glycolysis
Krebs cycle
acetyl CoA formation - ANSWER: glycolysis
Which of the following could be a nucleotide of DNA?
deoxyribose + phosphate group + thymine
deoxyribose + phosphate group + uracil
ribose + phosphate group + thymine
ribose + phosphate group + uracil - ANSWER: deoxyribose + phosphate group +
thymine
Which statement best describes how Watson and Crick's model used other
scientists' work to create a model of DNA?
They used Chargaff's rule to determine that it contains ribose sugar.
They used Franklin's photo to determine that DNA was a double helix.
They used Levene's work to determine the number of base pairs in each strand.
They used Nirenberg and Matthei's studies to determine that DNA is made of
nucleotides. - ANSWER: They used Franklin's photo to determine that DNA was a
double helix.
Drinking too much water during exercise can cause a condition in which the
concentration of sodium in the blood is lower than normal.What immediate
response would the blood cells have in this condition?
Cells swell as water moves into them.
Cells swell as water moves out of them.
Cells shrivel as water moves out of them.
Cells shrivel as water moves into them. - ANSWER: Cells shrivel as water moves out
of them. ??
The sketch shows a rynchosaur, an extinct animal that is known only from fossils.
There has been much debate about the classification of these creatures. Some
scientists suggest that they belong with primitive amphibians, and some think they
are related to snakes and lizards. The data equally support both cases.Which
statement best explains how to draw a cladogram that includes the rynchosaur?
Draw the cladogram for amphibians.
Draw the cladogram for reptiles.
, Draw two cladograms, both showing the traits, and leave it as a hypothesis.
Draw two cladograms, both showing the traits, and have scientists vote. - ANSWER:
Draw two cladograms, both showing the traits, and leave it as a hypothesis.
Which of the following examples can cause gene flow between populations?
an increase in predators to a population of zebra
a volcanic eruption that kills half of a population of mice
bird droppings that contain seeds from a different location
a person that sprays a toxin on a group of mosquitoes - ANSWER: bird droppings that
contain seeds from a different location
Which compound is produced during carbon fixation?
PGA
G3P
RuBP
C6H12O6 - ANSWER: G3P
Fiona wants to use the scientific method to answer the question "Do oxygen levels in
the air affect rates of photosynthesis?" She reads about photosynthesis in her
biology book and is ready to carry out the next step. What should she do next?
perform an experiment
design a procedure
make observations
form a hypothesis - ANSWER: form a hypothesis ??
Which best describes the relationship between DNA, genes, and chromosomes?
DNA are segments of genes that form tight coils called chromosomes.
Genes are segments of DNA that form tight coils called chromosomes.
Chromosomes are segments of DNA that form tight coils called genes.
Genes are segments of chromosomes that form tight coils called DNA. - ANSWER:
Genes are segments of DNA that form tight coils called chromosomes.
Mitosis is important because it allows
new cells to replace old damaged cells.
new cells to repair old damaged cells.
old cells to self-repair when they become damaged.
existing cells to take over the function of damaged cells. - ANSWER: new cells to
replace old damaged cells.
What observation led researchers to propose that chloroplasts evolved from
cyanobacteria?
Both produce proteins.
Both contain mitochondria.
Both provide structure to cells.
Both perform photosynthesis. - ANSWER: Both produce proteins.
