Obesity and Biology Obesity isn’t classified as an eating problem anymore. It is more than that a person’s biology plays a big roll. Cells and hormones play a big roll on how big you are and how your body regulates energy. Food equals energy and the body stores that energy in fat cells and uses the energy as needed. The metabolism breaks down that food and uses the energy generated from that food for everyday activities such as walking‚ talking‚ thinking. The faster ones metabolism is the more efficient

Lesson 1 - Introduction to Biology and Scientific Investigation The study of the living world. Modern biology encompasses all levels of organization and interaction: • among organic molecules • among organelles within a cell • among cells in an organ • among the organ systems in an organism • between organisms and the abiotic environment • among individuals in a population • among species in a biological community Knowing the facts of biology without an understanding of the relationships

When referring to the graph and data table of the class average‚ everyone’s data remained relatively the same‚ with the exception of the sugar Lactose‚ which had a drastically lower ppm/min for each group. This sugar basically did nothing during the lab experiment‚ while glucose‚ sucrose‚ and fructose (when used) produced the higher amounts of carbon dioxide. Even though not all groups experimented with sucrose‚ fructose‚ or lactose/lactaid‚ the five respiration rates (excluding lactose) ended up with

Basic Biology Genetic diversity describes the genetic differences seen among members of a population. What this means that that every individual on the planet is different from one another in some way. This is because we have either high genetic diversity‚ or a low genetic diversity‚ which is seen through the size of the gene pool from which we came. If we happen to live in a gene pool that has a high concentration of genetic diversity‚ then we are more like to have many different genetic combinations

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic
