Answer:
Under normal circumstances, bronchoconstriction is caused by Parasympathetic nervous system and bronchodilation is caused by sympathetic nervous system
Explanation:
bronchoconstriction is simply a a tightening, narrowing or constriction of the of brochioles ( airlways) that increase in mucous secretion and it may occour due to coughing, sneezing or any other factors.while bronchodilaiton is the relaxation or the dilation of the bronchioles (airways in the lungs) that decrease of mucous secretion
An increase in parasympathetic activity causes BRONCHOCONSTRICTION, a decrease in parasympathetic activity causes BRONCHODILATION. There is no sympathetic innervation of the bronchiole smooth muscle!
The effect of the Smooth muscle contraction usually may cause bronchoconstriction to decline or decrease in the diameter of the bronchioles while the effect or the result of the smooth muscle relaxation may cause bronchodilation to increase in the diameter of the bronchioles. Therefore, Parasympathetic stimulation leads to bronchoconstriction and sympathetic stimulation leads to bronchodilation.
Answer:Mixed factorial design
Explanation:
Mixed factorial design is a design that involve the use of two or more independent variable where one of the independent variable is between group and the other is within subject independent variable.
Temperature is the independent variable between the group and noise is the independent variable that is exposed to within the subject.
It is mixed because it has many factors relating together.
C. to convey a certain tone.
Primates usually have five digits on each limb, with a fibrous protein forming the main structural constituent of nails on the end of each finger and toe. They have sensitive pads on the fingertips on the bottom sides of the hands and feet. Most primates can move toward and touch the other digits on the same thumbs, flat, and short fingernails.
