Answer:
c) "Oxygen therapy has been shown to help relieve cluster headaches."
Explanation:
Cluster headache is a type of headache that involves a series of pain in the face that stems from one part of the eye and could spread across to the forehead d other parts of your head. This pain which comes suddenly is often short lasting between 30 to 80 minutes that could reoccur almost at the same spot and at the same period of time the person usually witnessed it. The trigeminal nerve, which is close to the eyes, is said to be affected during this attack.
This type of headache is usually difficult to treat due to its nature, as there seems to be no known cure for it. However, there are several treatments that have been employed to reduce the intensity this headache and also preventing it.
Oxygen therapy is an effective therapy that has been shown to relieve this type of headache. It involves the inhaling of pure oxygen with the aid of a mask. This method brings relief within few minutes during the attack
.
1. It peaks in spring and decreases in fall.
2. Absorbs and re-emits infrared radiation
5. The health of coral colonies
Explanation:
(1)
This is caused by the formation of Polar Stratospheric Clouds (PSCs) during winter in the polar regions. These clouds offer a surface area on which the CFC chemical reaction occurs at a fast rate causing ozone depletion in the polar stratosphere by as much as 50%. This peaks at spring when the temperature begins to warm-up providing an increase chemical reaction rate of the surfaces of these clouds.
(2)
These greenhouse gases, therefore, prevent the escape of infrared radiation from the earth surface towards space. The absorption and re-emission of the radiation caused this radiation to be trapped in the atmosphere. Remember that infrared is the electromagnetic ration spectrum responsible for transferring heat energy. This is why the atmosphere warms up with an increase in greenhouse gases in the atmosphere.
(3)
The good kind of ozone is the one that is high p in the atmosphere in the stratosphere. It is significant because it prevents UV rays from reaching the earth’s surface which may be harmful to live organisms. The bad ozone is the one that forms in the lower atmosphere close to the earth’s surface because it is harmful when breathed in and also destroys vegetation. It is therefore a pollutant. Ozone is in large concentration near the tropic and lowest in the poles.
(4)
An increase in greenhouse gases is causing climate change. A significant phenomenon as a result is the enhanced melting of polar ice sheets and the increase in ocean surface levels. This results in the displacement of coastal communities as a result. Their migration may cause conflict due to competition for resources in the region they migrate to.
(5)
Coral is very sensitive to changes in ocean properties. This is why climate change is causing massive bleaching of coral around the world. This is because climate change has caused an increase in oceans' temperatures and pH. pH is a result of the increased capacity of dissolved carbon dioxide in the oceans. Increased formation of carbonic acid has caused a lowering of ocean pH.
(6)
Breaking of the Montreal protocol by signatory countries would cause an increase in emissions of CFCs into the atmosphere. This would result in an increased rate of depletion of the ozone. More UV rays would reach the earth's surface and affect living organisms on the earth’s surface. This is because destroys genetic materials by causing double-stranded breaks. This creates a recipe for increased rates of cancers.
<span>Darwin believed the shape of the finch's beak was related to the food it ate.
This is pretty simple obviously the first three wouldn't be the answer. </span>
The genotype of an octopus is DD or Dd if an octopus of this species has long arms. DD genotype gene is defined as a linkage marker for an etiologic mutation at or neat the angiotensin-converting enzyme gene and has been associated with increased risk for the development of coronary artery disease. The genotype is DD or Dd.
Answer:
diploid
Explanation:
diploid cells have 23 chromosome pairs, but egg/sperm cells are haploid and don't chromosome pairs
