BIO 182 STUDY GUIDE WITH
COMPLETE SOLUTIONS
In biology, what is meant by form and function? - Correct Answers -Form directly
influences the function. If structure found in an animal is adaptive-it helps the individual
produce offspring-then the structure's size,shape,or composition often correlates closely
with its function
What is meant by the statement: ...adaptations are trade-offs? Describe a few
examples. - Correct Answers -Expenditures of time and energy.
How is surface area related to volume? How do they both change with increasing size?
- Correct Answers -Volume increases faster than surface area
How is adaptation different from acclimation? - Correct Answers -Acclimatization-
phenotypic change that occurs in an individual in response to a short-term change in
environmental conditions
Physiology- the study of how the physical structures in an organism function
Homeostasis - Correct Answers -maintenance of relatively constant chemical and
physical conditions in an animal's cells, tissues, and organs.
Temperature Regulation - Correct Answers -Biggest variation among animal species:
amount of heat generated by the animal's own tissues and the degree to which body
temperature varies over time....
What is Homeostasis? - Correct Answers -The maintenance of relatively constant
chemical and physical conditions in an animal's cells, tissues, and organs.
What kinds of organisms use homeostasis? What does an organism need to regulate
various parameters? - Correct Answers -An organism uses a set point, integrator, and
an effector.
cover the body and line organs- - Correct Answers -epithelial tissues
connective tissues - Correct Answers -support and reinforce other tissues
muscle tissues - Correct Answers -contract, made up of fibers
, nervous tissues - Correct Answers -process information and transmit electrical signals-
Digestive - Correct Answers --digestion and absorption; mouth, esophagus, and
stomach.
Endocrine - Correct Answers -secretes different hormones that regulate metabolism,
growth development, tissue function, sexual function, reproduction, sleep and mood----
Organs-pituitary gland, thyroid gland, parathyroid gland, adrenal glands, pancrea
circulatory - Correct Answers -Transports materials, oxygen absorbed into the
lungs.....Organs- heart and blood vessels (arteries, veins, and capillaries)
nervous - Correct Answers -percieve and comprehend; sensory neurons;..organs- Brain
and Spinal Cord
respiratory - Correct Answers --To supply blood with oxygen in order for the blood to
delivery Oxygen to all parts of the body. Through breathing. Organs- Nose, mouth,
pharynx, larynx, trachea, bronchi
excretory - Correct Answers -elimination of wastes produced through homeostasis-
Organs- sweat glands, liver, lungs, and kidney system
skin - Correct Answers -Protection, regulation, and sensation
Negative Feedback- - Correct Answers -Regulatory systems depend on it- Occurs when
regulatory system makes a change in the opposite direction to a change in internal
conditions (equivalent to a heater turning on and raising temperature when a room has
cooled off)
Endotherm- - Correct Answers -- Produces own heat maintain enzymes at optimal
temperatures at all times, so mammals and birds are able to remain active in winter and
at night. Due to their high metabolic rates and insulation endotherms are also able to
sustain very high levels of aerobic activities.
Ectotherm - Correct Answers -relies on heat gained from the environment
How do ectotherms and endotherms regulate body temperature? Are they similar or
different - Correct Answers -Homeostasis- endotherms
Environments- Ectotherms- lizards basking
Homeotherms - Correct Answers -keep their body temperature constant
Heterotherms - Correct Answers -experience changes in body temperature
Poikilotherm - Correct Answers -can't regulate body temperature except by behavioral
means
