Theoretical Fluid Mechanics Module#1: 1 1. OBJECTIVE The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion. 2 2. DESCRIPTION The apparatus shown in Figure 1 will be used. It consists of a quarter circle block attached to a cantilevered arm with a rectangular surface on the other end. The pivot point on the arm corresponds to the center of radius of the block. With no water in the tank‚ and no weights on the

As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many plains and craters. The largest crater on Mercury is the Caloris Basin with a diameter of 1550km. Venus‚ the second planet from the Sun‚ is a solid and rocky terrestrial planet. Named by the

Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration to areas of lower

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

Presentation A. Entering the epithelia cell of the small intestine‚ until being loaded onto the proper tRNA. Amino acid present in the lumen of the small intestine The goal is to cross through the epithelial cell membrane to enter into the epithelial cell’s cytoplasm – its charged cuz of side chains To get through the membrane the amino acid must cross the Simple columnar epithelial cells lining the apical surface of the small intestinal tract. These cells are impermeable to any harmful bacteria

Activity 6.2-Membranes Organize a Cell’s Activity Dissect a Plasma Membrane Objective: to understand the structure of a membrane 1. Why is the membrane described as a phospholipid bilayer? It is described as a phospholipid bilayer because there are two layers of phospholipid molecules. 2. How does the arrangement of the phospholipids form a bilayer? The phospholipids arranged in two layers so that the charged phosphate heads interact with the water on either side of the membrane‚ and the

determine what effect an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers (nm)) thick‚ which is partially

Cell Theory In biology‚ cell theory is a scientific theory that describes the properties of cells‚ the basic unit of structure in every living thing. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are formed from pre-existing cells‚ and that the cell is a fundamental unit of structure‚ function and organization in all living organisms. It is one of the
