Answer:
Adaptation and extinction occur as a result of long term change whereas loss of habitat and forced migration results of short term change.
Explanation:
Adaptation and extinction occur as a result of long term change in the environment whereas loss of habitat and forced migration is a result of short term change in the environment. Adaptation occurs in the organism as a result of climate change because when the climate change occurs some organisms are extinct due to intolerance of the change environment whereas some organisms adapt the environment by making some changes its physical structure in order to survive. Loss of habitat and forced migration occurs due to sudden big change in the environmental conditions such as flooding and volcanic eruptions.
Answer:
D) sympatric speciation and habitat isolation
Explanation:
Sympatric isolation is a form of evolutionary process whereby different species from an ancestral origin evolve within the same geographical environment as a result of reproductive isolation.
Habitat isolation is a form of reproductive isolation which occurs when two populations of a species inhabiting overlapping habitats become unable to interbreed with each other.
Reproductive isolation (habitat isolation) that occurs in the fleas is as a result of the new species becoming separate from it's ancestral species which feed only on pronghorn antelopes, although both species can still be found in the same geographical location (rangeland). The new species now have preference for cattle blood, and so are now found on cattle.
In the situation of the two new species of flea that would evolve, it can be said to an example of sympatric speciation and habitat isolation, since the host mammal is assumed to be their habitat and both the cattle and pronghorns often associate with one another in the same open rangeland.
I would say B) 1-3 hours because Bacteria can multiply anywhere between 20 to 30 minutes and if it doubled in size 1-3 hours would be the most reasonable option!
Yes all living organisms need sun to survive
