Cell wall

framework to support other structures. The structure of MBS’s walls are not load-bearing and consist of large areas of windows made possible by the concept of steel frame and curtain walls. Steel studs attract moisture, especially in Singapore with humid climate. The moisture can into the steel frame if we assume steel are not insulated, and then dewater on wallboard directly. The interior walls will reach a cold spots of moisture behind the wall. It is very expensive to maintain. Steel…

g. Integral proteins and Transmembrane proteins Ans: D 6. This portion of the cell membrane enables cell membranes to produce chemical products. . h. Enzymes 7. Which of the following is a function of a membrane protein that binds with hormones and neurotransmitters? i. Receptors 8. This type of membrane protein helps to anchor proteins in the plasma membrane of neighboring cells to one another. j. Linkers 9. The characteristic of plasma membranes…

The cell is the basic unit of life and is the smallest structure that can live an independent life. In 1665, Robert Hook was the first person to identify cells and name them. He also noticed that plants were made up of cells and this finding introduced the beginning of cell theory. Cell theory summaries Hook’s findings that cells make up all living organism, can only be produced from pre-existing cells and are the smallest living organism. The size of the cells is due a dependence on diffusion…

Introduction The human cell consists of three parts; the plasma membrane, the cytoplasm, and the nucleus. The plasma membrane is the outer boundary of the cell, it separates two major fluid compartments- the intracellular fluid and the extracellular fluid, and plays a key role in cell transport. Cell transport is the movement of materials across a selectively permeable membrane, and this process can occur in two ways; passive transport and active transport. Passive transport allows substances to…

In the abdomen, there are series of valves called ostia, which allow hemolymph to enter the heart and get pumped near the hemocoel. In mollusks, the hemolymph uses hemocyanin to carry oxygen. The oxygenated hemocyanin is blue. It is not part of any cell, it just hangs within the…

supports the theory of osmosis in biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound…

Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to…

Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

This can provide information about the way proteins move through cells, interact with other proteins, and implement their effects inside living cells (Stretton et al., 1998; Scott et al., 1998). Flow cytometry, specifically FACS when dealing with GFP tagged proteins, is a way to measure and sort proteins and molecules from a mixed biological sample based on…

First, I would like to say that the topic I chose is very interesting and in fact I really like this topic. Before choosing my topic I had rough idea about what CRISPR was and how it was being used in recent times to engineer everything around us by small steps. Before my research findings I had an idea what CRISPR was such as how it was being used around the world on modifying genes, and engineering new species by deleting or replacing the genes that were unwanted by that organism. What I knew…
