How can scientists predict the muscle size of an animal? O Scientist can make inferences based on the location fossils are found.
O Some fossils contain muscle tissues.
O Scientists can make inferences based on the type of climate that animal lived in.
O Bone scars give clues about the muscle size.

THIS IS ABOUT FOSSILS

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.

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. assume all are homozygous. chinchilla x albino a) all chinchilla b) 1/2 chinchilla, 1/2 albino c) 3/4 chinchilla, 1/4 albino

The first generation of offspring from the cross of two parents is called the a.f1 generation b.f2 generation c.short generation d.p generation
