Answer:
Neurodegeneration
Explanation:
The term neurodegeneration refers to a group of disorders which are characterized by a progressive waste of function or structure of neurons, that in worst cases can include death of neaurons.
Many neurodegenerative disorders such as Parkinson's disease,– including amyotrophic lateral sclerosis, Huntington's disease and Alzheimer's disease can occur due to neurodegeneration.
Neurodegeneration can manifest itself in various forms such as lack of physical and intellectual abilities like inability to use muscles or memory loss. These disorders cannot be completely cured and ultimately lead to the death of neurons.
As mentioned in the question, the person suffers from progressive loss of intellectual and physical abilities that has occurred over the course of a long period of time. Therefore, it is most probable that he is having some neurodegenerative disorder.

Answer:
Mendel also experimented to see what would happen if plants with 2 or more pure-bred traits were cross-bred. He found that each trait was inherited independently of the other and produced its own 3:1 ratio. This is the principle of independent assortment .

Answer:
<em>Thermotoga maritima</em> is a bacterium that have similar genes of most of the archaea that live in similar extreme environment is most likely the result of lateral gene transfer.
Explanation:
This bacteria contain certain genes that are extremely similar with the genes that are present in archaea. This is a example of lateral gene transfer where acquisition of genetic material takes place by another organism without being it's offspring.
Prokaryotes can exchange genes under highly selective condition through lateral gene transfer that enters in to the body of diverse bacteria where the genes involve in several functions like metabolic function, transport of energy transcription, gene regulation etc.
Answer:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
