. Place both coins in cupped hands, shake, and then toss the coins onto your desk. Read and record the letter combination in column C (Toss Results) of Table 1. Make a slash (/) in the proper row of column C to indicate the letter combination. Repeat this process until the coins have been tossed 100 times. Record the coin combinations for each toss in Table 1. list in column A of Table 2 the number of offspring expected to have normal skin color (SS and Ss) and the number expected to be albino (ss). • Calculate the number expected to have each trait if there are 100 offspring. Do this by multiplying column A figures by 25. Record these numbers in column B of Table 2. . Record in column D the totals for each. Part C. Determining Numbers of Expected Phenotypes . Assume that S represents the dominant gene for normal skin pigment. Assume that s represents a recessive condition called albinism, no skin pigment. From the Punnett square (Figure 1), Part D. Determining Numbers of Observed Phenotypes From your data in column D of Table 1, total and record in column c of Table 2 the number of offspring who will have normal skin pigment (SS, Ss, and ss) and those who will be albino (ss). TABLE 1. EXPECTED AND OBSERVED GENOTYPES (A) (B) (C) EXPECTED EXPECTED GENOTYPE FOR GENOTYPE FOR TOSS 4 OFFSPRING 100 OFFSPRING RESULTS (D) GENE COMBINATION OBSERVED GENOTYPE FOR 100 OFFSPRING SS Ss or ss SS

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.
