College Biology 101 Final Exam Questions
and Correct Answers
Break Down of the word "Biology" - CORRECT ANSWER✅✅✅"Bio" = Life
and
"Logia" = Study Of
The Features of Living Things - CORRECT ANSWER✅✅✅1. Metabolism
2. Regulated Growth
3. Reproduction
Metabolism - CORRECT ANSWER✅✅✅The sum total of chemical reactions taking place
within the body/organism.
Within a Metabolism there is? - CORRECT ANSWER✅✅✅Anabolism & Catabolism
Anabolism - CORRECT ANSWER✅✅✅Building up of synthetic reactions
(Note: Steroids initiate the production of new proteins in the body)
Catabolism - CORRECT ANSWER✅✅✅degredational/break down reactions
Autotroph - CORRECT ANSWER✅✅✅Organisms that make its own food.
*Auto = self
*Troph = feed
Chemoauthrophs - CORRECT ANSWER✅✅✅Creatures that don't rely on sunlight
,They feed on chemicals in the environment
Phtoautotrophs - CORRECT ANSWER✅✅✅-photo = light (feeder)
-Plants that make their own food. I.e. Plants and Algae
Photosynthesis - CORRECT ANSWER✅✅✅process by which plants and some other
organisms use light energy to convert water and carbon dioxide into oxygen and high-energy
carbohydrates such as sugars and starches
Formula for Photosynthesis: CO2 + H2O —(sunlight)-—> C6H12O6 +O2
Hetertrophs - CORRECT ANSWER✅✅✅"Other feeders" or organisms that don't make their
own food. They ingest preformed organic molecules i.e. "eat"
Homeostasis - CORRECT ANSWER✅✅✅A tendency to maintain a balanced or constant
internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a
particular level
-Simpler: What we strive for/our steady state or balance.
-ex. body temp 98.6 F = 37 C (what we maintain) above this we get fever and our enzyme sys.
breakdown. We perspire when its hot. We go into the shade physiologically.
Regulated Growth - CORRECT ANSWER✅✅✅We grow by "genetically programed
growth and there is programed cell death"
Genes - CORRECT ANSWER✅✅✅blue print that provides protein for growth
, Apoptosis - CORRECT ANSWER✅✅✅programmed cell death
-Sometimes cells are designed to fail. Classic Ex = is the embryo ...cells between the fingers are
designed to die off to produce fingers so we don't have webbed hands.
Reproduction - CORRECT ANSWER✅✅✅Can be Asexual (1 parent) or Sexual (2 parents)
Asex - CORRECT ANSWER✅✅✅clones, making copies of yourself - if conditions are
stable this works.
Sex - CORRECT ANSWER✅✅✅Environments change so we get mixing of genes
-variations = different gene combinations through sex
Why may reproduction reduce survival chances ? - CORRECT ANSWER✅✅✅Examples:
1. By exposing self to predators, if you have babies and you have to go out in the wild to feed
them
2. Babies need milk which is a "complete food" that the mother produces. milk has calcium and
if body isn't getting, it takes from mothers bones and affects health.
Goldilocks Hypothesis - CORRECT ANSWER✅✅✅Conditions on earth are just right for
life. We have water, we have a blanket around earth which is the atmosphere. (protects us from
UV rays of sun and regulates temperature)
Hierarchy of Biological Organizations - CORRECT ANSWER✅✅✅1. Molecules
2. Organelles
3. Cells
4. Tissues
5. Organs
