Below is a list of physiological events involved in modulating respiratory rate. Using your knowledge from class, place the events in the correct order. A. Medullary respiratory centers are stimulated.
B. CO2 levels in blood decline.
C. Somatic motor impulses are sent to the respiratory muscles.
D. Diaphragm and external intercostals contract at a faster rate.
E. More CO2 is exhaled.
F. Extracellular fluid surrounding brain decreases in pH.
G. PCO2 increases in blood H. CO2 produces H by reacting with water.
I. Central chemoreceptors are stimulated.
J. pH of brain extracellular fluid returns to normal.

The events in the order are,

G. PCO2 increases in blood.

H. CO2 produces H+ by reacting with water.

F. Extracellular fluid surrounding brain decreases in pH.

I. Central chemorEceptors are stimulated.

A. Medullary respiratory centers are stimulated.

C. Somatic motor impulses are senT to respiratory muscles.

D. diaphragm and external intercostal muscles contract at a faster rate.

E. More CO2 is exhaled.

B. CO2 levels in blood decline.

j. pH of brain extracellular fluid returns to normal.

Explanation:

In physiological events that take place in modulating respiratory rate is a compensatory mechanism occurs in the case of respiratory acidosis. In respiratory acidosis, carbon dioxide level increases in blood so the partial pressure of carbon dioxide will be higher.

The high amount of carbon dioxide is responsible for the formation of the bicarbonate and hydrogen ion this process continues, which decreases the normal pH. Chemoreceptors sense this change that activates the respiratory centers. and sends motor signals for the contraction of inspiratory muscles, which increases the rate of respiration.

The correct order of events in listed above.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
