Answer:
Shark is hyperosmotic relative to sea water.
Explanation:
The sharks that live in the marine environment do not need to drink sea water unlike others.
This is because the concentration of the urea and oxide is trimethyl amine gets deposited in the tissues of the shark which is hyper osmotic condition to the outside environment( sea water).
There is an adequate amount of potassium, sodium and chloride in the body of shark.
This is how the shark maintains the osmoregulatory mechanism in marine environment.
A. they prevent soil erosion
because they cover the soil (thus the name) to keep wind or water from washing away the soil.
Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of <em>Staphlococcus</em> <em>aureus</em>.
Explanation: The methicillin resistant <u>Staphlococcus</u> <u>aureus</u> is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;
In a strain of <u>Staphlococcus</u> <u>aureus</u>, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.
This is why the rate of methicillin-resistant <em>Staphlococcus aureus</em> has increased along the years.
