Biology 101 Test 1 (Full Study Guide) Exam
Questions and Answers
About 25 of the 92 natural elements are known to be essential to life. Which 4 of these 25
make of 96% of living matter? - -carbon, hydrogen, nitrogen, oxygen
-Knowing just the whole number of an element allows inferences about which of the
following? - -the number of protons plus neutrons in the element
-When two atoms have the same level of attraction for electrons, the type of interaction
between these two atoms can be described as - -nonpolar covalent bond
-What is the difference between covalent bonds and ionic bonds? - -Covalent bonds
involve the sharing of electrons between atoms; ionic bonds involve the electrical
attraction between atoms of opposite charge

-A carbon atom is most likely to form which of the following bonds with other atoms? - -
Covalent bonds
-Which two functional groups are always found in amino acids? - -carboxyl and amino
-Which of the following is NOT a correct monomer/polymer pairing defining a
macromolecule? - -Amino acid/DNA
-Which of the following best summarizes the relationship between dehydration reactions
and hydrolysis? - -Dehydration reactions assemble polymers, and hydrolysis reactions
break down polymers
-The smallest unit show below is: - -atom

anaerobic respiration
-ATP is involved in the process of: - -active transport
-Phagocytosis is a type of: - -Endocytosis
-Golgi complex - -protein processing
