Part 1: human population growth
year
1. the data table below shows the changes in the human population over time. on the grid below, label and
scale each axis. then, plot the points from the data table below. connect the points with a smooth line.
use your completed graph and the data table to answer the questions on the next page.

Draw the structure of dna nucleotide with adenine as nitrogenous base

The human genome project is devoted to mapping the general dna sequence of our species. this could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases. however, there are some ethical issues surrounding the mapping of individual genomes. one concern is a) that your genes may change over time, making the project useless. b) that insurance companies could discriminate based on genetic make-up. c) that since this has never been done before, we should probably not do it now. d) that sequencing our individual genomes is so expensive, it is a counter-productive strategy.

Drag each label to the correct location in the equation. not all tiles will be used. the density of mercury is 13.6 grams per cubic centimeter. complete the steps for converting 13.6 g/cm3 to kg/m3. (1 kg = 1,000 g, 1 m3 = 106 cm3)
