Recent research into mutation involved finding the base
sequence of all genes in parents
and their offspring. It showed that
there was one base mutation per
1.2 × 10^8
bases. Calculate how
many new alleles a child is likely
to have as a result of mutations
in their parents. Assume that
there are 25,000 human genes
and these genes are 2,000 bases
long on average.

because they are eaten by the frog and the frog getseaten by the snake and the snake by the eagle

answerbloodstream;

reflection is the bouncing back of a propagating wave when it encounters a barrier; usually shows an image of the source of light wave

1) bounces back from an opaque material

2) bounces back from the boundary

3) seen in mirrors

refraction is the bending of a propagating wave having a shift of direction as it passes through different media; usually seen in lenses to magnify or lessen

1) passes through a prism

2) moves from one medium to another

3) seen in lenses

the answer is either a. or d. if you're talking about fully electric cars, then the answer is a. if you're talking about hybrid cars, the answer would be d.
