WGU BIOLOGY C190 EXAM QUESTIONS
WITH CORRECT ANSWERS
The two new daughter cells will be haploid, but the DNA they contain is still replicated.
The homologous chromosomes have separated and are ready to start the second
division, but they have not yet begun the second round of division.
Which stage of the cell cycle is this cell in? - Correct Answers -Telophase I
Homologous pairs of chromosomes have separated into two cells. Sister chromatids in
each cell have not yet lined up in the middle of the cell.
Which stage of the cell cycle is this? - Correct Answers -Prophase II
Which type of cell division results in sex cells? - Correct Answers –Meiosis
Choose the two substances that are the main components in most eukaryotic cell
membranes. - Correct Answers -Lipids and proteins
Which of these is an output of the light-dependent reaction of photosynthesis? - Correct
Answers -ATP
Which molecule is an input to the Calvin-Benson cycle? - Correct Answers -Carbon
Dioxide
Which stage of cellular respiration releases carbon dioxide as a product? - Correct
Answers -Krebs cycle
Which characteristic describes both meiosis and mitosis? - Correct Answers -Sister
chromatids separate
How is DNA structured during the metaphase stage of mitosis? - Correct Answers -The
centromere at the center keeps DNA lined up at the cell's equator.
What is true regarding the transition from metaphase to anaphase during mitosis? -
Correct Answers -Sister chromatids are aligned along the center of the cell and then
pulled apart into separate chromatids.
Which stage of mitosis is depicted? - Correct Answers -Prophase
, Sister chromatids are being separated and moving towards opposite poles of the cell.
Which stage of mitosis is this? - Correct Answers -Anaphase
Chromosomes are structures that contain hereditary material that will be passed from
one generation to the next.
According to this information, which organic molecule must be present in
chromosomes? - Correct Answers -DNA
A cell has divided its chromosomes into two new nuclei. The cytoskeleton of the cell is
currently pinching the cell in the middle to form two new cells.
In which stage of the cell cycle is this cell? - Correct Answers -Cytokinesis
What is the function of the histones during S phase? - Correct Answers -Organizing and
helping to unwind the DNA so the replication enzymes can access it
What is the function of the flagellum? - Correct Answers -Locomotion and sensing
What is true of a eukaryotic cell? - Correct Answers -It contains mitochondria.
Some cells need to maintain a set concentration of Na + and K + ions. These cells are
able to do this with the help of the Na/K pump, which transports these ions from areas
of low concentration to areas of high concentration (against their concentration
gradient). Na + is pumped out, and K + is pumped in.
Which type of membrane transport is involved in this action? - Correct Answers -Active
transport
Which stage of cellular respiration releases the most energy and, therefore, produces
the most ATP molecules? - Correct Answers -Electron transport chain
In the human body, muscle fibers metabolize sugars to produce energy. Fast-twitch
muscle fibers, like those used during short-term, vigorous exercise, carry out an
anaerobic process that produces less energy per sugar molecule processed.
Which metabolic process do fast-twitch muscle fibers carry out? - Correct Answers -
Fermentation
Fermentation uses sugar in the absence of which molecule? - Correct Answers -O 2
A subatomic particle has a negative charge and is found in a shell of the atom.
What is this particle? - Correct Answers -An electron
