Aresearcher is comparing the size of sarcomeres in mice to those in elephants. what will he find?
a. sarcomere size is proportional to the size of the animal; sarcomeres of elephants will be much larger than sarcomeres in mice.
b. sarcomere size is inversely proportional to animal size; sarcomeres in mice will be much larger than sarcomeres in elephants.
c. it is impossible to determine sarcomere size in elephants and mice, given that sarcomeres are dynamic and are constantly changing in length and diameter.
d. sarcomere size is relatively constant in vertebrates. as a result, mouse and elephant sarcomeres will likely be equal in size.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
