The leaf beetle, Chrysomela aeneicollis, lives in the Sierra Nevada Mountains of California. Scientists studying the beetles found that exposure

to high temperatures during the summer, when the eggs are laid and the

larvae are developing, causes physiological stress. The impact is on

metabolic enzymes and heat shock protein expression. One allele, pgi-4,

increased in frequency in the beetle population that was exposed to hotter,

drier summers in the Sierra Nevada Mountains.

If the temperature in the Sierra Nevada Mountains continues to increase,

what will happen to the frequency of the pgi-4 allele?

A. Increase

B. Decrease

C. Stay the same

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.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
