Answer:
option A. the factors separate
Explanation:
The Mendel referred alleles as factors. Mendel was unaware about gene but he knew that there are two factors for a single character. The single factor gets transferred from each parent. The gene contains two alleles/factors. The alleles/factors from both mother and father separates at the time of formation of gametes. These gametes from both parents containing alleles/factors recombines and thus forming a zygote.
Thus, factors separate during gamete formation. So, option A is correct.
Not sure but hope this helps!
Multimedia. Water boils in a flask, and later the flask is
stoppered and removed from the hot plate. When ice
water is poured over the flask, the water begins to boil.
When the flask is cooled, the pressure of the water
vapor decreases, which decreases the boiling point of
the water.
When Hana pours the mixture through a filter,
she will likely to collect a solution of salt in water that passes through the
filter. <span>The activity shows the split-up of solids that
are not soluble from a liquid by means of what we called filtration. It can be
used to separate solids that are not soluble from a liquid, or a precipitate
from the reaction mixture that it made. </span>
Scientists developed the time scale by studying rock layers and fossils world wide.
Radioactive dating helped determine the absolute divisions in the time scale. so mass extinction help because there is more to study
