Solar energy is a form of renewable energy, namely energy that cannot be depleted. Other forms of energy like carbon based sources of energy cannot be renewed in a reasonable span after being used (forests take time to grow and oil is created in geological timescales). Joe is trying to deal with the phenomenon of resource depletion. The way he goes about it is making a renewable source of energy more efficient and usable.
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
A chromosome deletion occurs when a chromosomal fragment is lost. Thus the chromosome is missing some genes. One example of this in humans is know as cry of the cat. It occurs from a deletion on a chromosome number 5. A child that is born has a mental disability a small head with unusual facial features and cries like the sound of a distressed cat. The children rarely live into adulthood.
