Questions and Answers 100% Pass
The complete genetic makeup of an organism is called its - ✔✔genome
Imagine that a scientist was able to take pictures of atoms and the position of their
electrons. In one molecule, he found that the shared electron was around one atom 50%
of the time and around the second atom 50% of the time. From this he concluded that
these atoms shared what type of bond? - ✔✔nonpolar covalent
Which of these is not a testable hypothesis? - ✔✔dogs are happier when they are
walked regularly
The chlorine atom has 17 electrons and the sodium atom has 11 electrons. These two
atoms combine to form NaCl. After NaCl is ionized in water, how many electrons are in
the chlorine ion? - ✔✔18
If you could measure the charge coming from various parts of an atom, what charge
would the nucleus have? - ✔✔positive
An atom with 7 electrons in its outer shell will most likely bond with - ✔✔An atom with
1 electron in its outer shell.
A researcher is examining swimming speed in goldfish. She uses a small net to
individually catch 20 goldfish from a large tank of 100 and has them swim along a
narrow raceway one at a time. She measures the swimming speed of each fish to

, determine the average swimming speed of a goldfish. All fish are held at the same
temperature, were fed the same food, swim the same distance and were the same age
and gender. What is wrong with her experiment? - ✔✔She did not use a random sample
A researcher was interested in the impact of exercise on tumor growth in mice. She took
50 mice with tumors and had them walk each day on the treadmill for 6 weeks. All of
the mice were fed the same diet, held under the same environmental conditions and
required to walk the same amount on the treadmill. At the end of the experiment, she
measured the size of their tumors. What is the biggest flaw in her experimental design?
- ✔✔She lacks a control group
The beaches at a nearby lake have been closed because of high E. coli counts. The lake is
surrounded by agricultural areas and summer cottages. We know that different species
of vertebrates have different E. coli strains in their digestive tracts. Which of the
following represents a hypothesis for the source of the high E. coli counts? - ✔✔Runoff
from dairy farms causes high E. coli counts
In science, a theory should - ✔✔-be viewed as knowledge
-be supported by a substantial body of evidence
-provide the ability to make many correct predictions
Macromolecules are polymers composed of monomers. For example polysaccharides
like ___ are made of the repeating monomer ___. - ✔✔cellulose; glucose
You are a medical examiner and are examining the brain tissue of someone who died at
the age of 58. You find a large number of neurofibrillary tangles associated with
hyperphosphorylated tau but no modified â-APP. From this you conclude that this
individual - ✔✔Was likely a boxer and died due to Chronic Traumatic Encephalopathy
A researcher is working with a molecule with the chemical formula C4H8. He notices
that it does not always act the same in chemical reactions or within the cells he is
