The correct arrangement of steps that occur in producing neuron cells.
The steps are from 1 to 4 according to arrangement.
- Genes that lead to the production of undifferentiated precursor neurons are activated.
- Stem cell arise from the inner mass of cells.
- Signalling factors trigger differentiation in stem cells.
- Signalling factors causes precursor neurons to produce neurons.

Answer:
One of the most common Monera is Escherichia coli, also known as E. coli. "[E. coli] is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms." States ________.* Signs of E. coli are stomach pains and cramps, diarrhea that may range from watery to bloody, fatigue, loss of appetite or nausea, vomiting, and low fever < 101 °F/ 38.5 °C (not all people have this specific symptom).
E. coli comes from human and animal wastes. During precipitation, E. coli may be washed into creeks, rivers, streams, lakes, or groundwater. Another way to get it is from contaminated food, a lot like corona virus. When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. And when ground beef is made, it combines meat from many different animals, increasing the risk of contamination.

Isotonic solution
This is a solution in which there is no net movement of water into our out of the cell when a cell is placed in this solution. The solution is also dilute.
These minerals are quartz, feldspar, mica, and usually hornblende. Granite forms as magma cools far under the earth's surface. Because it hardens deep underground it cools very slowly. This allows crystals of the four minerals to grow large enou
