A student investigated the effect of size on the movement of molecules. He cut three different sized cubes from a block of clear
agar jelly. Cube A was 2 x 2 x 2cm. Cube B was 1 x 1 x 1cm and
cube C was 0.5 x 0.5 x 0.5cm. Calculate the surface area to
volume ratio for all three cubes A, B,C

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
