Haloarchaea often have genomes with high GC content because Choose one: A. GC base pairs help keep the DNA helix intact in the high-salt environments where haloarchaea are found. B. GC base pairs are more stable in the high-temperature environments where haloarchaea are found. C. more GC bases lead to more acidic proteins. D. GC base pairs are less stable than AT base pairs and allow for easier DNA unwinding for replication.

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
