After several days of observing many of his tropical fish die, Biff set out to find out why. He looked at how clear the water was, smelled for any unusual smells in the water, looked at the filter and gathered as much data as his five senses would allow. He finally noticed that the temperature of the water was quite high - around 85 degrees F. He decided to do an experiment to test his hunch on why the fish were dying. He took half of the water from the aquarium and placed it into another clean aquarium along with half of the fish. In the old aquarium he turned the temperature down to 75 degrees F and set the temperature of the new tank at 85 degrees F. The next day he observed that the fish in the original aquarium set at 75 degrees F had no dead fish in it, while the new tank set at 85 degrees F had three dead floating at the

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

All individuals have two alleles for a given trait. according to mendel's these alleles are passed down one each from both mother and father.
