Biology Review

A population would be considered:

• a group of organisms, same area that interbreed

• a group of different organisms, same area that interbreed

• a group of organisms, different areas that do not interbreed

• a group of different organisms, different areas, that interbreed

Carrying capacity is...

• The minimum number of organisms an Env can support

• The maximum weight a mother gorilla can hold

• The maximum number of organisms an Env can support

• More individuals emigrating out than immigrating in

Which of the following statements is true about Charles Darwin?

• He believed the evolution of a species was due to the inheritance of aquired characteristics

• He was in agreement with Lamarck's theory of how evolution occurred

• He believed that the variation seen within natural populations is the result of repeated mutation

• He believed that those most suited to their environment survive, and given enough time, the species will gradually evolve

What did Lamark believe occurred in regards to how giraffes acquired their long necks?

• Giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks

• It was through random variation that some giraffes had longer necks than others

• The competition between males had driven the evolution of the giraffe neck, with female giraffes somehow carried along as males kept pushing the limits of neck length

• Since shorter creatures pick over food at lower level, giraffes evolved to allow them to reach food and nutrients that others cannot

• The process of plate tectonics and sea floor spreading
