Answer:
The solar eclipse
Explanation:
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. ... But lunar eclipses do not occur every month because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun.

The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
Phenotype is the physical appearance
Genotype is the traits in letters.
lets say green eyes...
having the gene GG, Gg, except gg will yield green eyes
so, if you see someone with green eyes, he/she must either have two dominant trait or 1 dominant and 1 recessive trait. Since you gave to us that an organism expresses a recessive phenotype, you can automatically tell that the person will have 1 dominant and 1 recessive, or Gg.
However, if that is not given, you wont be able to tell the genotype based on looking at a person.
