Answer:
C) It has a long preganglionic fibers
Explanation:
Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:
- somatic (voluntary) nervous system-controls the movements of the skeletal muscles
- autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
- sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
- parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
- enteric nervous system-controls the function of the gastrointestinal tract.
Answer:
A hematocrit value of your blood would be greater than normal because of dehydration.
Explanation:
The hematocrit value is an indicator of the proportion of the solid components of blood (red blood cells) with respect to the liquid component (it means plasma). When you are severely dehydrated, the proportion of plasma diminish while the solid components remain the same. In consequence, the red blood cells concentration will be greater and the hematocrit value (solid components/plasma) will be higher than normal. This condition is reversible, if you drink enough water, your hematrocrit values will be normal again.
The value sign(x) equals −1, 0, or 1 depending upon whether the value x is negative, zero, or positive. Sometimes this is written as sgn(x) as is the case h
El signo de valor (x) es igual a -1, 0 o 1, dependiendo de si el valor x es negativo, cero o positivo. A veces esto se escribe como sgn (x) como es el caso h
Answer:
Las células hijas de mitosis se denominan células diploides. Las células diploides tienen dos conjuntos completos de cromosomas. Puesto que las células hijas tienen copias exactas del ADN de la célula madre, no hay diversidad genética creado a través de la mitosis en las células sanas normales.
