group Caminalcules species in your taxonomic classification (chart)? What does this suggest about classification based on strictly of similarity versus evolutionary relationship? The phylogenetic tree was more of an evolutionary tree. It showed the evolution of the organisms and their ancestors or traits that they branched off of. The chart however just simply organizes and separates the organisms in similarity. The tree did not change the chart‚ the chart see similarities with structures between the

Question 1 What are probable sources of acid precipitation in your community? What impact can this have on the environment in your region? Some of the probable sources of acid precipitation is Fog‚ and rain. During the summer it hardly rains which makes it hard for our crops to grow‚ also since we are in the valley it makes it hard for us to get the water that we need. During the fall it gets very foggy in the mornings and it makes it very difficult to see while your driving. Prevailing
