Humans have typically 23 pairs of chromosomes. Each pair is composed of a chromosome from the mother and another from the father. A specific locus in a chromosome is composed of two alleles. An allele inherited from the mother and the other allele inherited from the father.
Photosynthesis uses sunlight energy to make glucose (energy stores). A by-product of photosynthesis is oxygen. plants use water and sunlight to grow and they produce oxygen. Animals eat plants, use oxygen and breathe out carbon dioxide. Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. Therefore the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.
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.
