In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. ... Chlorophyll then replaces the lost electrons from water molecules. The oxygen atoms form oxygen gas while the hydrogen atoms form protons and electrons.
Answer:
Probability is the chance that a given event will occur. The principle of probability allows us to predict the possible combinations of phenotypes in a genetic cross by using a diagram called Punnett squares. This diagram represents alleles and gives us the genetic variations formed during a cross. For example, a flower has one dominant allele for a blue color, which is represented by capital T, and one recessive allele for a pink color, which is represented by small t. When this flower is crossed with another flowering plant with the same type of alleles, which is Tt, the combinations produced for their offspring includes TT, Tt, tT, and tt.

The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
Stars begin to form from clouds of gas in space. The cold temperatures and high densities (compared to elsewhere in space, but would be considered a vacuum on Earth) of these clouds allow gravity to overcome thermal pressure and start the gravitational collapse that will form a star.
