Malik solved the equation 2x – 3(2x – 9) = 4 – (3x – 11) using the steps shown below.

Step-by-step explanation:

Given Equations are -

It is required to solve the given equations in four steps only.

Step 1 - solve the brackets first

step 2 - put all variable values on one side and constant values on other side

step 3- Do the addition and subtraction on LHS and RHS of the equation

step 4- removing the minus sign on both sides

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.  

the answer is a if my teacher taught me correct
