Learning Objectives WGU C190 questions with verified
answers
Analyze the inputs to and outputs of the stages of photosynthesis Ans✓✓✓-
Inputs: Light, water, carbon dioxide (CO2)
Outputs: Oxygen, sugar (converted to starch)
Analyze the process of natural selection and its relationship to evolution at the
population level Ans✓✓✓-Nature selects those individuals who are best fit for
the environment.
If you have variation, differential reproduction, and heredity, you will have
evolution by natural selection as an outcome.
Evolution is the scientific theory that explains how and why life changes over
time.
Analyze the results of monohybrid crosses Ans✓✓✓-There is a phenotype (visible
traits) and genotype (genetic traits). They are represented by an uppercase letter
(B) and a lowercase letter (b). They are crossed to determine the offspring.

,Apply the process of scientific inquiry to questions about the natural world
Ans✓✓✓-The term natural in this context means all that can be observed with
our senses or with instruments that extend our senses.
Best approach to understanding the natural world and predicting natural
phenomena.
Classify items as biotic (living) or abiotic (nonliving) Ans✓✓✓-Biotic: Living or
having lived
-Bacteria
-Cotton
-Yogurt
Abiotic: Nonliving and never having been alivebiome
-Water
-Glucose
-Carbon Dioxide
-Cold Virus
Compare and contrast the purposes of mitosis and meiosis Ans✓✓✓-Mitosis:
increase the number of cells in an organism during development, replace
damaged cells during wound healing, and produce replacement cells as other cells
undergo naturally pre-programmed death. Parent and daughter cells are
identical.
Meiosis: produce new gametes (sperm and egg). Must reduce the chromosome
number in the daughter cells to half that in the parent cell.
, Compare and contrast the structure and function of animal and plant cells
Ans✓✓✓-**Both animal and plant cells are eukaryotic.**
Plants: chloroplasts, and rigid cell wall. Chloroplast (unique organelles) are able to
harvest solar energy to make sugar from carbon dioxide (known as
photosynthesis).
Animals: consist of everything except for chloroplasts, and a cell wall.
Compare and contrast the structure and function of prokaryotic and eukaryotic
cells Ans✓✓✓-Prokaryotic: Cells w/out a nucleus. The DNA in the cell is the the
cytoplasm rather than enclosed w/in a nuclear membrane. Found in single-celled
organisms such as bacteria.
Eukaryotic: Cells that contain a nucleus. Usually larger than prokaryotes, are
found mainly in multi-cellular organisms such as animals, plants, and protists
(amoeba, algae, fungi).
Compare and contrast the structure and function of the nucleic acids RNA and
DNA Ans✓✓✓-RNA: single stranded, contains ribose, nitrogenous base (A, T, U,
G, & C), transmits proteins for genetic use in DNA.
DNA: double stranded, five-carbon sugar deoxyribose, (A, T, G, C), gives humans
their genetic code/makeup developing looks and personalities.
