A gene that influences coat color in domestic cats is located on the X chromosome. A female cat that is heterozygous for the gene (X^BX^O) has a calico-colored coat. In a genetics experiment, researchers mate a calico-colored female cat (X^BX^O) with an orange-colored male cat (X^OY) to produce an F1 generation. The researchers record observations for the cats in the F1 generation
and plan to use the data to perform a chi-square goodness-of-fit test for a model of X-linked inheritance. The data for the chi-square goodness-of-fit test are presented in Table 1.

The researchers calculate a Chi-Square value of 4.6 and choose a significance level of p=0.05. Which of the following statements best completes the Chi-square goodness-of-fit test?
A) The null hypothesis can be rejected because the Chi-square value is greater than the critical value.
B) The null hypothesis can be rejected because the Chi square value is less than the critical value.
C) The null hypothesis cannot be rejected because the Chi-square value is greater than the critical value.
D) The null hypothesis cannot be rejected because the Chi-square value is less than the critical value.

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
