Name_______________________Period___________ Chapter 6: A Tour of the Cell Concept 6.1 Biologists use microscopes and the tools of biochemistry to study cells 1. The study of cells has been limited by their small size‚ and so they were not seen and described until 1665‚ when Robert Hooke first looked at dead cells from an oak tree. His contemporary‚ Anton van Leeuwenhoek‚ crafted lenses and with the improvements in optical aids‚ a new world was opened. Magnification and resolving power limit

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

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

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic
