Hello,
Your answer would be:
Stem cells come from an early embryo and these are divided into three types which are Embryonic stem cells, tissue stem cells and Induced pluripotent stem cells, or ‘reprogrammed’ stem cells. Currently, stem cells are being used in the laboratory for clinical trials to provide new therapies and other possible ways for treatments for certain diseases. Hope this answer helps.
Here’s the answer to your question would be:
They replace old neurons with new ones.
Here’s a article from the internet:
“Today, most treatments for damage to the brain or spinal cord aim to relieve symptoms and limit further damage. But recent research into the regeneration mechanisms of the central nervous system, including the discovery of stem cells in the adult brain that can give rise to new neurons and neural support cells, has raised hopes that researchers can find ways to actually repair central nervous system damage. Research on stem cells in nervous system disorders is one of the few areas in which there is evidence that cell-replacement therapy can restore lost function.”
Plz mark me brainliest!
Hope this helps!
They also treat disorders
Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming
Answer:
Tryptophan synthesis enzymes be made during low level of cellular tryptophan.
Explanation:
Tryptophan operon contain 3 regulatory gene(trpR,trpP and trpO) and 5 structural genes(trpE,trpD,trpC,trpB and trpA) .trpR encodes the repressor protein that interacts with tryptophan present in the media and then the tryptophan repressor complex binds to the operator region to block the transcription of the structural genes of tryptophan operon.
Here tryptophan acting as a corepresor.During mutation of trpR gene tryptophan biosynthesis enzymes will be synthesized only when the cellular tryptophan level remains very low.
