body structure units and their functions are: Cells, Tissues, Organs, and Systems. Cells Humans and all living things are made up of about 100 trillion small cells that can only be seen via a microscope. Cells can reproduce themselves and live independently. Some cells are specialized and become a different shape and size (elongated, oval, square, flat etc) dependant on its function. Here are just a few examples: * Epithelial cells – can be flat, cubed or column shaped. They protect

(see fig 1-2) Each level has ingredients or components which interact to make something greater than the sum of the parts. -Subatomic particles -Atoms -Molecules -Organelles (not present in prokaryotes) -Cells -Tissues (present only in multicellular eukaryotes) -Organs (present only in multicellular eukaryotes) -Organ systems (present only in multicellular eukaryotes) -Multicelled organisms -Populations -Community -Ecosystem -Biosphere Response

and can sometimes be toxic to the users. This is due to the differences between different people and the fact that everyone has a different genetic makeup. For example, Her2/neu genes code for a protein receptor, the Her2 receptor, which deals with cell growth and differentiation. Some polymorphisms in the Her2/neu genes can change how some women’s breasts grow, leading to possible tumors. Cancer can also cause mutations, making the Her2/neu genes overactive, leading to tumors. Thus, women with

Campbell's Biology, 9e (Reece et al.) Chapter 6 A Tour of the Cell This chapter introduces the topics of microscopy and cell fractionation, followed by a review of the cell and the major organelles and structures of eukaryotic cells. A challenge with this chapter is to keep this data from simply being a list of parts. In addition to the structure and function of individual organelles, questions probe student understanding of the cell as a dynamic, interconnected system: the flow of membrane and

today. It can be defined as the act of creating a new individual (reproductive) or organism (therapeutic) from the single cell of a parent subject. In reproductive cloning (human cloning) a parent subject is expected to act as a surrogate mother. Making the clone involves using the parent’s empty egg (nucleus and genetic code removed) combined with the nucleus of their own skin cells to create 1 embryo which is now a copy of them. Each time a procedure is formed a life hangs in the balance. This life

Selection * Some type of selective force * Have to have an explosive of population to occur Selection continues * It could be that human beings screwed with something the first time. * It could be some type of adaptation. * Artificial selection: You start of with artificial selection where nature is not doing it. It is us choosing which one to pick. So how does selection play a role in evolution? * Evolution: when changing or developing different characteristics over time

3.1 1. What is a cell? A cell is the smallest unit of life. 2. How have microscopes contributed to the study of cells? Microscopes have led to the discovery of cells, have allowed us to differentiate structures in prokaryotic and eukaryotic cells, have allowed us to study the organelles that make up a eukaryotic cell, and have even let us watch some basic cell functions as they occur. 3. What are the main components of cell theory? The main components of cell theory are that all

Booknotes Ch 6.3-7 Nucleus: Nucleus contains most genes in eukaryotic cells. Nuclear envelope- encloses nucleus, separating contents from cytoplasm *double membrane *perforated by pores Nuclear Lamina- netlike array of protein filaments. Mechanically supports nuclear envelope to keep its shape. Nuclear Matrix- framework of fibers extending through nucleus Chromosomes- carry genetic information. (DNA) Chromatin- material making up chromosomes. *DNA+Proteins Nucleolus- mass of density

Heredity Heredity is the transmission from one generation to the next of factors that determine the traits of offspring. Although successful breeding of plants and animals was practiced by humans long before modern civilizations were established, there is no evidence that these early people understood the nature of hereditary factors or how they are transmitted through reproduction. EARLY HISTORY One of the early Greek philosophers, Pythagoras (582-509 BC), postulated that all traits of
