and sister chromatids? Homologous chromosomes have the same arrangement of genes but are not connected to each other. Sister chromatids are identical: the result of DNA replication. The two connected chromatids are considered to be one chromosome. 3) What are tumor suppressor genes (11.18-11.19) and what is their role in the cell cycle? Tumor suppressor genes are genes that regulate the growth of cells. When functioning properly‚ these genes can stop the growth of tumors. They can communicate to

AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment

The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

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
