Myopathy (CNM) is genetic disease in Labrador retrievers that results in
insufficient muscle function, poor muscles tone, exercise intolerance, and
awkward gait. CNM only develops in dogs

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?
percent of lobsters with large pincers would decrease.
were fewer small pincer lobsters mating during mating season.
large pincer lobsters could be found mating during mating season.
percent of lobsters with large pincers would increase.

At the beginning of the
spring, Dr. Allan notices that there is an equal distribution of long and
short stemmed buttercups in the vacant lot (which is never cut) across the
street from his house, as well as in his own backyard. By the end of
the summer he notes that there are mostly long stemmed buttercups in the
lot, but mostly short stemmed buttercups in his yard, which he regularly
mows. These observations are examples of what biological
principle? Develop a hypothesis to explain Dr. Allan’s observations.
