USAFA Bio 215 Block 1 UPDATED Exam
Questions and CORRECT Answers
Select the appropriate Principle of Biology: Your DNA codes for the creation of insulin (protein)
in pancreatic cells used to help regulate blood sugar in the body. You inherited this code from
your parents and will pass the code on to your kids. - CORRECT ANSWER - Information
Flow, Exchange, and Storage
Select the appropriate Principle of Biology: The branched structure in your lungs provides high
surface area over which a very high volume of air may pass. - CORRECT ANSWER -
Structure and Function
How do hypotheses differ from theories? - CORRECT ANSWER - Theories are more
comprehensive than hypotheses.
Select the appropriate Principle of Biology: Fungi are decomposers that breakdown waste and
the remains of dead organisms, changing complex molecules into simple nutrients making
nutrients available for plants to take up from the soil. - CORRECT ANSWER - pathways
& transformation of energy and matter
What best describes a theory? - CORRECT ANSWER - A comprehensive explanation of
natural phenomena supported by abundant evidence
Select the appropriate Principle of Biology: Changing weather patterns and water levels has
increased the range of several species of disease-causing mosquitoes bringing illness to parts of
the world not previously affected by the disease. - CORRECT ANSWER - Systems
A hypothesis is a(n)? - CORRECT ANSWER - tentative answer to a question
Select the appropriate Principle of Biology: All mammals have hair and produce milk through
mammary glands. We would expect such similar characteristics in all mammals descended from
a common ancestor (first mammal). - CORRECT ANSWER - Evolution
, A fat molecule is composed of two types of smaller molecules: _______ and fatty acids. -
CORRECT ANSWER - glycerol
_____ are the monomers from which large proteins are constructed. - CORRECT
ANSWER - Amino acids
Science is ________. - CORRECT ANSWER - the inquiry-based effort to describe and
explain nature
___________ are a major component of cell membranes. They form a bilayer with their
hydrophobic tails mingling together and their hydrophilic heads facing the watery environment
on both sides of the membrane. - CORRECT ANSWER - phospholipids
Starch is a ___________ and its function is ___________. - CORRECT ANSWER -
polymer; energy storage in plants
Which of these would be a valid scientific hypothesis? - CORRECT ANSWER - Humans
and bacteria share a common genetic code.
Each different protein is unique due to its _________. - CORRECT ANSWER - sequence
of amino acids
The hydrocarbon chains of ___________ are not kinked, and thus pack closely together, making
animal fats solid at room temperature. - CORRECT ANSWER - saturated fatty acid
The plasma membrane forms a pocket that pinches inward, forming a vesicle that contains
material from outside the cell. This describes the process of - CORRECT ANSWER -
endocytosis.
