Find the modulus.
5. 3 + 4i
6. −2 − i
7. 7
8. 4i

Modulus of  : 3 + 4i = 5 , -2 -i =  , 7 =7 and 4i  = 4

Step-by-step explanation:

Let A = x+iy be a complex number.

Here, modulus of A  =

So here Similarly,

Modulus of   3 + 4i = = =   = 5

Modulus of   -2 - i = = =  

Modulus of  7 + 0i  = =  = 7

Modulus of   0 + 4i = = =  4

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.
