Answer:

In the brain

Explanation:

These types of drugs work in the brain, more precisely in the central nervous system (CNS) through the control of neurotransmitters ("messenger-like" chemicals of the brain).

Depressants act by decreasing brain activity, while stimulants accelerate brain activity, both by regulating the activity of neurotransmitters(increasing or decreasing).

compare and contrast the processes of photosynthesis and aerobic respiration. how are they similar and how do they differ?
Brut [27]

Answer:

Explanation:

Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.

Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.

6CO2 + 6H20 --------> C6H12O6 + 6O2

Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.

C6H12O6 + 6O2 ------> 6C02 + 6H2O

One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.

The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.

Hopefully this helped! :D
