What happens to the neuron when u do drugs

Biology

1 answer:

Furkat [3]3 years ago

Answer:

Explanation:

well different kinds of drugs can affect neuron activity an example is if you take pain pills it blocks the neurons that sense pain other drugs can give you high levels of dopamine, dopamine is the hormone that makes you feel good. that is why drug addictions are serious, and many cannot stop the addiction because it makes them feel good. and if you take the same dose over time your body gets a tolerance to the drug and you need a higher dose every time to get the same feeling and that can lead to an overdose or even death.

The net primary productivity is usually more than 80% of gross primary productivity.

fomenos

Answer:

b. False

Explanation:

As GPP stands for the gross primary productivity, it's the total amount of energy produced in the process and the NPP is the net primary productivity. NPP is the difference between the GPP and the energy used by the producer for the process of respiration.

GPP is a continuous and ongoing process that consumes the energy as compared to the NPP that store energy and not being used. Thus, GPP can affect NPP but NPP does not affect GPP.

For example, GPP is completely being dependent on the chlorophyll content of the plant, but NPP is independent of that content of chlorophyll.

At a point during a cell's development, it begins to differentiate. How does differentiation occur?

Fofino [41]

Explanation:

Differentiation in cells occurs due to the silencing of some genes in the DNA of the cell while leaving others open to RNA polymerase enzymes.

Silencing occurs through the mediation of histones that tightly coil up DNA into heterochromatin in some regions. This way the genes in these regions are inaccessible to transcription enzymes and proteins and cannot be expressed. This means that proteins associated with these genes are not produced.

The open genes, on the other hand, in the euchromatin region, produce the necessary proteins that are associated with the determined function of the cell.

An example is that while the hepatocytes cells and brain cells of the same person have the same DNA, the genes for producing bile are silenced in the brain cells (and are open in hepatocytes) while genes responsible for producing neurotransmitters are silenced in hepatocytes but open in brain cells.

What is the process the does not require oxygen?

erastova [34]

Answer:

The process that does not require oxygen is fermentation.

Explanation:

Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.

The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.

With respect to the other options:

The electron transport chain and the Krebs cycle occur in the presence of oxygen.
