Bio 111-102 Homework #1‚ Lab 1 assignment My group examined the correlation between standing height and leg length in centimeters for ten of our classmates. Our supposition was that there would be a direct relationship and similarity between standing height in centimeters and leg length in centimeters. Therefore‚ our hypothesis was‚ if leg length increases‚ then standing height will also increase. 1) The steps for the scientific method are: • An observation is made • A question

Causes of recent declines in biodiversity The major causes of biodiversity decline are land use changes‚ pollution‚ changes in atmospheric CO2 concentrations‚ changes in the nitrogen cycle and acid rain‚ climate alterations‚ and the introduction of exotic species‚ all coincident to human population growth. For rainforests‚ the primary factor is land conversion. Climate will probably change least in tropical regions‚ and nitrogen problems are not as important because growth in rainforests is usually
