Choose True or False for each statement. You can compare irrational numbers using rational approximation. Square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol. You cannot compare the value of rational and irrational numbers. The closer together the numbers being compared, the more decimal places you need to use.

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.  

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
