The scale factor of an object is the ratio of the lengths of two corresponding sides of two similar objects. True

False

True

Step-by-step explanation:

If there are 2 similar geometric figure the ratio of the corresponding side length is regarded as the scale factor. For example if you have 2 similar  figure like a  square. And you detect 2 corresponding sides of the figures , one having a length of 2 cm and the other a length of 4 cm. The ratio of this 2 corresponding side is the scale factor . The scale factor can be express as 1:2. or the scale factor can be represented as a fraction as 1/2.

In a more simple term the scale factor is the ratio of 2 corresponding side of similar figures. Note the figures must be similar . The scale factor can be use to find the side length of a figure and also one can use the side length of the figures to find the scale factor.

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.
