In this field of sunflowers, variation exists. some flowers are tall, others short, and finally some plants are an intermediate height. the tallest plants shade the shorter; the taller plants are pollinated first. over time, we might expect this field of sunflowers to be mostly tall. according to this scenario, we would classify the production of the sunflowers in what area of this venn diagram? a) b) c) d)

Option A

Explanation:

As given in the question, the flower plants of varied height characteristics are used.  

The characteristics of a plant being tall, short and intermediate is due to its genetic structure.  

Also, it is given that trait of being tall is dominant over other characteristics and thus with time only tall species will be there. This represents variation in the characteristics of offspring governed by natural crossing and selection. Sexual reproduction causes these variations and thus involve crossover of characteristics of both the mating species.

In asexual reproduction, look alike offspring are produced

Hence, it lies in the part A of the venn diagram

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
