BIO 156 Exam 4 Questions and
Answers 2026
Biology -Correct Answer ✔-The study of life
lysogenic cycle -Correct Answer ✔-Many copies of the phage are produced within the
bacteria cell, the bacteria lyses and breaks open
Viruses are living or non-living? -Correct Answer ✔-Non-living because they cannot
produce on their own.
host specific -Correct Answer ✔-attacks plants and people
Cell Specific -Correct Answer ✔-attacks certain cells ( white blood cells)
Prophgae -Correct Answer ✔-Viruses that attack bacteria, DNA is inserted into bacterial
chromosome
Retrovirus -Correct Answer ✔-An RNA virus that reproduces by means of a DNA
molecule. It reverse-transcribes its RNA into DNA, inserts the DNA into a cellular
chromosome, and then transcribes more copies of the RNA from the viral DNA. HIV and
a number of cancer-causing viruses are retroviruses.
Viroids -Correct Answer ✔-small circular RNA molecules that infect plants
Prions -Correct Answer ✔-misfolded proteins that somehow convert normal protiens to
the prion version, leading to disease
3 tyoes of prokaryotic forms -Correct Answer ✔-Spherical, rod shaped, and spiral or
curved shaped
binary fission -Correct Answer ✔-Can reproduce by dividing in half
, Edospores -Correct Answer ✔-thick coated protective cells
skeletal muscle -Correct Answer ✔-Attached to the bone (voluntary)
smooth muscle -Correct Answer ✔-Involuntary muscle found inside many internal
organs of the body
cardiac muscle -Correct Answer ✔-Involuntary muscle tissue found only in the heart.
connective tissue -Correct Answer ✔-loose connective tissue binds epithelial to
underlying tissues & holds organs in place
cartilge -Correct Answer ✔-strong & flexible support material
adipose tissue -Correct Answer ✔-store fat insulation and fuel
blood -Correct Answer ✔-composed of blood cells and cell fragments in blood plasma
Bone -Correct Answer ✔-mineralized and forms the skeleton
Biotechnology -Correct Answer ✔-The manipulation of living organisms or their
components to produce useful products like yeast for bread
Recombinant DNA -Correct Answer ✔-when scientists combine pieces of DNA from two
different sources to form a single DNA molecule
genetic engineering -Correct Answer ✔-direct minipualtion of genes for practical uses
Homeostasis -Correct Answer ✔-A steady state or internal balance regardless of
external environment
reverse transcriptase -Correct Answer ✔-An enzyme encoded by some certain viruses
(retroviruses) that uses RNA as a template for DNA synthesis.
