Chemistry of Life Part 1

Question 1

What are hydrogen bonds?

Answer 1

Attraction between the negative end of one molecule and the positive end of another molecule. They’re incredibly weak.

Question 2

What are the types of covalent bonds?

Answer 2

Single, Double, Triple, Polar, Nonpolar, and Coordinate.

Question 3

What are covalent bonds?

Answer 3

Atoms that share one or more pairs of electrons so that the outer shells are filled. It takes a lot of energy for them to break.

Question 4

What are ionic bonds?

Answer 4

Bonds formed by the transfer of valence electrons to get stability.

Question 5

What type of sugar is DNA made from?
RNA?

Answer 5

Deoxyribose and ribose.

Question 6

What does DNA and RNA stand for?

Answer 6

Deoxyribonucleic acid and Ribonucleic acid

Question 7

The head of a phospholipid is ________ and the tail is ________

Answer 7

Hydrophilic, hydrophobic.

Question 8

What are van der Waal forces?

Answer 8

Attraction between nonpolar molecules that are close together. They’re typically weak and brief.
