BSC 101 EXAM 1 2026 BIOLOGY TEST
PAPER QUESTIONS ANSWERS
GRADED A+
◉ What is a theory?
Answer: Theories are broad explanations. They are supported by lines o
evidence, with no contradictory evidence. Therefore the evolutionary
theory isn't just a "theory"
◉ Why don't community analysis and feedback insure the accuracy of
scientific information?
Answer: You get peer revisions and discuss with colleagues. During
these discussions, you can come up with new ideas and build theories
◉ What are (6) examples that all living things must do?
Answer: 1. have organized structures made of at least one cell
2. respond to stimuli
3.reproduce, even through adaptions by natural selection
4. Grow and develop
5. Maintain Homeostasis
6. Process energy
◉ What is a Prokaryotic cell?
Answer: Has a cell membrane but no nucleus, and no mitochondria
, ◉ What is a Eukaryotic cell?
Answer: Has a cell membrane, nucleus, and mitochondria. Eukaryotic
cells are also larger than Prokaryotic
◉ What are examples of Prokaryotes?
Answer: Bacteria or Archaea
◉ What are examples of Eukaryotes?
Answer: Animals and Plants
◉ What is a mutation?
Answer: Mutation, or microevolution, is a change in DNA sequence
caused by errors in DNA replication or mutagens, which can be
environmental factors like UV radiation. It must be a sperm or an egg to
be passed on. Some consequences could be there is no change in
phenotype, beneficial, or increase fitness or negative, decrease fitness
◉ What occurs during natural selection?
Answer: There is first genetic variation of the population. Then
differential reproduction, then hereditary difference, then change across
generations in gene pools, phenotypes, and population's fitness.
(Biological fitness is the degree to which an individual can reproduce
and have its genes represented in the next generations)
◉ What are some common misconceptions of evolution?
Answer: 1. That it's just a theory
