It started with my love for animals and nature when I was little. Tissues are made up of groups of cells that all have a similar function and structure. Some of the smallest are one-celled bacteria, which are too small to see with the naked eye, at 1-millionth of a meter (micrometer) across. Bacteriophages have gained attention as alternative antimicrobial entities in the science community in the western world since the alarming rise of antibiotic resistance among microbes. All cells arise from other cells, by binary fission in prokaryotic cells and by mitosis and meiosis in eukaryotic cells. The study of interactions between organisms and their habitats is called Ecology. All cells have a cell-surface membrane and, in addition, eukaryotic cells have internal membranes. The population of living organisms would be overloaded if biological interaction didnt exist. Milk Sickness Today, However, if the P53 gene, a tumour suppressor gene, becomes mutated, these caspases may form with a different tertiary structure, meaning that the cell will not undergo apoptosis and will continue to divide uncontrollably .

The essay is not just a memory test of what a student knows - it is also a test of whether they have some understanding of what they have learnt and can applywhat they know. A few of these are discussed below. Ecosystems are biological populations of interacting organisms and their physical surroundings. To say that everything is left up to biology would be a mistake, even in the eyes of Edward Wilson. Predation involves predators and prey, such as a fox catching and eating a rabbit. An example of this kind of signaling through growth factor receptors is provided in chapter 10 and illustrates how signal transduction initiated by a growth factor can control the process of cell division through a kinase cascade. Interspecific is the competition between organisms of different species, such as what would happen for food and survival in a predator-prey relationship.

A fungus and an alga live closely together to form a lichen, together the fungus and the alga are able to survive in harsh environments where neither organism would be able to live on its own. T helper cells also directly interact with macrophages, cells that engulf foreign matter and display antigens on its surface. Biological membranes allow life as we know it to exist. There are many different types of interactions that can take place in which some organisms benefit and some are harmed. The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes.
