Escreva, em forma de fração, uma razão em que:

a) o antecedente é 3 e o consequente é 10

b) o antecedente é 15 e o consequente é 11

(a)

(b)

Step-by-step explanation:

" The ratio a:b can be represented as a by b i.e.   a/b. Here, a is called the antecedent and b is called the consequent "

(a)

The antecedent is 3 and the consequent is 10.

i.e. a=3 and b=10.

Hence, the ratio or fraction could be written as:

Hence  is the required ratio.

(b)

The antecedent is 15 and the consequent is 11.

i.e. a=15 and b=11.

Hence the ratio or fraction could be written as:

Hence, the required fraction is:

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.
