Mr. Fowler's science class grew two different varieties of plants as part of an experiment. When the plant samples
were fully grown, they compared their heights.
Plant variety Height of plant (inches) Mean Mean absolute
deviation (inches)
Variety A 20, 17, 19, 18, 21
19 1.2
Variety B 13, 18, 11, 9, 14
13 2.4
Based on these data, which statement is true?
A. The average height of variety A is greater and varies more than
that of variety B.
OB. The maximum height of variety B is greater than that of variety A.
C. The average height of variety A is greater but varies less than that
of variety B.
D. Variety A always grows taller than variety B.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
