Several species of finch live on the Galapagos Islands. They are very similar in appearance, but have adapted beaks of different
sizes and shapes based on their major food source. Finches with large beaks eat mainly large seeds and cacti. Finches with small
beaks eat mainly small seeds and insects.
Which of the following best explains the variety of beaks found in finches on the Galapagos Islands?
O A.
Biological evolution only affects the species diversity of plants in an ecosystem.
OB. Evolution through natural selection always causes a decrease in the species diversity of an ecosystem.
OC.
Biological evolution does not have any effect on the species diversity of an ecosystem
OD.
Evolution through natural selection can increase the species diversity of an ecosystem.

Are salt and soap nutrients or toxins for yeast? explain.

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna.nothing should be altered.the ph should be decreased.the temperature should be raised.
