Question
Part 1-:
What would the Hjülstom’s diagram for wind look like?
a) it would be similar to the one shown for water but with higher wind velocities required for transport. This is because water is more dense than air.
b) this principal can’t be applied to wind.
c) the top line would be horizontal for the Hjülstom’s diagram of wind.
d) the two lines would intersect each other.
Part 2-:
Which of the following is a common fossil?
a) stromatolite
b) granite
c) broyoza
d) limestone
e) both a and c are fossils.
Part 3-:
Which of the following is an example of convergent evolution?
a) small marsupials on Pangea were separated by continental drift. These animals evolved into different species based on their differing environments.
b) Darwin’s finches were found on the Galapagos islands. They all had a close common ancestor, but had developed different structures to adapt to the environmental pressures on their island. They eventually became different species that were no longer able to interbreed.
c) the pronghorn of North America closely resembles the antelopes of Africa and Eurasia, both behaviorally and morphologically. They both occupy a similar ecological niche and are found in similar biomes.
d) the kit fox lives in the desert and the red fox lives in the forest. The kit fox has developed a white coat to help it avoid predation and large ears to help cool it more easily, while the red fox has a red coat and smaller ears.
e) both a and c describe convergent evolution.
Part 4-:
In which of the following fossil types, can some of the internal structures remain intact?
a) cast
b) mold
c) petrified fossils
d) all trace fossils
e) all of the above
Part 5-:
Which of the statements about fossil evolution is true?
a) divergent evolution is seen in species with very different origins that begin to evolve similar characteristics.
b) index fossils are used to define relative time.
c) in general organisms evolve from complex to simple forms.
d) each evolutionary stage may be recorded in the fossil record.
e) both b and d are true.
