Answer:
A dermatome represents the unilateral area of skin on the body that is innervated by fibers from the sensory portion of a single spinal nerve coming from the spinal cord. Each spinal nerve contains spinal roots (anterior and posterior) that come together to form the spinal nerve.
Explanation:
Answer:
In cotransport, a single ATP-powered pump that transports a specific solute drives the active transport of several other solutes. Normally, sodium in waste is reabsorbed in the colon, maintaining constant levels in the body, but diarrhea expels waste so rapidly that re-absorption is not possible, and sodium levels fall precipitously. To treat this life threatening condition, patients are given a solution to drink containing high concentrations of salt and glucose. The solutes are taken up by sodium-glucose cotransporters on the surface of intestinal cells and passed through the cells into the blood. This simple treatment has lowered infant mortality worldwide.
I would say that the answer is D.
A warm fronts move from the south to the north
<u>Explanation</u>:
A warm front are formed when a warm mass of air is pushed into a cold air mass. Since the warm air mass at surface rises above the cold mass of air they often causes stormy weathers. Also due the difficulty of warm air in pushing the cold dense air across the surface of the earth make the warm fronts to move slower when compared to cold fronts. Unstable air produces thunderstorms around the warm fronts. solid red line with red, filled-in semicircles is used to represent a warm front on the map.
Answer:
Option (1), (2) and (3).
Explanation:
Doppler effect may be defined as the change in wavelength due to the the movement of sound or radiowaves travels from the object. The frequency remains same if the distance between the receiver and sender's electromagnetic wave distance is same.
Doppler effect helps to learn about the universe behavior. Hubble used the Doppler effect to study the velocity of galaxy. The galaxy motion can be indicated by the wavelength and light.
Thus, the correct answer is option (1), (2) and (3).
