A biology student estimates a population of snails in local field using randomly selected eighth 1.0m^2 quadrants in a 10m*10m site. the numbers of slugs in each quadrant were 3,9,4,2,3,7 5 and 1 A. Estimate the population density of slugs in this study site
B. Estimate the total population of slugs in this study site
C. What assumptions do you make when using the quadrat sampling technique? state at least 2. assumptions and explain why they are important.

Which statement about relative potential energy of electrons is correct? a. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 2 s orbital of the second electron shell. b. an electron in the 2 p orbital of the second electron shell has more potential energy than an electron in the 3 p orbital of the third electron shell. c. an electron in the 3 p orbital of the third electron shell has more potential energy than an electron in the 2 p orbital of the second electron shell.
