BIO 002 MIDTERM II STUDY GUIDE FALL 2022
I. The most fundamental classification of all living things is based on the presence or absence of a nucleus.
II. What are the typically common shapes found for prokaryotes?
A. Spherical
B. Rodlike
C. Corkscrew
III. Mitochondria are thought to have evolved from aerobic bacteria that took to living inside the anaerobic
ancestors of today's eukaryotic cells.
IV. According to one of the figures in chapter 1 of the textbook, which of these statements is true? Select all
that apply:
Some prokaryotic cells exist as multicellular filaments
Some prokaryotic cells may have internal membranes to perform specialized functions such as
photosynthesis
All prokaryotic cells are single celled
Only plants are able to perform photosynthesis
Some bacterial cells can fix nitrogen from air
A. Some prokaryotic cells exist as multicellular filaments
B. Some prokaryotic cells may have internal membranes to perform specialized functions such as
photosynthesis
C. Some bacterial cells can fix nitrogen from air
V. Many of the mechanisms that cells use for maintenance and reproduction were first studied at the
molecular level in bacteria. Which bacterial species had a central role in advancing the field of molecular
biology?
A. E. coli
VI. Changes in DNA sequence from one generation to the next may result in ofspring that are altered in
fitness compared with their parents. the process of change and selection over the course of many
generations is the basis of evolution
VII. What conforms to the central dogma of biology?
A. rna ⇒ proteins
B. dna ⇒ rna
VIII. Mitochondria contain their own genome, are able to duplicate, and actually divide on a diferent timeline
from the rest of the cell. Nevertheless, mitochondria can't function for long when isolated from the cell
because they are endosymbionts.
IX. The diference between cell cytoplasm and the cytosol is the cytoplasm includes all material between the
plasma membrane.

X. The element with atomic number 9 is not shown.
However, from this pattern, what kind of molecular force would it most likely participate in?
A. Ionic
XI. The mass of a proton is approximately equal to the mass of a neutron.
XII. True or False: the innermost is approximately equal to the mass of a neutron.
XIII. If the isotope 32-S has 16 protons and 16 electrons, how many protons, neutrons, and electrons will the
isotope 39-S have?
A. 16 protons
B. 23 neutrons
C. 16 electrons
XIV. What is it called when an atom has more electrons than protons?
A. Anion
XV. All living cells obey the same chemical and physical laws as nonliving things. like all other forms of matter,
they are made of atoms which are the smallest unit of a chemical element that retain the distinctive
chemical properties of that element.
XVI. Cells are made up of a limited number of elements, four of which make up about 96% of a cell's mass.
A. H
B. C
C. O
D. N
XVII. Avogadro's number references the number of 'things' in a mole of that substance.
XVIII. The molecular weight of an atom is given by the equation protons + neutrons.
XIX. Which of the following laws of physics/chemistry may living things not violate?
A. Bonding
B. Chemical reactions
C. Chemical structures
D. Motion
XX. What is an example of a polysaccharide?
A. Glycogen
B. Chitin
C. Starch
D. Cellulose
