On which part of the body does long-term use of stimulants (e.g., nicotine, cocaine, and methamphetamine) have the most signific
Y_Kistochka [10]
Stimulants are substances that all result in the increase of levels of dopamine in the brain, which is a neurotransmitter that affects attention and pleasure. What this means is that stimulants affect our brain and the way it works by changing the ways that nerve cells communicate.

Neurons (nerve cells) are the cells that have a role in transmitting messages from the brain to other parts of our body, and vice-versa, which is important for pain response, alertness, energy etc.

With long-term use, the use of stimulants would affect the central nervous system (speeding it up), the brain, and the functions necessary to live, like respiration, heart rate, blood pressure, body temperature. Levels of neurotransmitters like dopamine, serotonin, and GABA, which are responsible for the regulation of different processes,  are also impacted, which creates a chemical disbalance ultimately resulting in behavioral changes, mood swings, altered attention, movement and energy, stress etc.

So the part of the body that is affected the most with the long-term use of stimulants like cocaine, nicotine, methamphetamine is the brain of course, which is where these substances have the most impact, but the impact on the central nervous system, autonomous nervous system, and neurotransmitter levels is significant.

How do clouds help protect our planet?​
Inessa [10]
Clouds can block light and heat from the Sun, making Earth's temperature cooler. You've probably noticed this kind of cooldown on a cloudy day. However, some heat from the Sun does get down to Earth. Clouds can trap that heat from the Sun.

Although it is not the primary flux-control point for glycolysis, pyruvate kinase is subject to allosteric regulation. What is t
deff fn [24]

Answer:

Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.

The regulation of the pyruvate kinase is done by the allosteric regulation and   fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
