Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

One purpose of this paper is to show the importance of biology in our everyday life. The subject of this paper is the cause and affects of micro-organisms that are in the human digestive system. Article of choice‚ (Adnan‚ 2010) Benefits of Microorganisms to Humans‚ Retrieved February 8‚ 2013. This article was of interest because there are many bacteria that we encounter in our daily lives and it was informative to know that all bacteria is not bad. In fact‚ there needs to be a balance between the

Business Challenge/Background With the number of resort guests increasing it is becoming more difficult to keep track of the survey responses. The current survey process is a very manual process that causes a delay in reporting and identifying areas of the resort that require improvements. In addition there is hazard with the limited storage space at the resort. The resort has already received a warning from the Fire

E-R Diagram Introduction:- In 1976 ‚Chen developed the Entity-Relationship Diagrams ‚a high-level data model that is useful in developing a conceptual design for database . An ER diagram is a diagram containing entities or “items”‚ relationships among them‚ and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community‚ it is considered a natural and easy-to-understand way of conceptualizing the structure of database.

Genetic Modify Organisms Genetic Engineering Today many scientist use “genetic engineering” a new technology that manipulates the genes of many plants‚ bacteria and animals. This organisms are called genetic modified organism (GMOs) because their genetic material (DNA) has been changed in a way that it doesn’t occur naturally‚ it alters the organism’s genetic material through adding‚ deleting or changing the segments in the DNA. This technology is also referred to as "biotechnology" or "recombinant

Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

DFD Yourdon Recently reviewed In the late 1970s data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations

A Human Is A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism.The same type of cells which carry out a specific function are organised into a tissue. For example‚ a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body

Sabao BS Biology I-A .Lab 1 August 01‚ 2013 INTODUCTION A pond is a body of freshwater smaller than a lake. Ponds are naturally formed by a depression in the ground filling and retaining water. Streams or spring water is usually fed into these bodies. They can also be man-made ponds which can be created by damming a stream‚ digging a hole. Ponds are usually
