Suppose you have made the following hypothesis:

the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up.
if you observed that two identical balls, dropped from the same height, each reached the ground with a speed of 3 m/s, does that evidence support the hypothesis?
a. yes, the evidence supports the hypothesis.
b. no, the evidence contradicts the hypothesis.
c. the evidence is not related to the hypothesis.

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?

Dna. we have heard that we are a product of our dna. but where is it? how do we "get" our dna? it is passed to us, from our parents, but in what form? several vocabulary words associated with inheritance are used interchangeably and sometimes, incorrectly. let's see if you can clear this up for someone just learning about inheritance and cell structure.

What enzyme is most important for dna replication and why?
