Question 29 of 31 3.0 Points As mentioned in the lab, in addition to poaching, why have elephant populations been decreasing over the last few years? A. Food Shortage B. Habitat Loss C.

Water Issues Feedback: Review Lab 1: Scientific Method Part 6 of 7 - Lab Essay 5.0 Points Question 30 of 31 5.0 Points In a few sentences, what was the overall purpose of the lab for this week? You should include 1-2 sentences on the methods and then the overall reason. The purpose for the lab was to better understanding the extension of the elephants. We also learned the process for the surveys and study of the population. Having to learn about the process and studies that are perform helped me understand how it was possible for Scientifics to understand the life of the elephants. They can learn the process and how they move from one place to other by using multiple equipment. Comment: The purpose of the lab this week was to explore the scientific method and how science is conducted through observation studies. The decline of African elephant populations were used as the example.Part 7 of 7 - Lab Upload 8.0 Points Question 31 of 31 8.0 Points Please upload your completed Lab Packet for this week.
