<h3>What is bacteria?</h3>

Bacteria are common, primarily free-living creatures with only occasionally one biological cell. Bacterium is the singular form. They account for a large chunk of the prokaryotic microbial kingdom. The bulk of the ecosystems on Earth are home to bacteria, which are typically a few micrometers long and were among the first life forms to emerge there.

Bacteria can be found in soil, water, acidic hot springs, radioactive waste, and the deep biosphere of the Earth's crust. Bacteria play a crucial role in several stages of the nutrition cycle by recycling nutrients like nitrogen from the atmosphere. The nutrient cycle includes the breakdown of dead bodies; microorganisms are in charge of the putrefaction stage of this process.

<h2>Neural crest </h2>

Explanation:

The neural crest likely forms: neurons and glia of the peripheral nervous system

  • The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
  • In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
  • The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
  • Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
  • Glia are also essential to nervous system function, but they work mostly by supporting the neurons
