The speed of light is 1.90 times larger in material A than it is in material B. Determine the ratio nA/nB of the refractive indices of these materials.

A convex lens has a focal length f. If an object is located at 2f, at what distance from the lens is the image formed?

A thin convex lens has focal length f. An object is placed a distance (5/2)f from the lens. At what distnce from the lens is the image formed?

A coil of wire with a resistance of 0.45

How many introns does this predicted mRNA have? 

  One degree of freedom is used for an n of 2.

Cat coat color involves multiple epistatic interactions. Use the Table menu option on your answer box below to make a 5×5 grid. You will use this and the information below to work a punnet square for the following dihybrid problem. Complete an F2 Punnet square for the P1 parents listed. Cat Genotypes and Associated Phenotypes Agouti (A_) is dominant over Solid (aa) Black (B_) is dominant over Brown (bb) and both are dominant over Cinnamon (b’b’) Temperature Sensitive Colorpoint (C) genes (siamese, etc.) are epistatic to color genes (A, B or O): C_ no colorpoint is dominant over c’ Burmese and c” Siamese , which are co-dominate (c’c” = Tonkinese). The albino allele is recessive to all other colorpoint alleles. Non-dilute (D_) is dominant over dilute (dd). The dilution allele is epistatic to color (B or O) – Creates Blue from Black, Lilac from Brown, Sable from Cinnamon, and Cream from Orange. Normal (E_) pigmentation is dominant over Amber (ee) and this gene is epistatic to color genes (A, B or O) Orange (O- or OO) is X-linked and co-dominant (tortoiseshell in female heterozygotes). The Orange/tortiseshell gene is epistatic to Color (A, B). Dominant White (W_) is epistatic to Colorpoints (Locus C), Agouti (Locus A), Color (Locus B), Orange (Locus O), Dilute (Locus D) and Amber (Locus E). WW is linked to deafness. Note that W_ is a different gene than the Albino cc locus.  How does X-linkage result in a hemizygous condition in males?

A child selects 3 toys from a box WITHOUT replacement. The box contains 7 toy cars and 9 toy animals. Let the random variable X be defined as the number of toy cars selected.  Which probability distribution table below correctly represents the number of toy cars selected?  TABLE A  Number of Toy Cars p(x) 0 0.35 1 0.25 2 0.175 3 0.225   TABLE B  Number of Toy Cars p(x) 0 0.15 1 0.45 2 0.3375 3 0.0625   TABLE C  Number of Toy Cars p(x) 0 0.30 1 0.525 2 0.175   TABLE D  Number of Toy Cars p(x) 0 0.43784 1 0.17856 2 0.3836
