The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>
Explanation:
The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).
The PNS is divided into somatic and autonomic nervous systems.
The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.
The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.
Cells of the skin and digestive tract are continuously sloughed off and replaced by new ones due to mitotic division.
Some body parts of animals and plants can be regenerated by mitotic cell division.
Vegetative propagation in plants and budding in some animals also occurs due to mitosis.
Answer:
pH meter and pH paper.
Explanation:
There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.
The regulation of the bodies internal environment is called homeostasis. And there are so many ways that affect homeostasis in the human body and to name three: first is the heat where we seat when we get too hot. Second, is the cold where we shiver when we get too cold and the third is the fluid intake where dehydration can kill.
Answer: THEY ARE INVOLVED IN THE DISASSEMBLY OF THE NUCLEAR ENVELOPE
Explanation: The disassembly of the nuclear envelope is triggered by the cyclin‐dependent kinase at the onset of mitosis. At this point, Integral nuclear membrane proteins diffuse/move into the endoplasmic reticulum (ER) after nuclear envelope breakdown. The nuclear envelope reassembles around compact chromosome mass at late anaphase/telophase and the chromosomes condenses and become visible.
