Mitosis and meiosis are both important biological processes that happen within eukaryotic cells. These two processes are slightly different from one another‚ but have a lot of similarities. Before each of these processes can be performed‚ the cell first has to go through interphase. Interphase is considered the primer for mitosis or meiosis and consists of: G1‚ S‚ and G2 phases. These phases prepare the cell for either mitosis or meiosis by causing the cell to grow‚ copy the DNA‚ and copy the cell’s

Understanding the Principles and Practices of Assessment Q1 - Explain the Function of assessment in learning and development The assessment cycle continues until all aspects of the qualification have been achieved by the learner:- Initial assessment – Prior knowledge of the subject to determine teaching style. Assessment planning – agree what types and methods of assessments are to take place Assessment Activity – what methods‚ e.g. observational/ assignments/ questioning Assessment decisions

and during this process they begin to specialize. A rabbit‚ an elephant‚ an oak‚ or a human being finally develops from a single cell. There are two main types of cell division: (1) mitosis and (2) meiosis. (Balls 34) Most cells are produced by a process called mitosis. In mitosis‚ a cell divides and forms two identical daughter cells. (Prescott 102) Each daughter cell then doubles in size and becomes capable of dividing. Most one-celled plants and animals reproduce by mitosis. (Baserga Biology

There are two processes of cell division that are very tricky. They are mitosis and meiosis. Many people often get confused with the two about their functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while

Sexually Transmitted Diseases (STDs) The Basics Sexually transmitted diseases (STDs)‚ also called sexually transmitted infections (STIs)‚ are diseases and infections that are passed from person to person through sexual contact. HIV is an STD. There are more than 25 other STDs that are mainly spread by sexual contact such as vaginal‚ anal‚ and oral sex. The US has the highest rate of STDs in the developed world. In the US‚ about 19 million new infections occur each year. Teenage girls and young

Mitosis in Plant and Animal Cells OBJECTIVES Observe and identify cells undergoing the process of mitosis. Compare the stages of mitosis in plant cells with these stages in animal cells. MATERIALS • compound light microscope • prepared slides (longitudinal sections of onion or garlic root tips) • prepared slides (whitefish blastula or other animal tissue) Procedure PART 1: MITOSIS IN PLANT CELLS 1. Observe a prepared slide of a longitudinal section of onion or garlic root tips. Use low

STDs (Sexually Transmitted Diseases) are diseases that are transmitted through sexual intercourse with another domestic partner. Usually STD’s are transmitted through oral‚ anal‚ vaginal‚ or other sexually active bodily contact. Sexually Transmitted Diseases are 100% avoidable. There are many techniques‚ but the most effective way is to have sexual intercourse with only one partner in your whole life‚ making sure that your partner didn’t have sexual involvements with anyone else. Another method is

Counseling is: • The process that occurs when a client and counselor set aside time in order to explore difficulties which may include the stressful or emotional feelings of the client. • The act of helping the client to see things more clearly‚ possibly from a different view-point. This can enable the client to focus on feelings‚ experiences or behavior‚ with a goal to facilitating positive change. • A relationship of trust. Confidentiality is paramount to successful counseling. Professional

Meiosis Modeling Activity Background Information Meiosis is the process by which eukaryotic organisms produce egg and sperm having half the genetic information (haploid) of the other cells in the organism’s body (diploid). You will notice some similarities to mitosis but some definite differences in meiosis that result in genetic diversity in the gametes as well as the offspring formed by the eventual fusion of the egg and sperm. Two of the most noted differences in meiosis are that 1) there
