Many factors lead to the beginning of the African exodus of the modern human population. The most prominent factors involved with their rapid expansion are the drastic climate changes in that area. As well as that‚ a diverse diet rich in seafood

Both naturalistic observations and cross-sectional studies are effective methods of research. In a naturalistic observation‚ the psychologist observes the subject without interfering. In a cross-sectional study‚ “data is collected from groups of participants of different ages and compared so that conclusions can be drawn about differences due to age.” They are similar in the way the data is obtained and they differ in the number of subjects and the usual age and maturity of the subjects.

Spontaneous generation theory was the thought that some forms of life could actually be spontaneously created out of thin air. An example of spontaneous generation was that flies could develop from manure for no reason other than just because that is how it was. Virchow knew this could not be true and delved deeper and is credited at defending the concept that living cells could only be created from previous cells was more accurate. This concept was later considered to be called the theory of biogenesis

Purpose: In this lab‚ we will heat up a metal rod and measure how much it expands. We will calculate its Coefficient of Linear Expansion‚ α‚ and prove the formula for thermal expansion‚ ΔL = αLiΔT. Also‚ we heat up a known volume of methyl alcohol and calculate its Coefficient of Volume Expansion‚ β‚ and prove the formula for volume expansion of a liquid ΔV = βViΔT. Equipment: Hollow Metal Rods of different metals‚ Steam Generator‚ Stand‚ Burner‚ Flexible Hoses‚ Motion Amplifier‚ Micrometer
