The many finch species of the Galapagos Islands evolved from a single species that immigrated to the islands from the coast of South America. These species differ primarily in beak shape, which is closely related to the type of food each species specializes in eating. Which of the following best explains why each finch species on the Galapagos islands evolved to be specialists? A) Islands have limited food resources, forcing species to feed on a small range of food items.
b) Climate on islands tends to be less variable than on the mainland, minimizing seasonal absences of food.
c) Reduced Competition from other bird species allows finish species to focus on specific food resources.
d) Food resources on islands are more plentiful and nutrient rich than on the mainland, leading to specialist behaviors in feeding.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
