In this question, we are looking at metabolic rate in birds and amphibians.
00:09
We're told that birds have a higher weight -specific metabolic rate amphibians, and we're given the equation m equals a, w, b, which represents the relationship between metabolic rate and weight, with metabolic rate being m and weight being w.
00:33
We also have these constants a and b, and we want to know what is the most likely combination of values for the constants in this equation.
00:44
So we don't have any information about what the constants are or what they mean.
00:50
But doing some simple math, we can figure out the right answer here.
00:56
So we know that birds have a higher weight -specific metabolic rate.
01:02
That means that the constants that have a larger influence on weight on the second half of the equation, they will be higher in birds than in amphibians.
01:22
So we have two different constants here, a and b.
01:28
And we want to figure out which will have a larger effect on metabolic rate.
01:34
So we can do this by choosing a random number for weight.
01:40
So we'll see w equals, let's say, five grams.
01:49
And then if we plug in numbers for a and b, we can figure out which one has a bigger effect on m.
01:58
So if we say a equals three, and b equals three, just for the purposes of figuring out which one has the effect.
02:08
We can do the first part.
02:09
We can do three times five, which equals 15.
02:13
So this is that aw...
