Answer and Explanation:
Parkinson's and Alzheimer's diseases are nuero-degenerative disorders that affect human beings. These are both a form of Dementia, a syndrome that affects the brain, causing symptoms including:
- reduced capacity for multitasking
- memory failure
- issues understanding language
- loss in understanding spatial orientation
Alzheimer's disease is characterized by a loss in these functions, and is eventually fatal, stemming from brain failure. It is genetic and may be influenced by environmental factors like smoking, diet, traumatic brain injury and diabetes among others.
Parkinson's disease is characterized by rigid muscles, tremors, and slowed motion. This may be cased by several non specific conditions such as poisoning, brain damage, head trauma and other complex neurodegenerative diseases.
Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
The correct answer is 'slow down the basal metabolic rate.'The set-point theory suggests that the body lowers the energy expenditure on a restrictive diet to be able to continue functioning normally.
