BIO 1406 EXAM 1 STUDY Questions with
Detailed Verified Answers
What are the 3 domains? Ans: Domain Bacteria, Archaea, and Eukarya
What domain has prokaryotic members? Ans: Domain Archaea and
Bacteria
What domain has eukaryotic members? Ans: Domain Eukarya
Differentiate prokaryotes from eukaryotes. Ans: Prokaryotes has no
nucleus and is not bounded by nuclear membrane but DNA is surrounded
by the nucleoid. Eukaryotes has a nucleus and DNA is enclosed by
nucleus membrane.
What are the unicellular and prokaryotic organisms? Ans: Archaea and
Bacteria
What are the unicellular and eukaryotic organisms? Ans: Fungi (yeast)
and Protists
What are the multicellular and eukaryotic organisms? Ans: Animals,
Plants, and Fungi (mold)
What are the common themes that reveal the diverse forms of life? Ans:
-Levels of Biological Organization
-Transfer and Transformation of Energy and Matter
-Expression and Transmission of Genetic Information

-Evolution accounts for the Unity and Diversity of Life
Enumerate the levels of organization of living things from smallest to
largest groups at the cellular level. (Give Examples!) Ans: Atoms
(Oxygen, Hydrogen, etc.) -> Molecule (H2O, C6H12O6, etc.) ->
Macromolecule (Proteins: Insulin, Lipids: Fats, Carbohydrates: Glycogen,
and Nucleic Acids: DNA) -> Organelle (Nucleus, Mitochondria, Ribosomes,
Endoplasmic Reticulum, Golgi Apparatus, Lysosomes, and Vacuoles) ->
Cell (Bacteria, Amoebas, Plant & Animal cells, Nerve cells and Red Blood
cells)
Enumerate the levels of organization of living things from smallest to
largest groups at the organismal level. (Give Examples!) Ans: Tissue
(Connective tissue: Bones, Cartilage, and Fat, Muscle tissue: Skeletal,
Smooth, and Cardiac, Nervous Tissue: Found in the Brain, Spinal Cord,
and Nerves) -> Organ (Brain, etc.) -> Organ System (Nervous System,
etc.) -> Organism (Human, Tree, etc.)
Enumerate the levels of organization of living things from smallest to
largest groups at the population level. (Give Examples!) Ans:
Population (Lions living in one specific area, Salmon in a specific river,
etc.) -> Species (Domestic Dog or Cat, etc.) -> Community (Forest,
Pond, etc.) -> Ecosystem (Grasslands, Desert, etc.) ->Biosphere (All
rainforests on Earth, etc.)
What is the basic structural and functional unit of life? Ans: Cell
Give and explain examples how structure correlates to its functions.
Ans: Hummingbird: Long, Narrow beak allows for an easier consumption
of the nectar from a flower. Flexible shoulder joints allow the wings to
rotate 180 degrees, enabling them to fly backwards and stationary
hovering.
Flower: Trumpet-like cone and bright color attracts pollinator and birds to
consume.
What is the major source of energy on earth? Ans: Sun
