Test

Question 1

Water

Answer 1

A molecule composed of two hydrogen atoms and one oxygen atom

Question 2

Polar Molecules

Answer 2

Polar molecules are molecules that have a dipole or an uneven distribution of charge across their geometry resulting in one side being positive and the other side negative.

Question 3

Cohesion

Answer 3

The tendency of molecules of the same type to stick together, primarily due to attractive forces between them

Question 4

Adhesion

Answer 4

The tendency of dissimilar substances or surfaces to cling to one another

Question 5

Hydrogen bonds

Answer 5

A hydrogen bond in biology is a weak electrostatic attraction between a partially positive hydrogen atom, covalently bonded to a highly electronegative atom like oxygen or nitrogen, and a lone pair of electrons on another electronegative atom in a nearby molecule

Question 6

Carbon

Answer 6

In biology, carbon is a chemical element that serves as the fundamental building block of all life on Earth

Question 7

Macromolecule

Answer 7

In biology, a “macromolecule” refers to a very large molecule, typically composed of smaller repeating units called monomers

Question 8

Monomer

Answer 8

A single, small molecule that acts as a building block to form larger, more complex molecules called polymers by linking together with other monomers through chemical bonds

Question 9

Polymer

Answer 9

In biology, a polymer is a large molecule composed of many repeating smaller units called monomers

Question 10

Carbohydrate

Answer 10

A carbohydrate is an organic compound such as sugar or starch, and is used to store energy.

Question 11

Monosaccharide

Answer 11

A monosaccharide, in biology, is a simple sugar molecule, considered the basic unit of carbohydrates

Question 12

Disaccharide

Answer 12

A type of sugar molecule formed when two simpler sugar units are joined together by a glycosidic

Question 13

Polysaccharide

Answer 13

A complex carbohydrate molecule made up of long chains of many simple sugar units

Question 14

Lipids

Answer 14

Any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.

Question 15

Nucleic Acid

Answer 15

Nucleic acids are large biomolecules that play essential roles in all cells and viruses.

Question 16

DNA

Answer 16

DNA stands for “deoxyribonucleic acid,” a molecule found inside cells that contains the genetic information necessary for an organism to develop and function, essentially acting as the instruction manual for life

Question 17

RNA

Answer 17

Ribonucleic is RNA and it is like the copy of DNA that is able to leave the cells

Question 18

Protein

Answer 18

A specific DNA sequence located upstream of a gene where RNA polymerase binds to initiate the process of transcription

Question 19

Amino Acids

Answer 19

In biology, an amino acid is a small organic molecule that serves as the basic building block of proteins

Question 20

Enzyme

Answer 20

In biology, an enzyme is a protein molecule that acts as a biological catalyst, significantly speeding up the rate of a specific chemical reaction within a cell without being consumed in the process

Question 21

Catalyst

Answer 21

A substance, usually a protein called an enzyme, that speeds up a chemical reaction within a living organism without being consumed in the process

Question 22

Substrate

Answer 22

The surface or substance on which an organism lives, or the substance that an enzyme acts upon to produce a chemical reaction
