Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating…

where DNA is structurally in the cell is different between prokaryotes and eukaryotes. In prokaryotes, the DNA is in the cytoplasm, but specifically it is concentrated in the nucleoid region. In eukaryotes, the DNA is all contained and stored in the nucleus. Prokaryotes and eukaryotes also contain ribosomes. Ribosomes are small, roughly spherical organelles without a membrane that are responsible for assembling and building protein. Ribosomes are composed of protein and RNA molecules. Just like…

After being incubated in a water bath at 37 degrees Celsius for 20 minutes, the 8 samples were centrifuged at 400 rpm for 5 minutes and collected for observations. Presence of a red pellet in the first 7 tubes, including control Test Tube 1 were noted, while the red pellet was absent in control Test tube 8. It must also be noted that the pellet became progressively smaller as each successive tube was examined, a result more noticeable after examination of Test tube 5, as seen in Figure 1. The…

In 1635-1702 a physicist named Robert Hooke was the first inventor of the microscope. He first observed thin slices of cork, which he described to be as small rooms, the ones that were similar to the small rooms in monasteries. He only saw the cell wall because cork cells are not alive. After the discovery of the microscope in 1635-1702 by Robert Hooke, another microscope inventor named Anton Leuwenhoek, he discovered the microscope that can magnify things in 1675, and he also discovered the…

II. Method Concentration Gradients Experimet1: In this portion of the experiment, a beaker was obtained with 50mL of water, and it was sat until the water stopped moving. A small crystal of potassium permanganate dye was gently put into the water at the center of the beaker. Then the observation was recorded for the next 5 minutes. Experimet2: In this portion of the experiment, a beaker was obtained with 50mL of water in room temperature, and a teabag was placed into a beaker of water. The…

Cellular manufacturing is an application of Group Technology in which machines or processes have been aggregated into cells, each of which is dedicated to production of a part or product family or limited group of families. Parts with similar processing requirements are identified; these are then placed into logical groups called part families and the equipment requirements for each part family are subsequently determined. A part family is a collection of parts which are similar either because…

Chapter 2: The Beginning From Conception to Birth, first talks about how our life begins. Every human being starts with a single cell called zygote. (Berger, pg48). All living things consists of cells that has molecules of DNA. DNA molecules are called chromosomes. Then, this chromosomes contain genes. Each one of us has 46 chromosomes that are arranged into 23 pairs. Except for our reproductive cell called gamete. There are two different types of gametes, for a man it is called sperm and for…

The nucleus is in the center of all eukaryotic cells and is a very important part. The function of the nucleus is to be the control center of the cell and contains most of the cells DNA. Chromatin and chromosomes are also contained within the nucleus. The nucleolus is a small, dense region that is located at the center of the nucleus. The nucleolus' function is to make ribosomes, "the beginning". The nuclear envelope is made up of two membranes, which surround the nucleus. The nuclear envelope…

are intermediate filament proteins necessary for function and structural integrity of the nucleus. Lamins consist of an amino-terminal head domain, a coiled-coil central rod domain and a carboxy-terminal tail domain (Fig. 1A). They form dimers by rod domains and then associate in head-to-tail polymers creating complex network conjunction with other proteins located underneath the inner membrane of the nucleus. Mutations in the LMNA gene affect lamins dimerization and assembly (Bank et al.,…

In order to keep living organisms healthy cells have to go through many stages to replace damaged or worn out cells. One of the necessary steps is mitosis. Mitosis is the process of the body cell and nuclei dividing. This division is the cause of bodies growing and cells repairing. This division is a continuous process which there is four major steps; prophase, metaphase, anaphase, and telophase. Mitosis is comprised of prophase, metaphase, anaphase, and telophase. In prophase chromosomes…
