Biology 101 Internet Worksheet Number 4 Biology 101 (Instructor: Jim Gilardi) Directions: Answer the following questions in the space provided. I have tried to provide you with more than enough space. If you need more space, however, you may attach additional sheets, but make sure they are clearly marked. Answers must be neatly handwritten. Answers should be in your own words. Do not copy from the book, my lecture outline, or other students. You may want to review the section on cheating in the syllabus. Keep in mind that you have complete control over the quality of these answers. Be thorough and to the point. This worksheet is due when you take Exam 4. 1. Consider the following hypothetical population and compute the statistical measures below: #births 50,000; #deaths- 10,000; #immigrants 5,000; lemigrants 20,000; mid-year population 1,000,000. Show formulas and all relevant work. (12pts) BR= DR = APGR DT= Adjusted (True) Growth Rate = Adjusted (True) Doubling Time= 22

Answer 1

Caude birth rate Number of love birth thousan people ina Population. 10000 = 10 DR Birth rate a total no. of birth total population X 1000 50000 1000000 8000 50 BR Death rate = total no. of birth X 1000 total population 1000000X1000 Annual percentage goowth rate → & final value - Start value 2100 Start value final value = Population +(Birth red one 8 immigration) - Creath, cado $ emigration) 1000000 +(50000 +5000 ) - (10000 + 20000) = 1055000 - 30000 A 1025000 formalla – 1025000 – 1000000 LX100 525 1000 000 » 205 % APGR Doubling time →DT 70 500 TO growth rate 205 tormula -

Adjusted growth rate and Adjusted doubling time was not solved because proper idea is not given about that in question.
