According to charles darwin's theories, how are natural selection and evolution related?
evolution is one mechanism by which natural selection occurs
natural selection is one mechanism by which evolution occurs
natural selection and evolution are synonyms
natural selection and evolution are antonyms

B

Explanation: I think the answer is B because natural selection leads to evolution because they happen in a line or like a chain reaction.

natural selection is one mechanism by which evolution occurs

Explanation:

One of the driving mechanisms for evolution to occur is Natural selection. it is how  nature used selection pressure( environmental factors) in the surrounding environments of the organism to select or favour the fittest organisms, against the less fitted, with increases  gene flow, and therefore   population as the fitted organisms, with subsequent increase in the offspring population.

Natural selection is driven by mutation which causes variation. These interrelated  forces   altered the Genotypes of fitted organisms, and therefore made them to have selected advantages over the less fitted ones.With period of time the population of the less fitted fizzled out, while the  fitted organism population  evolved to dominate the environments.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.

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.
