The lack of change in such organisms is most likely because A) the environment that they lived in remained the same, and they were well-adapted to it B) all members of their population were genetically identical, and they lived in a rapidly changing environment C) there was a large amount of variation in their population, and the environment changed frequently D) they could move between different environments when food supplies became scarce

Fossils can only be formed when? if mud, silt or tar is in the area to preserve the fossil ierosion does not occur and allows the fossil to form oxygen and microorganisms cannot decay the bones the area is dry and does not contain mud or silt

Ais a landform that is formed at the mouth of a river from the deposition of sediment carried by the river as the water flows.

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
