Which of the following observations most strongly supports the hypothesis
that ants and Acacia trees have experienced one-on-one coevolution? ------
---CORRECT ANSWER-----------------The removal of either trees or ants
from the environment causes the extinction of the remaining species.
T/F: Coevolution has important consequences for medicine because
pathogens coevolve with their hosts. ---------CORRECT ANSWER-------------
----true
How can several species of dung beetles coexist? ---------CORRECT
ANSWER-----------------There has to be something about their niches that
differ; if they both eat dung, it can't be what they eat, but there has to be
something else that keeps them from out-competing one another; there has
to be some other resource that's limiting the one species from getting all
the dung.
True or False? If species of beetles have the same niche, eventually all but
one species will become extinct. ---------CORRECT ANSWER-----------------
true
True or False? If species compete for many generations, natural selection
would cause their niches to diverge. ---------CORRECT ANSWER-------------
----true
,T/F: While spreading through the human population, the viral population
experiences one-on-one coevolution with the population of humans. ---------
CORRECT ANSWER-----------------true,Coevolution the hypothesis that
when the virus and the host reciprocally affect each other's evolution
T/F:When humans and viruses interact as host and pathogen, respectively,
an evolutionary change in one population will result in selective pressure on
the other population. ---------CORRECT ANSWER-----------------true
T/F: Viruses can become less harmful to humans through natural selection
in the human population or natural selection in the viral population. ---------
CORRECT ANSWER-----------------true
T/F: If the immune system of humans evolves to reduce the reproduction of
viruses, the viral population would likely experience the natural selection of
viruses that are less harmful to humans. ---------CORRECT ANSWER--------
---------false
T/F: The deadliest viruses for humans are likely to be ones that have spent
little time infecting the human population. ---------CORRECT ANSWER-------
----------true
Is a linear sequence of organisms through which matter and energy pass --
-------CORRECT ANSWER-----------------food chain
The different types of organisms are organized by their position along the
food chain ---------CORRECT ANSWER-----------------trophic levels
, All food chains start with this at their base, these organisms transform an
inorganic matter and energy into organic forms. ---------CORRECT
ANSWER-----------------primary producers
How do species coevolve? ---------CORRECT ANSWER-----------------when
an evolutionary change in one species creates a novel selective pressure
that exerts an evolutionary change in another species. The response of the
second species then feeds back to influence the evolution of the first
species. And thus, the cycle continues until neither species has the
heritable variation needed to evolve or they cease to interact.
What is diffuse coevolution? ---------CORRECT ANSWER-----------------a
network of species undergoes reciprocal evolutionary change through
natural selection
What is coevolution? Give an example. ---------CORRECT ANSWER---------
--------Two organisms that evolve in response to each other such as
flowering plants and their pollinators are said to have undergone
coevolution.
What is one on one coevolution? ---------CORRECT ANSWER-----------------
A single species evolves in response to a second species
How do you predict how an interaction between species affects the coevol.
of their niches? ---------CORRECT ANSWER-----------------depending on
how many competition there is already.
