A&P 101 CHAPTER 1-3 STUDY TEST
QUESTIONS WITH COMPLETE
SOLUTIONS
What makes RNA a unique nucleic acid? - Answer- RNA contains a nitrogenous base
known as uracil.
Transcribe mRNA from this strand of DNA.T A C G G T A G T - Answer- A U G C C A U
CA
When you go outside on a hot summer day, your body temperature heats up above the
normal range. Receptors in your brain detect the change in body temperature. The brain
activates nerve cells that send messages to sweat glands, causing the body
temperature to fall as the sweat evaporates from the skin. What part of this feedback
loop is the stimulus? - Answer- increased body temperature
What predicts the element to which an atom belongs? - Answer- otal number of protons
What forms the basis for the body's steroids? - Answer- cholesterol
The primary source of chemical energy in the body comes from a nucleotide known as:
- Answer- ATP
The formation of a cation and an anion is indicative of a(n): - Answer- ionic bond
The monomer of the carbohydrates is the: - Answer- fatty acid
A white blood cell engulfs a bacterium through a process called: - Answer- endocytosis
Which of the following is the correct sequence, from simplest to most complex, in the
levels of structural organization of the human body? A) cellular level, tissue level,
chemical level, organ level, organ system level, organismal level B) cellular level,
chemical level, tissue level, organ level, organ system level, organismal level C)
chemical level, cellular level, tissue level, organ level, organ system level, organismal
level D) chemical level, tissue level, cellular level, organ system level, organ level,
organismal level - Answer- C) chemical level, cellular level, tissue level, organ level,
organ system level, organismal level
Which of the following is the most complex structural level of organization? - Answer-
