monomers that can be made into large polymer chains

2. enzymes are proteins that speed up reactions by (2 points)
a. providing an additional energy source
b. supplying additional molecules for the reaction
c. removing inhibitors that slow down reactions
d. lowering the amount of energy required

1. Carbohydrates and fats both - can be used as an energy source by organisms.

Carbohydrates provides quick energy while fats are stored energy. If there is no sufficient carbohydrates to provide energy, then the stored fats come to use.

2. Enzymes are proteins that speed up reactions by - Lowering the amount of energy required.

Enzymes are proteins that speed up reactions by reducing the activation energy needed to get them to work. They play a vital role in bodily functions like digestion.

4x and 6y

im not sure though

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
