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

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses. cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown. cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan. cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan. select the correct statements regarding the mode of inheritance of the coat color genes. a) both genes are x-linked. b) both genes are autosomal. c) one of the genes modifies the expression of the other gene. d) each gene has an additive effect on the intensity of coat color. e) each gene independently specifies three colors. f) one of the genes is autosomal, and the other is x-linked.

Ascientific idea becomes valid when it is what?

In general, did the simulated mice align with your predictions from the punnett squares? yes or no?
