Discuss the role of negative feedback in living organisms and how it benefits these living organisms? (25 marks) Negative feedback is the process by which changes occur to bring an organism’s internal environment back to the normal level. One example of negative feedback in a living organism is the ways humans regulate their blood glucose levels. I will firstly discuss the processes that occur as a result of blood glucose levels being too low. When blood glucose levels are too low the pancreas

Corinne N Bryant May 2‚ 2013 University of Phoenix The lives of the organisms in the desert require a substantial amount of survival skills. The temperature in a desert biome is always very high and it does not rain very often so it is also extremely dry. Any organisms that live in the desert must be able to adapt to these conditions in order to live. For example‚ one organism that can be found in the desert is cacti. Cacti roots are closer to the surface than other plants so it is able

How are organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In

How bacteria can affect the lives of humans and other organisms Bacteria can enter the body in 3 different ways. Through the gas exchange system‚ by breathing in pathogens‚ most are trapped in the mucus lining in the lung epithelium. There are also cilia that move the mucus up the trachea and into the mouth where it is removed. However some bacteria is still able to reach the alveoli where they invade cells and cause damage. Another way it can enter the body is through the skin‚ if the skin is

Internal Structure of the Stem The internal structure of the stem is usually more complex than the other plant organs for it performs and provides various functions. These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem.

Use-Case diagram for a Library Management System. Introduction: Capturing the dynamic behaviour of a system is one the key aspects to create a model. Dynamic behaviour means the behaviour of the system under operation. Use case diagrams are used in Unified Modeling Language‚ a standard modelling language for the modeling of real-world objects and systems. A use case diagram is to explicitly define the working of a system with in a system boundary. Each system is primarily divided into two main components
