BIO 316 Exam 1 Questions and Answers

| Verified | Updated 2024


Physiology - ✔✔The branch of biology that deals with the functions of living

organisms and their parts

natural selection - ✔✔Organismal function has been shaped by _________

in different environments.

Darwin's 4 postulates of natural selection - ✔✔1. Phenotypes vary within

populations

2. Some of this variation is passed on to offspring

3. In every generation, more offspring are produced than can survive

4. Some individuals survive and reproduce more effectively that others, and

this success is associated with their phenotypes

predict - ✔✔Evolutionary reasoning allows us to ________ physiology

based on knowledge about local environments, not just

catalogue it across organisms and environments.

Intergrative - ✔✔Physiology affects and/or responds to all levels of

biological organization; Physiology is an inherently ________ discipline.

,Mechanisms and Origins - ✔✔What are the 2 broad types of questions in

animal physiology about?

What is the mechanism by which a function is accomplished? - ✔✔State

the question on mechanisms.

proximate causation - ✔✔What is the question about mechanisms about?

How did that mechanism come to be? - ✔✔State the question on origins.

ultimate causation - ✔✔What is the question about origins about?

Mechanism - ✔✔Interactions between the components of living animals

that enable these animals to perform and function as they do.

Mechanism - ✔✔The field of physiology is most clearly differentiated from

other fields (e.g. ecology, animal behavior) by this focus on _______.

Evolution - ✔✔Questions about the origin of a physiological function are

fundamentally about the ________ of that function and its broader

ecological and adaptive significance

Inference - ✔✔Answers to questions about origin are usually understood

with less certainty than questions about mechanism, because they often

rely on indirect forms of _______.

Adaptations - ✔✔Physiological mechanisms are almost always

_________—traits that have arisen as a result of natural selection.

, Animal Physiology - ✔✔________ is an inherently integrative field of study

that asks questions about the origin of, and mechanisms underlying, animal

function.

Evolutionary - ✔✔The field of animal physiology is based heavily in

_______ biology, and specifically, the ways in which physiological features

have arisen via natural selection.

Predict - ✔✔Evolutionary theory allows us to ______ what physiological

functions a given species might have, and it gives us a basis for making

hypotheses.

Continuous; dynamic - ✔✔The atoms of animal bodies undergo ________

and _______ exchange with the atoms of their environments

organization - ✔✔In animals, it is the general ________ of these atoms that

persists through time, rather than the individual atoms themselves

Energy - ✔✔To maintain organization of atoms, animals require the input of

______.

Homeostasis - ✔✔Because animals dynamically interact with their

environment, they must maintain _______.

Homeostasis - ✔✔The maintenance of a stable (or nearly stable) internal

environment
