Antihistamines are drugs that are used to treat allergic rhinitis (both seasonal and perennial) and other form of allergies that cause hives or urticaria. They can give relief when a patient has nasal congestion, sneezing or hives because of pollen, dust, or animal allergy (allergens). Second generation antihistamines such as loratidine are prescribed for seasonal allergies because they are less sedating than the first generation antihistamines.
Answer:
It is because sedimentation will more often occur in marine ecosystems
Explanation:
Formation of fossils (through the process of fossilization) is a rare event because animal bodies are often eaten and decayed (destroyed by scavengers and decomposed by worms). But, fossilization can be achieved after the quick burial of an animal.
So, for example, dead marine animals might be buried by sediment that is carried by the water. Also, sediment can precipitate on the ocean floor, covering the remaining of dead animals.
The liver is your largest internal organ. About the size of a football, it's located mainly in the upper right portion of your abdomen — beneath the diaphragm and above your stomach — but a small portion extends into the upper left quadrant.
Answer: Life would cease to exist.
Explanation:
The carbon elements is one of the most important elements in the compound that make up living organisms. It is found: in the remains of living organisms; as fossil fuels such as coal, coke and natural gas; as inorganic salts such as carbonates; in water bodies and as gas carbondioxide which makes up 0.03% of air.
Carbon is continuously being circulated in the atmosphere through a process called the CARBON CYCLE. This involves the removal and addition of carbon to the carbondioxide in the atmosphere.
Life would indeed cease to exist if this carbon cycle stops due to the importance of carbon to functioning of living organisms. Important processes which bring about the recycling of carbon between living ( biotic) and non living (abiotic) components of an ecosystem are:
--> photosynthesis: the process used by green plants to remove carbon through carbondioxide from the atmosphere for manufacturing of their food.
--> respiration: animals respire to break down sugar leading to liberation of carbondioxide and water as wastes
--> and decay: decomposers feeds on remains and waste to bring about decay, thus complex carbon compounds are broken down to set free carbondioxide which returns to the atmosphere.
All the above processes are carried out by living organisms to maintain a functioning ecosystem by enabling a linear flow of energy through it.
