The symbiotic relationships that establish involving the roots of major plant species and fungi are called Mycorrhizae. These symbiotic relationships differentiated by the two-way movement of nutrients whereby carbon runs to the fungus. The fungus then facilitates the movement of the inorganic nutrients towards the …
All cells need to have a constant energy supply. The two processes by which this energy is attained from photosynthetic materials to form ATP are cellular respiration and fermentation. (Hyde,2012). Fermentation is a way of harvesting chemical energy that does not require oxygen. (Reece et …
Different methods have been used and are being used in the analysis of archaeological data. Among others, different archaeometric fields such as paleoecology (paleozoology, paleobotany and pllenanalysis), dating methods (radiocarbon-dating and dendrochronology) and analytical chemistry had been used for the evaluation of the quantity and …
Abstract In this paper we look at reptile reproduction and the how the different factors and processes involved vary in different species. We look at: Reproductive cycles Spermatogenesis and oogenesis Copulation and Fertilization Egg shells Ovoviviparity Viviparity Parthenogenesis Parental body condition Reproductive behaviour Parental care …
Civilization is a flow of billions of human beings, but it is only few who take up the task of developing it. It is purely their hard work that secures, augments, ramifies and manifests the lives of the rest. (more…)
The term ‘antibiotics’ refers to substances that kill bacteria or prevent their growth. Antibiotics are natural substances that are released by bacteria and fungi into their environment to fight other organisms. The use of antibiotics by organisms therefore represents chemical warfare on a microscopic scale. …
There are 3 biological rhythms in the body. Circadian, which is our body clock which works to a 24-hour cycle and regulates our bodies biochemical, physiological and behavioural processes. Ultradian processes, which are smaller processes that happen inside our 24-hour circadian cycle. These Ultradian cycles …
Introduction The world of science and the public at large were both shocked and fascinated by the announcement in the journal Nature by Ian Wilmut and his colleagues that they had successfully cloned a sheep from a single cell of an adult sheep (Wilmut 1997). …
Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule, such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, …
Introduction Sordaria fimicola is an ascomycete fungus studied for its product of meiosis and mitosis that form 8 haploid spores. These spores are contained in a fruiting body called perithecia. Asci made up of spores are contained in this body. The perithecia are squashed in …
Student Name: Kwok Matthew Chun Wai Discuss the advantages and disadvantages for plants of living in an aqueous environment compared to a terrestrial one? Introduction: Plants are commonly classified to two main types: aquatic plant and land plant. They have different features to adapt the …
Introduction Helicobacter pylori are a species of epsilon proteobacteria which colonizes the harsh environment of the human stomach. Its name refers to both its spiral shape (Helicobacter) and the area of the lower stomach which it habitually colonizes: the gateway (pylorus) between the stomach and …

All cells are designed to perform a particular job within an organism, that is, to sustain life. Cells can become specialized to perform a particular function within an organism, usually as part of a larger tissue consisting of many of the same cells working together …
Biological Theory of Aging Tick tock, tick tock, what’s that sound? According to this theory, it’s your biological clock, ticking away at a predetermined rate. This theory says that DNA, the cells’ genetic material, holds the key to your planned demise from day one. While …
1. 2: Using one or more examples, explain effects of neurotransmission on human behavior: Our nervous systems consist of between 10 to 100 billion neurons; each of which making 13 trillion connections with each other through electrochemical messages that allow people to respond to stimuli, …
The Autonomic Nervous System regulates cardiovascular, respiratory, digestive and urinary functions. The ANS studies have changed medicine practices. Before, the thought of a myocardial infarction patient living past five years was unheard of. Now doctors have learned to manipulate the ANS system with drugs that …
Biology is defined as the study of life while psychology examines the human mind and its processes, especially those affecting behavior. Biological perspective links biology and psychology by focusing on the analysis of human behavior based on biological and physical evidence.
Why is biology important? As a field of science, biology helps us understand the living world and the ways its many species (including humans) function, evolve, and interact. Advances in medicine, agriculture, biotechnology, and many other areas of biology have brought improvements in the quality of life.
Chemical biology deals with how chemistry can be applied to solve biological problems while biochemistry is the study of the chemistry of biology. In general, the chemical biology major focuses on small molecules while the biochemistry major focuses on proteins and nucleic acids.
