Answer:
A. Preganglionic sympathetic fiber
Explanation:
The fibers of the central nervous system (CNS) that innervate the parasympathetic ganglia are referred to as preganglionic fibers. For example, preganglionic nerves are found in the airways, and function for controlling the breathing movement. Both parasympathetic and preganglionic sympathetic fibers use acetylcholine as neurotransmitter (i.e., they are cholinergic fibers) and are myelinated. Moreover, different vasoactive mediators including histamine and prostaglandin are able to improve ganglionic cholinergic transmission.
A spacecraft that is not traveling at an orbital velocity will:
a. get attracted into a different kind of gravity or pole
b. will become off-set and be lost within space
This is the main reason why spacecrafts are well computed mathematically and engineering wise in order for it to travel and perform its roles in space.
Answer:
Body temperature
Explanation:
We use body temperature as homeostasis parameter in the lab.
Homeostasis can be described as a self regulating mechanism used by the body systems for stability maintainable so as to adjust to several conditions that are important for survival.
The way the body controls the body temperature in humans is a good description of homeostasis
Zippy Xylem. The xylem of a plant is the system of tubes and transport cells that circulates water and dissolved minerals.
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
