How do petrified fossilization differ from carbonized fossils? Petrified fossils do not need carbon to be fossilized.
Petrified fossils are only made in desert type environment.
Petrified fossils need a lot of carbon in order to be come a fossil.
Petrified fossils dissolve all original parts including carbon.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.

The big bang theory suggest that the universe is about - 300 million years old - 4.6 billion years old - 30 billion years old - 13 billion years old
