<span>Animals gradually adapt to changes within their environment over time. This gives them a better chance of surviving rather than going extinct because of the change. Say there is a gene mutation affecting color within a population of beetles in a rain-forest. All of the beetles used to be red, but now a few of them have experienced a gene mutation and are green. Because they live in a rain-forest, it is likely that the green beetles would blend in with their surroundings far better than the original red beetles, and those red beetles would be wiped out by predators because they are easier to spot. The green beetles would live on and flourish, and their population would increase. Soon there would be few or none red beetles, and many green beetles.</span>
The effect of methylphenidate (ritalin) on the synapse is most similar to the action of other appetitive drugs such as amphetamine/ dextroamphetamine (Adderall).
<h3>What are appetitive drugs?</h3>
- An appetite stimulant or orexigenic is a drug or compound which increases the appetite and may also induce hyperphagia.
- These can be taken in the form of medications that increase hunger and enhance food consumption.
- Methylphenidate is in a class of medications called central nervous system (CNS) stimulants as they influence the CNS to eat more.
- Side effects of this medication include increased blood pressure, palpitations, appetite increase which may lead to weight gain.
- Methylphenidate is used to treat attention deficit disorder (ADD) and attention deficit hyperactivity disorder (ADHD) as it affects chemicals in the brain and nerves that help to control hyperactivity and impulse.
