Question

___________ are lipids that store energy and are typically composed of multiple building blocks containing three fatty acids attached to a glycerol molecule.
A) Fats
B) Phospholipids
C) Proteins
D) Steroids

Answer 1

B i believe

Answer 2

Lipids form proteins so it couldn't be C right?

Answer 3

That's what I was thinking @nerdgirl6

Answer 4

Name the 7 properties of water
A) Cohesion, Adhesion, Surface Tension, Low Specific Heat, Low Heat of Vaporization, Ice Floats, Universal Solvent
B) Cohesion, Adhesion, Surface Tension, Low Specific Heat, Low Heat of Vaporization, Ice Floats, Universal Solute
C) Cohesion, Adhesion, Surface Tension, High Specific Heat, High Heat of Vaporization, Ice Floats, Universal Solvent
D) Cohesion, Adhesion, Surface Tension, High Specific Heat, High Heat of Vaporization, Ice Floats, Universal Solute

Answer 5

I believe C is correct
It is high heat of vaporization so A and B are out and water is the solvent not the solute so that leaves C

Answer 6

What differs between two isotopes of the same substance.
A) The number of neutrons
B) The number of protons
C) The number of electrons
D) The number of protons and electrons

Answer 7

B for sure

Answer 8

What kind of bonds hold water molecules together (between the hydrogen and oxygen)
A) Covalent
B) Ionic
C) Hydrogen
D) Metallic, Metallic

Answer 9

I believe C they are called hydrogen bonds...but I'm not sure if that is what it means in the context of this question. Hydrogen bonds are covalent, so it may be A

D) hypothesis

Answer 11

That one is B :)

Answer 12

A) The temperature it takes to raise 1g of a substance by 1 degree C
B) The temperature it takes to raise 1g of a substance by 1 degree F point
C) The temperature in Celcius to boil 1g of a substance at boiling
D) The temperature in Fahrenheit to boil 1g of a substance at boiling point

Answer 13

I believe it is C, since Celsius is primarily used in science

A) lipids
B) proteins
C) nucleic acids
D) carbohydrates

Answer 17
