Purpose: In this lab, six different types of soil were created, ranging from 5% NaCl to H2O. This was done to test if blue flax seeds have the ability to germinate and grow in soil consisting of salt, as salt in soil has been shown to be a problem in agriculture.
Results: The results showed that blue flax seeds do not have the ability to grow in soil which contains any percentage of salt. The blue flax seeds only grew in 100% H2O, with only two of the six seeds in the soil growing, and the seeds germinated once they were in sunlight, rather than being without sunlight.
The population in Cambridge, Massachusetts is declining. However, there is a large amount of that could have children and change the birth rate.
Philadelphia, Pennsylvania has a generally stable population. The amount of children being born is close to the amount of adults.
Half Moon Bay, California has a population that is slightly declining. The number of children is close to the number of people in the reproductive ages, but not enough to replace them.
Manhattan, New York has a declining population. The decline in population probably has to with the large amount of adults that are focusing on their careers, rather than on creating a family.
New Haven, Connecticut has a population that is relatively stable. Beside the post-reproductive age groups, most of the age groups have relatively the same mount of people.
Portland, Oregon has a shrinking population. There is not enough children being born to replace their parents so the population is declining.
