Indicate which pattern of evolution is shown by the many species of finches on the Galápagos Islands.

Answers

Answer;
Adaptive radiation;
The pattern of evolution that is shown by many species of finches on the Galapagos Islands is Adaptive radiation. 

Explanation; 
Adaptive radiation is a pattern of evolution in which a single lineage undergoes multiple speciation events to fill divergent ecological niches. The result is a cluster of phenotypically distinct related species.
A few million years ago, one species of finch migrated to the rocky Galapagos from mainland of Central or south America. From this one migrant species would come many species;-at least 13 species of finch, which exploit different niches, evolving from a single ancestor. 

Answer:

Adaptive Radiation

Explanation:

Adaptive radiation refers to the process of diversification of ancestral line into different forms that occupy diverse ecological niche. The ancestral seed eating stock of Darwin’s finches diversified according to different types of food (plants, seeds, insects, cactus etc) available. They developed type of beak adapted to that food. The geographical isolation led reproductive isolation. Hence, many species of finches on the Galápagos Islands exhibit "adaptive radiation".

If trypsin and chymotrypsin become activated within the pancreas and then are released in their active forms into the bloodstream, why would this represent a potentially life-threatening situation?

Answers

function of trypsin and chemotrypsin:
 these are digestive enzymes present in pancreatic juice and they perform process of proteolysis mean protein break down...
why they are dangerous in blood stream:
as they digest proteins so when they go into blood they can digest all proteins present in blood (like albumin etc) that are very important to carry certain processes..
 

"Since ‘The Simpsons’ is a popular television show, it follows that it has many loyal fans whose viewing habits would be dangerously interrupted if the show were withdrawn. Therefore ‘The Simpsons’ will continue to run at its usual time. From this we may infer that the cartoonist who created the characters will continue to reap the considerable profits generated by this television landmark" is which type of argument?A) simple B) extended, with at most two conclusions C) extended, with more than two conclusions

Answers

Answer:

C) extended, with more than two conclusions

Explanation:

We can state that the argument shown in the above question is an extended argument because it consists of more than one subarguments, which are "Like 'The Simpsons' is a popular television show" and "It follows that it has many loyal fans whose viewing habits would be dangerously interrupted if the show were withdrawn ". Moreover, we can conclude that the argument has two conclusions which are:

  • " Therefore ‘The Simpsons’ will continue to run at its usual time."
  • "From this we may infer that the cartoonist who created the characters will continue to reap the considerable profits generated by this television landmark"
