Mature cells carry out different functions, like different medical specialists are experts in their field, like a cardiologist in the heart, the neurologist in the brain, etc. They undergo specialization to carry out their functions more efficiently. Organisation is in this form: †¢ †¢ †¢ †¢ Cells that carry out a function are grouped into tissues. Different tissues that carry out a function are grouped into an organ.

While students have the option of picking from a B.A. or a B.S., the focus of a B.S. in biology has more scientific purposes. Graduation requirements are difficult, but certainly not impossible, requiring 67-68 credits over 4 years. These credits include 36 biology credits, 16 chemistry credits, 8 math credits and 8 physics credits. The job opportunities that becomeRead MoreExploring Biology854 Words   |  4 PagesAP Biology Reading Guide Chapter 1: Introduction: Themes in the Study of Life Fred and Theresa Holtzclaw Name_______________________Period___________ Chapter 1: Introduction: Themes in the Study of Life Begin your study of biology this year by reading Chapter 1. It will serve as a reminder about biological concepts that you may have learned in an earlier course and give you an overview of what you will study this year. 1.

The experiments were based on form 5 and form 4 practical books. The science fair was conducted by teachers from science department and was divided into three different subjects; physics, chemistry and biology. The objectives of the science fair are; 1. One of the programme during the activity week. 2. As a teaching platform to introduce physics, chemistry, and biology subject to lower secondary and for further understanding in the science subjectsRead MoreWhat Color Bead Bug?1042 Words   |  5 Pageswhich organisms have changed over time† (Biology 450). Charles Darwin is responsible for discovering the the theory of evolution (Biology 450). Darwin was a naturalist and a scientist. He created the theory of evolution, by sailing around the world on The Beagle (Biology 451). While sailing, he filled a notebook with observations and discoveries of the different habitats and environments (Biology 451). His studies of organisms around the world led him to form his theory of evolution and his views onRead MoreTest 12 Different Aqueous Solutions Containing Macromolecules1062 Words   |  5 Pagesthis creates a tight helix and this turns the solution black/ dark blue.(Ophardt, 2003) The way Glycogen is identified is when the solution turns reddish-brown. Glycogen is very sim ilar to amylopectin as it is made up of alpha glucose units joined at 1-4 and 1-6 and it is a branched structure. (Toole, 2004) Iodine affects glycogen similarly as it does amylose. The second test that is being preformed is the Benedict’s test, this test if for reducing sugars in the solutions.

Photosynthesis is represented by the chemical equation, 6CO2 + 6H2O + light → C6H12O6 + 6O2. The equation shows that carbon dioxide, water, and light react to form glucose (a carbohydrate) and oxygen. Each year, photosynthesis is responsible for ten percent of the atmospheric carbon dioxide on earth being reduced to form glucose (Whitmarsh and Govindjee). Photosynthesis is essential for the life of the cell because it provides energy for the cell to do all of its biological needs. PhotosynthesisRead MoreIntroduction to Prokaryotes Lab Report1283 Words   |  6 PagesIntroduction to Prokaryotes in Different Temperature Environments Angelina Orozco Biology 1108 Wednesday 7:30 am Abstract Prokaryotes are single-celled organisms that can survive in extreme environments. Bacteria is the more numerous type of prokaryotes. The group hypothesizes that the samples taken from different environments will all cultivate diverse morphology in fast growing rates in each environment. The aseptic technique was used to cultivate bacteria from different environments.

The body continually produced new cells by splitting from the ones that has already existed. Meiosis: can be defined as a particular form of cell splitting that generates reproductive cells, such as sperm and egg cells, plant and fungal spores. Steps involves in Mitosis Mitosis consists of four basic phases and they include prophase, metaphase, anaphase, and telophase.
