The name given to the original cell before it divides is called the parent cell.
Using a molecular clock, scientists are able to estimate the amount of time that two species have been evolving independently.
Hope this helps :)
The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.
Answer:
The correct answer would be levodopa/carbidopa.
Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.
These drugs are used to treat the symptoms of Parkinson's disease.
Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).
In the brain, levodopa is converted into dopamine which helps in controlling the movement.
Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
