Nucleus
Endoplasmic Reticulum
Lysosomes
Chloroplasts
Correct Answer
Nucleus - Contains genomic content of the cell
Endoplasmic Reticulum - Series of membrane-enclosed sacs and interconnected tubes
Lysosomes - Contain hydrolytic enzymes capable of degrading unwanted cellular debris
Chloroplasts - Site of photosynthesis

,Question 3
What is the smallest biological unit of life?
Correct Answer
A cell
Question 4
What are the four main types of macromolecules?
Correct Answer
proteins, nucleic acids, lipids, carbohydrates

Page 2 of 33
,Question 6
Briefly explain how a Scanning Electron Microscope (SEM) forms an
image of subcellular organelles, substrates, and viral particles.
Correct Answer
An image is formed from the interactions of electrons
as they reflect off (not through) the surface of the specimen.
Samples are coated in either gold or palladium to enhance
electron reflections. The reflection is seen in 3-D rendering.
Question 7
How many amino acids are essential?
Correct Answer
20
Question 8
Match each of the following diseases to the correct bacterial family.
Scalded Skin Syndrome
Bubonic PLague
Opthalmia Neonatorium
Legionnaires
Correct Answer
Scalded Skin Syndrome - Staph Aureus
Bubonic Plague - Yersina Pestis
Opthalmia Neonatorium - Staphylococcus
Legionnaires - Legionella

Eukaryote.
E.coli
Archaeons
Yeast
Amoeba
Correct Answer
E.coli - Prokaryote
Archaeons - Prokaryote
Yeast - Eukaryote
Amoeba - Eukaryote
Question 10
Match each of the following terms with the correct description.
Phototroph
Lithotroph
Autotroph
Chemotroph
Correct Answer
Phototroph - Utilize photons of light to generate ATP from ADP
Lithotroph - Remove electrons from inorganic molecules
