b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally

Hypothesis 1: It was hypothesized that the growth and seed pod production in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and‚ on average‚ produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends

Melissa Morales Bios 101 Spring 2013 Demography- Human Life History Introduction Demography is the study of human populations. It studies the size‚ composition and distribution of a population‚ and the process through which a population changes. Demography allows us to track changes over time and to depict how different periods in history change population dynamics. Births‚ deaths‚ migration and emigration‚ jointly produced the change within a population (Biological Science). Demography

CELL REPRODUCTION DNA is the cell’s genetic material; chromosomes are the carriers of this genetic information. In proka-ryotes‚ the chromosome is a single circle of DNA. In eukaryotes‚ each chromosome is a complex of DNA and histone proteins found in the nucleus. BINARY FISSION Prokaryotic cells reproduce via binary fission. In this process‚ DNA Is replicated‚ and the cell splits in two roughly equal parts‚ each with a copy of the cell’s DNA. EUKARYOTIC CELL CYCLE Eukaryotic cells reproduce
