Answer:

only sympathetic fibers can regenerate accurately

Explanation:

Neuroregeneration is a complex biological process associated with the regrowth and/or repair of nervous tissues. This process depends on the type of nerve tissue and how seriously the nerve was injured. The autonomic nervous system, also known as the autonomic nervous system (ANS), is part of the peripheral nervous system (PNS) that is responsible for regulating involuntary physiological processes. The PNS contains two basic divisions: sympathetic and parasympathetic. The sympathetic fibers innervate tissues in nearly all the organ systems and they are responsible for regulating homeostatic processes (e.g., heart rate). The sympathetic nervous system is formed by nerves from the thoracic and lumbar segments of the spinal cord. These autonomic nerves can regenerate after injury in order to reinnervate target tissues (e.g., after chronic cardiac ischemia).

Which group of non-prokaryotic organisms studied in microbiology typically have two life cycle stages: trophozoite and cyst?
uranmaximum [27]

The correct answer is Protozoa.

A class of single-celled, non-prokaryotic organisms known as protozoa.These could either be parasitic or free-living in nature. These are heterotrophs that procreate via binary fission in an asexual manner. Numerous unrelated or tangentially related organisms make up the Protozoa. Sarcodina, Flagellates, Ciliates, and Sporozoans are the four main divisions. There are two stages in the life cycle of certain protozoa: the proliferative stage (trophozoites), and the resting stage (cysts). Trophozoites are the proliferative stage of the protozoa, which is when they divide and reproduce. The protozoa can tolerate adverse environmental circumstances like toxic chemicals, intense heat, and nutrition and water shortages because of their resting cyst shape.
