Explanation:

The average size of a grocery store chicken has more than doubled in the past century. The most likely reason for this change is that artificial selection created a larger breed of chicken.

Artificial selection, also known as selective breeding can be defined as the process of identifying desirable traits in living organisms such as animals and plants, and selectively taking steps to ensure that those phenotypic traits are perpetuated in the offsprings or future generations.

This ultimately implies that, farmers or breeders are saddled with the responsibility of choosing which plant or animal are selected for the production of favorable (special) offsprings.

Cesium.

Groups are the vertical columns that run up and down while periods are the horizontal rows. So to find the answer to this, go to the first column (Group 1) and find the sixth period (row 6) which will land you on Cesium, element 55.

Hope this helps!
