Skin color in a certain species of fish is inherited via a single gene with four different alleles. One fish of this type has alleles 1 and 3 (S1S3 ) and its mate has alleles 2 and 4 (S2S4 )

B) 1/8
C) 1/2

You collect and measure samples of ice and surrounding ice water from a stream in the winter. You find that you collected the same number of water molecules in each form. The volume of the ice samples are larger than the ice water samples. This is a result of
A. the ionic bonds between the water molecules being unstable and constantly forming and breaking that increases the volume and decreases the density of the ice. B. the covalent bonds between the water molecules being unstable and constantly forming and breaking that increases the volume and decreases the density of the ice. C. the covalent bonds between the water molecules being in a fixed position that increases the volume and decreases the density of the ice. D. the hydrogen bonds between the water molecules being unstable and constantly forming and breaking that increases the volume and decreases the density of the ice. E. the hydrogen bonds between the water molecules being in a fixed position that increases the volume and decreases the density of the ice.
