Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question what is the effect of the type of food available on the frequency of different types of bird brakes hypothesis is a type of food available change then because

The correct answer would be -

If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.

Explanation:

According to the theory of natural selection, an organism that is able to adapt according to the change in the environment, it helps in their survival and increases their number in the system.

It is given that the type of food available is changing, so it will lead to the change in the frequency of bird beaks in that particular area. So, if they adapt to survive under the changes in the available food type, otherwise not be able to survive and die.

So,

If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.

b.have there own function.

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.
