Morillo MA SciEd Specialization in Chemistry Environmental Chemistry 08 December 2012 HOME A film by Yann Arthus-Bertrand Short version: 92’ 2009, France, digital Film company: Elzevir Films – EuropaCorp Distributor in France: EuropaCorp Distribution SYNOPSIS The appearance of life on Earth was the result of a balance between elements that took billions of years to stabilize. Humans have profited from the lavish resources of the Earth, but have changed the face of the world

What is Microbiology? Microbiology is the study of organisms too small to be seen with the naked eye. Originally, emphasis was placed on harmful micro organisms which cause disease or spoilage of beverages and food, but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur, such tuberculosis

of myoblast (the cells). Myofibers are multinucleated cells made up from the thin filaments called actin and thick filaments myosin myofibrils (long protein bundles) which are repeated as sarcomere, which act as the machinery for muscle contraction and gives it the striated appearance. Cardiac Muscle Smooth Muscle Skeletal Muscle The eukaryotic cell is composed of a numerous membrane bound organelles which work together to make a cell function based on

Nucleus is at the centre of the cell, it has coded instruction that enables it to make specific protein; this is how ribosomes are made here. This is bounded by a double membrane; the cytoplasm is like material within the nucleus this is called the nucleplasm (Rowland, as biology, 2008). The nucleus stores, replicates and decodes DNA. , which gives each cell it unique characteristics; this means liver cells are is different from muscle cell and is different from a fat cell. It is also the largest and

larger solid particles are taken into the cell by being surrounded by the plasma membrane and passing through. Endocytosis is when smaller more soluble particles are taken in by the plasma membrane forming a sort of hole and then the hole is pinched off containing the smaller particles turning into a vesicle which is taken where it needs to go. Question 5. A scientist might choose light-microscopy over electron microscopy because you can use living cells and watch how different factors affect them

Abstract Cloning first kick-started in 1996, with the cloning of Dolly, in which there was no male involved in the cloning. Ever since Dolly, hundreds of animals have been cloned. Every single day, scientists are getting close and closer to cloning humans. With the technology today, it is seems more evident to happen. Nevertheless, not everyone believes that we should be cloning humans. In the United States right now, there is no law banning any kind of human cloning. This means that at this

BIO 264 - Human Anatomy and Physiology Chapter 3 – Cell Biology and Genetics PART A 1. Describe the structure of a typical animal cell. Describe the structure and function of each of the cell parts labeled in Figure 3.1, plus cytosol, cytoplasmic inclusions, and flagella. * Plasma Membrane- Outer boundary of the cell, through which the cell interacts with its external environment. * Nucleus- It directs cell activities, most of which take place in the cytoplasm. * Flagellum- Extension

body structure units and their functions? The four basic human structures are cells, tissues, organs, and systems. The cell is the smallest building block of the body, and is the basic structural and functional unit of all known living organisms. They live independently and can reproduce itself. A group of cells form Tissues. They come in all different sizes such as elongated, square, oval and even star shaped. The cell is made up of protoplasm (jelly like substance), it is 70% water plus organic

Analogies a) Nucleus- The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. These two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). b) DNA- It is a molecule that stores genetic information required for the development of the body and the control of cellular processes
