PL HELPPP CANT GET WRONG PLSSS HEL If the weather in Chula Vista changed to very cold (snow on the ground 8 months of each year) over the next few years, what change might occur?

A. The cold weather would cause a mutation in squirrels which causes their fur to be white.

B. If a mutation occurred which caused white fur to develop, the white squirrels would have a better chance to survive and produce more offspring with the characteristic.

C. Natural selection would cause a new genotype to appear in the population, resulting in squirrels with white fur.

D. Evolution would definitely occur resulting in white squirrels.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
