asu bio exam 3
What factors are examined by the field of demography? - CORRECT
ANSWER-birth and death rates in a population
population size
distribution of ages in a population
What is true of exponential growth? - CORRECT ANSWER-It can be seen in
nature when a population arrives in a new area without natural enemies.
A population's resources must be unlimited for it to occur.
In the graph below, the population represented by the orange (top) line -
CORRECT ANSWER-has the fastest growth rate early, but slows down sooner.
The difference between the two lines on the graph below is - CORRECT
ANSWER-the carrying capacity.
A population would be most likely to have a low growth rate under what
condition? - CORRECT ANSWER-near carrying capacity
A group of interbreeding individuals occupying the same habitat at the same time
is a(n) - CORRECT ANSWER-population
You find a notebook that has lots of equations, tables, and graphs in it. The
tables have columns for the number of female offspring born over a year, the
number of deaths over a year, and the number of individuals in various age
classes. What subject do you think the owner of the notebook is studying? What
type of tables are they most likely using? - CORRECT ANSWER-demography;
life tables
A mark-recapture program marked 10 individuals in the first catch. The second
catch has a total of 8 individuals, 4 of which were recaptures. What is the
estimate of total population size? - CORRECT ANSWER-20

A good sampling method for quantifying the density of birds or bats is the use of -
CORRECT ANSWER-the ability to move through the environment
cephalization
the ability to detect prey
In triploblastic animals, the inner lining of the digestive tract is derived from the -
CORRECT ANSWER-endoderm
Pseudocoelomates - CORRECT ANSWER-have a fluid-filled cavity that is
partially lined with mesoderm
Protostomes and deuterostomes can be classified based on - CORRECT
ANSWER-cleavage pattern.
destiny of the blastopore.
whether the fate of the embryonic cells is fixed early during development.
Indeterminate cleavage is found in - CORRECT ANSWER-vertebrae's
Naturally occurring identical twins are possible only in animals that - CORRECT
ANSWER-have spiral and determinate cleavage and are protostomes.
Genes involved in the patterning of the body axis, that is, in determining
characteristics such as neck length and appendage formation, are called -
CORRECT ANSWER-Hox genes
A major finding of recent molecular studies is that - CORRECT ANSWER-the
presence or absence of a coelom is not important for classification.
