BIO 1033 FINAL EXAM BROC EXPECTED QUESTIONS
WITH VERIFIED ANSWERS
Question 1.
characteristics of life
ANSWER
cells are simplest units of life, respond to stimuli(homeostasis), reproduction, evolution(ability to
change over time), transform & use energy(metabolism)
Question 2.
Steps of the Scientific Method & what is "control" in a experiment ?
ANSWER
observation hypothesis prediction experiment analyze data/ collect data conclusion the control of the
experiment is used for comparison, it does not receive any treatment.
Question 3.
define:
population, community, ecosystem, & biosphere
ANSWER
population: all organisms of the same species that live in a particular geographic area. community: a
group of ppl living in the same place. ecosystem: A system that includes all living organisms (biotic
factors) in an area as well as its physical environment (abiotic factors) functioning together as a unit.
is made up of plants, animals, microorganisms, soil, rocks, minerals biosphere: is defined as the area
of the planet where organisms live, including the ground and the air. An example of the biosphere is
where live occurs on, above and below the surface of Earth.
Question 4.
Know the characteristics of the three Domains of life: Bacteria, Archaea and Eukarya. difference
ote & eukaryote?
ANSWER
bacteria: unicellular prokaryote archaea : unicellular prokaryote eukarya : unicellular and
multicellular eukaryotes
• Complex cells with a nucleus
• Four kingdoms:
difference between pro and eukaryote : bacteria(pro) inhabits in many diverse environments, archaea
live in extreme live hot springs, eukaryote organisms having cells with internal compartments that
serve various functions.

,Question 5.
Who posses a membrane bound organelle (nucleus)?
ANSWER
eukaryotic cell
Question 6.
what is a nomenclature ? which one is genus name? which one is species name?
ANSWER
• Binomial nomenclature
Each species has a unique scientific name Genus name capitalized Species descriptor is not
capitalized Both names are italicized Amphiprion ocellaris = Ocellaris clownfish genus name :
Amphiprion species name: ocellaris
Question 7.
know structure of an atom and the atomic particles
ANSWER
• Protons
positivecharge(+) found in nucleus
• Neutrons neutral
found in nucleus
• Electrons
negativecharge(-) found in orbitals
Question 8.
define hydrogen bond, ionic bond, covalent bond
ANSWER
• Covalent Bond
Electrons are shared to fill valence shells Can be polar covalent or nonpolar covalent • Hydrogen
Bond Hydrogen atom from one polar molecule is attracted to an electronegative atom from another
molecule Electrons are transferred, forming ions that are attracted to each other
Question 9.
What is the bond between hydrogen and oxygen in water and between two water molecules
that keep then attached together?
ANSWER
hydrogen bond
2
, Question 10.
a water molecule is?
ANSWER
polar
Question 11.
What are the most common elements of living things? What CHON stands for?
ANSWER
1. Hydrogen, 2. oxygen, 3. carbon, & 4. nitrogen
Question 12.
Know the 4 characteristics of water
ANSWER
cohesive, polar, solvent, high heat of vaporization.
Question 13.
What is pH? Which one is most acidic? Stomach fluid, small intestine fluid, semen, blood? many
electrons in its outer shell? It can form how many bonds?
ANSWER
pH is measuring the hydrogen ions in a acid or base. stomach fluid
Question 14.
what are the monomers that go with the polymers:
carbohydrate,nucleic acid, protein, lipids
ANSWER
monosaccharides,nucleotide,amino acid, fatty acid
3
