Biology Review Questions With All Correct Answers
Which of the following questions is most relevant to understanding the Calvin
cycle? correct answer -How is ATP used in the formation of 3-carbon
carbohydrates?
What does crossing over, conjugation, and fertilization all have in common?
correct answer -An increase in genetic variation
hypotonic correct answer -cells expand
hypertonic correct answer -cells shrink
The eggs laid by hybrids hatch less often than those hatched by other
populations. What isolating mechanism seems to be important in this hybrid
population? correct answer -Reduced hybrid fertility
A new mutation that arose in one copy of gene x in a somatic cell resulted in a
tumor. Which of the following pieces of evidence best describes how the new
mutation directly caused the tumor? correct answer -Protein x normally
stimulates cell division and the mutation created an overactive version of
protein x.
m phase of cell cycle correct answer -The M phase, or Mitotic phase,
consists of the following stages:
Prophase - The chromosomes condense, centriole pairs separate and move
towards the opposite ends of the cell, and formation of the spindle apparatus
occurs. The nuclear envelope also dissolves so the spindle fibers can enter the
nucleus. Kineotocores and kinetofibers appear at the chromosome's
centromere.
what does macrophage do in terms of a virus? correct answer -It engulfs
the virus and then destroys it.
Which most likely contributes to the specific expression pattern of gene x?
correct answer -The activator is a sequence-specific DNA-binding protein
that is present in some tissues but not in others.
