Answer:
False. The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was food availability.
Explanation:
Finches speciation was due to geographical isolation on islands and the differences in their picks were an evolutive adaptation that reflected feeding habits. Their speciation depended on or was the result of their adaptation to the island and its characteristics. The finches´ beaks evolved according to food availability. Large beaks are better for islands with larger seeds, while pointed beaks are better for getting insects out of trees.
Based on the broth left on an open flask experiment, wherein the boiled broth was placed in two flasks (one flask with straight neck and the other flask has a bent neck) and exposed to open air at room temperature for several weeks.
The broth within the straight neck flask has changed its appearance. It became discolored and cloudy. Whereas, the broth in the bent neck open flask still remains the same.
These results would then support the conclusion that germs in the air were able to fall unobstructed towards the straight neck flask and contaminate its contents. While, the bent neck of the 2nd open flask acted as a trap for the germs, preventing the germs from contaminating the broth. Further emphasizing that germs can only come from other germs and not from spontaneous generation.
B, because species b has a higher percentage of survivors to old age than species C. Species a still has a higher rate than species C so the answer is b.
Answer:
I would say B
Explanation:
Selective breeding is done to achieve desired traits, while Natural Selection is done without human involvement.
