Dr. kitty hauke is studying lobsters in maine. she noticed that over several years the average length of pincers had increased within this population. she hypothesized that having larger pincers provided a fitness advantage. to test her hypothesis, she introduced 75 large pincer lobsters and 75 small pincer lobsters into an isolated bay area that was similar to the lobsters' natural sea environment. over 10 years, dr. hauke observed this isolated population of lobsters. what would she likely observe if her hypothesis was incorrect?

If the hypothesis was incorrect then the percentage of the large lobsters with large pincers would decrease.

Further information:

How this hypothesis was incorrect?

If her hypothesis was incorrect the percentage of the large lobsters with large pincers would decrease. The large pincers help the lobsters to quickly catch their pray efficiently. This would mean the survival of the lobsters with large pincers. A wrong hypothesis would mean that the large pincer lobsters would die and decrease in number.  

Dominant claw of lobster:

Each lobster has two different claws, a longer crusher claw and a smaller pincher claw. The crusher claw has a ridged edge that look like molars and is used to break up hard food such as clams and crabs. The pincher claw, or ripper claw, is used to scratch apart softer prey such as worms or fish. These claws can be on altered sides of a lobster's body, as the crusher claw is always on the lobster's overriding side.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
