Answer: Abiotic factor for polar: Ice
Abiotic for desert: Sand
Biotic for polar: Polar bears
Biotic for desert: Cacti
The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.
Explanation:
Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense (i.e. warmer) and rises. The cooler air from the land moves in to take its place. Sea breeze: Sea breeze blows during the day and the land heats up faster than the sea
First pass metabolism of a drug is said to occur when the concentration of a drug that is administered orally is significantly reduced before it reaches the systemic circulation.
First pass metabolism usually occur in the liver.
The routes of drug administration that avoid complete first pass metabolism are: sublingual, transdermal, rectal and inhalation.
If a flood occurs in the natural rubber environment, it will ruin the rubber production process. The flood would damage a huge percentage of rubber trees if there was a large quantity of restriction. This natural rubber is required for the production of synthetic polymers. Without the rubber, there would be a restricted supply and a significant decline in synthetic polymers due to ecological damage caused by the flood.
Anything that says further apart is incorrect. So B is incorrect.
A is correct as near as I can tell.
C is not correct. The particles. I think C is the right answer supplied with the wrong reason. Regretfully, you can't choose it.
Same answer as C for D. Right answer wrong reason.
Answer A.
