ANSWERS GUARANTEED TO PASS
◉ All organisms are composed of one or more cells; Cells are the
smallest unit of life; Cells come from pre-existing cells via cell
division Answer: List the three principles of the cell theory:
◉ Metabolism, growth, reproduction and cells. Answer: What are the
4 qualifiers of life?
◉ Larger molecules like proteins, carbohydrates, nucleus acids,
lipids and water. Answer: Cells are composed of:
◉ Electron microscope does not rely on the visible light spectrum.
Answer: How do light microscopes and electron microscopes differ?
◉ Different parts arranged in specific patterns Answer: Systems are
composed of:
◉ Transfer of genes through lineage i.e. mother to daughter
(asexually) or through gametes (sexually). Answer: What is Vertical
Gene Transfer?
,◉ Transfer of genes from organism that may not be directly related
i.e. antibiotic resistance transferred between some bacterial species.
Answer: What is Horizontal Gene Transfer?
◉ Fungi, Plantae, and Animalia Answer: What are the 3 kingdoms
within the domain Eukarya?
◉ Atoms connected by bonds Answer: What are molecules?
◉ Covalent and hydrogen bonds Answer: What types of bonds are
present in CFTR protein transporter and hemoglobin?
◉ Hydrogen, Carbon, Nitrogen, Oxygen Phosphorous and Sulfur
Answer: What elements or atoms are particularly important to
biology?
◉ Strong; Shares electrons Answer: Define a covalent bond
◉ Strong; Complete transfer of electrons from one atom to another.
This transfer results in two ions. Ex: NaCl or salt Answer: Define an
ionic bond
, ◉ Weak; Shares hydrogen atom between two other molecules
frequently found in proteins and nucleus acids Answer: Define a
hydrogen bond
◉ Sharing electrons Answer: Define a Van der Waals bond
◉ Excludes or does not interact with water. Ex: lipids are repulsed
from water Answer: Define hydrophobic interactions
◉ They generate the emergent properties that make compounds
different from atoms; the different arrangements help us predict
interactions between atoms. Answer: Electrons are important for
bonds because
◉ Partial charges Answer: When the atoms involved have different
electro negativities and covalent bonds
◉ Different Answer: Polar bonds have ____________ elecronegativities.
◉ Non-polar molecules cannot form hydrogen bonds with water;
therefore, not soluble in water and aggregates to surface in clumps
Answer: What hydrophobic interactions make non-polar molecules
different than charged molecules?
