Terminology
What is the direction of Latitude?
North to south of the equator
In lakes, photosynthesis occurs primarily in which of the following zones?
limnetic
True or false? "A river that divides 2 populations of the same species, is referred to as a biological barrier."
False its a geological barrier
A random mutation or change in the genetic code within a cell can?
occur spontaneously
Which domain contains organisms within the kingdoms fungi, protista, animalia and plantae?
Eukarya
An ecological niche of a population is best described as the population's?
role of the organisms within the ecosystem
The energy for marine organisms in the aphotic zone primarily comes from
detritus
Which of the following is an abiotic factor in a biome?the kinds of trees or the average temperature
the average temperature
Evolution within a species happens more slowly if?
there is an abundance of resources and very little competition.
What are the 4 factors that create climate?
1.Air currents
2.Circular water flow
3.Continents
4.Mountains
When classifying organisms, the most broad (or least specific) level of classification is a
Domain
What symbiotic (mutualistic) organism is housed within reef-building corals?
photosynthetic algae
"The prairie landscape that stretches from Edmonton to Winnipeg is known to ecologists as the aspen parkland – a transitional zone from prairie to boreal forest."
This would be a description of Edmonton's
biome
"A song bird changes his mating song. This results in some females not mating with males with the old song."
This description is an example of
a biological barrier
At higher or lower latitudes, sunlight strikes the Earth at a
slant resulting in lower average temperatures.
Taxonomy is the process of
categorizing living and ancient organisms.
A eutrophic lake has
lots of organic matter entering it all the time, but low oxygen
What is a biome?
identifies organisms based on their visible characteristics.
According to Lamarck, if an individual spends a lot of time outdoors and has very tanned skin, then their offspring are more likely to
be born with darker skin.
Transitional fossils best serve as evidence for evolution because they show
the intermediate steps in the evolution of a species.
What is Analogous?
Anatomically different structures that have a similar function . organisms with analogous structures do not share a common ancestor
In the photic zone of the ocean the main source of energy is
sunlight
A specific terrestrial biome that contains the greatest biodiversity on earth is the
Tropical rainforest
A population within a studied species will evolve MOST quickly if
the population reproduces more quickly
The Earth is generally hotter at the equator because
the Sun’s rays strike the Earth at a right angle at the equator.
