Ventilation is the process which the air moves in and out of the lungs. Diffusion is the movement of gases without the use of energy and or effort by the body. Hope this helps!:)
In mid-ocean ridge areas, ocean water is cycled through the crust because of the high heat flow in the area. Water in the rock is heated over the magmas, rising up and drawing in cold water from the sides. This process is occurring all over the world, and is the primary means for maintaining ocean salinity in a relatively constant range over the long term, as elements in the sea water when it is heated react with the rocks. There is so much water flow, cumulatively over the entire world, that this process basically buffers ocean chemistry.
Obviously large increases or decreases in salinity can and do occur in isolated basins that do not have free exchange with the open oceans.
Answer:
<em>The correct option is C) AS</em>
Explanation:
Sickle cell anaemia is a recessive disorder in which the blood of the person is not able to clot properly. For sickle cell to occur, both the alleles for the trait have to be recessive. A person who has a dominant and a recessive allele will be heterozygous, showing the dominant characteristics. But such a person will be a carrier for the disease. There will be chances for the offsprings of that person to actually have the disease.
Given what we know, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
<h3>What happens when a person's hand is near a flame?</h3>
We can say that the information from the heat being generated by the flame is received by sensory neurons in the person's hand. This information generates a pain response which is integrated as incoming information in the brain, which then produces a motor response to move the hand away from the flame, as an outgoing signal.
Therefore, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
