Biodiversity in the Cenozoic QUESTIONS
AND ANSWERS
1. A land bridge paperwork between North and South America at some stage in this time
(the Isthmus of Panama). Before this time, North and South America had been separate,
and an east-west ocean contemporary flowed among them. After North and South
America were linked, ocean currents were forced to glide north-south. The warm waters
of the Gulf Stream now waft north along the east coast of North America and over to
Europe. What affect did this have on weather in North America and Europe? -
ANSWER-hotter/wetter weather
2. Analogous systems evolve independently. They are comparable structures that seem in
organizations of organisms. Are these systems a result of BIOLOGICAL or
CONVERGENT evolution? - ANSWER-convergent
3. ANALOGOUS STRUCTURES: - ANSWER-Similar systems that appear in
businesses of organisms because of convergent evolution.
4. Antarctica separates from Australia at some point of this epoch and a chilly circumpolar
ocean present day forms (a modern-day around Antarctica). This bloodless water
present day cuts off warmer water from circulating close to Antarctica. Cold water cools
the air above it. Will the amount of glaciers on Antarctica INCREASE or DECREASE? -
ANSWER-increase
5. Antarctica separates from Australia for the duration of this epoch and a cold circumpolar
ocean present day forms (a present day round Antarctica). This cold water present day
cuts off hotter water from circulating close to Antarctica. Cold water cools the air above
it. Will this cause a HIGHER or LOWER global sea degree? - ANSWER-decrease
6. Antarctica separates from Australia during this epoch and a chilly circumpolar ocean
contemporary forms (a current round Antarctica). This cold water modern-day cuts off
hotter water from circulating close to Antarctica. Cold water cools the air above it. Will
this WARM or COOL climate of Antarctica? - ANSWER-cool
7. Are the enamel all of the equal form in Dimetrodon? - ANSWER-sure
8. Are the tooth all of the identical form in Gorgonopsid? - ANSWER-yes
9. Are the teeth all the identical size in Dimetrodon? - ANSWER-no
10.Are the tooth all of the equal size in Gorgonopsid? - ANSWER-no
11.are the teeth within the cynodont the equal shape? - ANSWER-no
12.are the enamel inside the cynodont the identical length? - ANSWER-no
13.Are the enamel of cynodont and the bat are ANALOGOUS or HOMOLOGOUS? -
ANSWER-HOMOLOGOUS
