The correct answer for this question would be the second option. The one who invented he polymerase chain reaction (PCR) that allowed scientists to enlarge and study genetic material is Kary Mullis. PCR is <span> a technique that amplifies specific DNA sequences from very small amounts of </span>genetic material<span>. Mullis invented this while he is at Cetus. </span>
Solar eclipses occur more often than lunar eclipses because in a lunar eclipse, the moon has to be perfectly aligned with both the earth and the sun.
Solar eclipses occur about 2 to 4 times per year, but the area
on the ground covered by totality is only about 50 miles wide. In any
given location on Earth, a total eclipse happens only once every hundred
years or so, though for selected locations they can occur as little as a
few years apart.
Eclipses of the Moon by the Earth's shadow occur less often than solar eclipses, however, each lunar eclipse is visible
from over half the Earth. At any given location, you can have up to
three lunar eclipses per year, but some years there may be none.
In any
one calendar year, the maximum number of eclipses is four solar and
three lunar.
The factor given in the choices that will probably decrease population density would be C. forest fire. Normal rainfall is beneficial to the ecosystem to help grow the vegetation and in result, benefits the consumers. Predators decrease the population while birth rate can also increase population.
