Galactosemia can result from a deficiency of either galactokinase or UDP-glucose:galactose 1-phosphate uridylytransferase (transferase). Although a deficiency of either enzyme will cause gastric discomfort after milk ingestion, transferase deficiency also results in liver, kidney, spleen, and brain dysfunction, and in some cases, death. Select the statements that correctly link each type of enzyme deficiency with the metabolites that accumulate in the blood and tissues

a. A deficiency in either enzyme will result in an accumulation of lactose; however, a transferase deficiency will also cause an accumulation of the toxic product UDP-galactose
b. A transferase deficiency will result in an accumulation of the toxic metabolite galactosse 1-phosphate.
c. A galactokinase deficiency will cause an accumulation of galactose.
d. A galactokinase deficiency will result in an accumulation of galactose 1-phosphate
e. A transferase deficiency will cause an accumulation of UDP-glucose.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

2. if someone had the list of traits you provided in question 1, do you think he or she would be able to find you in a group of 1000 people? why or why not? if not, what other information encoded in your genes might distinguish you from the others in the group? what are other traits that are encoded for by dna?

Explain why biological control methods are generally environmentally superior to chemical pest control methods.
