Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential

probes successfully landed on the surface of the Venus. However‚ the essential equipment on probes was damaged‚ leading to that it failed to get insight into the surface of the Venus. While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger

Jaycar Electronics Reference Data Sheet: BATTPRIM.PDF (1) PRIMARY CELLS & BATTERIES Many portable electrical and electronic devices are designed to be powered from batteries and in a lot of cases‚ from primary or non-rechargeable batteries. This is the familiar kind of battery which has a fixed amount of energy stored in it during manufacture‚ and once that energy has been used up the battery is simply thrown away and replaced. There are many different types of primary battery now available

Animal Cells Vs. Plant Cells There are quite a few similarities and differences between plant and animal cells. Whether it be the internal parts of the cells‚ or the processes they go through. They also have differences in shape and sometimes size. These are only a few examples of similarities and differences between the two different cells. To begin with‚ both animal and plant cells are eukaryotic cells. This means that both cells have the same internal features‚ such as a cell membrane‚ a nucleus

Experiment title: Preparation of Biological Materials for Microscopic Examination Objectives: 1. To learn how to use a microscope. 2. To study the cell structure of starch grains‚ onion cells and cheek cells. 3. To differentiate the difference between starch grains‚ onion cells and cheek cells. Introduction: Microscope is an optical instrument use to magnify micro objects that hardly or impossible to be observed by naked eyes‚ so that the objects can be studied. Compound light microscope

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole‚ a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell’s turgor‚ controls movement of molecules between the cytosol and sap‚ stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose‚ pectin and in many cases lignin‚ is secreted by

Biological Membranes: A simulation Introduction Diffusion is the process by which collisions between molecules cause to spread apart. This movement is described as movement from an area of greater concentration to an area of lower concentration. Hence‚ diffusion continues until the molecules are equally distributed. This is to ensure that molecules have reached a state of equilibrium. Diffusion occurs spontaneously‚ no energy is involved. In cells‚ Diffusion occurs through cell membrane which is
