TCC BIO 2401: Anatomy and Physiology (Test 1) Questions
| 2026/2027 | Answers Correct | With Complete Solutions
4 elements that make up 96% of the body Correct Answers
Oxygen - 65%
Carbon - 18.5 %
Hydrogen - 9.5 %
Nitrogen - 3.3 %
7 necessary functions for life Correct Answers 1. Maintaining
boundaries
2. Movement
3. Responsiveness
4. Digestion
5. Metabolism
6.Excretion
7. Reproduction
8. Growth
Anatomy Correct Answers the structure of body parts and their
relationship to one another
anion Correct Answers A negatively charged ion. Gains one or
more electrons. Electrons are donated, not shared.
apoenzyme Correct Answers The protein portion of an enzyme.
Appendicular Correct Answers limbs and appendages
Atomic # Correct Answers # of protons in the nucleus
, Axial Correct Answers head, neck, trunk
Cation Correct Answers positively charged ion. Loses one or
more electrons
coenzyme Correct Answers If the cofactor is an organic
molecule.
cofactor Correct Answers nonprotein component
Compare and contrast the nucleotides of DNA and RNA
Correct Answers DNA nucleotides have deoxyribose sugar,
while RNA nucleotides have ribose sugar; additionally, DNA
contains the base thymine (T) while RNA contains uracil (U) in
place of thymine, with both sharing the other bases adenine (A),
guanine (G), and cytosine (C)
components of nucleotide Correct Answers A nitrogen-
containing base
A pentose sugar
A phosphate group
Contrast the structure of DNA and RNA Correct Answers
DNA has deoxyribose, RNA has ribose. DNA has double strand,
RNA has singular. DNA's nitrogen bases are A,T,G,C, RNA has
all but instead of t it's u. DNA's location in the cell is in the
nucleus only, whereas RNA is in the nucleus AND cytoplasm.
Covalent bonds Correct Answers electron sharing produces
molecules in which the shared electrons occupy a single orbital
common with both atoms.
