Oil is being obtained from the Arctic region, and this can cause environmental problems when there are spills since normally toxins take much longer to be degraded in colder temperatures. There are two good possible strategies to help clean up oil spills in the Arctic using bioremediation. One idea would be evolving oil-eating microbes that are found in warmer temperatures like the Gulf of Mexico to live in the Arctic. Another would be to genetically engineer the petroleum-degrading genes into psychrophilic organisms. 1st attempt Part 1 (1 point)See Hint What kind of cellular changes would be expected in oil-eating microbes moved from a warmer environment to the Arctic? Choose one: A. increased cholesterol in the membranes and increased glycogen storage for nutrient availability B. increased cell wall thickness to act as a blanket against the cold and decreased movement to save energy for other important functions C. increased cellular movement to keep the temperature higher and increased pore production to allow ice crystals to be pumped out of the cell D. increased unsaturated fatty acids in membrane phospholipids and development of trehalose being used as a cryoprotectant

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
