Gross primary production, community respiration, and net primary production as measurements of metabolism at Devereux Slough: When do physical processes dominate? Introduction In any given aquatic ecosystem, a balance between photosynthetic activity and anaerobic respiration encompasses the general assumption of metabolism – where gross primary production (GPP) is defined as the assimilation of inorganic carbon … Read more
Leaf area index estimation from allometric relationships in Cucurbita pepo L. Prediction of leaf area is essential in crop simulation models. The objective of this study was to find relationships between leaf area index (LAI) and numbers of leaves (NL), leaf dry weight (LDW), leaf fresh weight (LFW), number of nodes (NN) and plant height … Read more
Abstract: Plants are essential organisms in the environment, using the sun and CO2 to produce oxygen. This is the process of photosynthesis. Plants are producers, meaning they are able to provide themselves with the nutrition they need to thrive. When plants have an abundance of carbon dioxide, they thrive in performing light reactions and the … Read more

6 Very few fossils records of the largest plant family Orchidaceae exists which makes the plants present in this family difficult to classify. However, fossils leaves of two plants, Dendrobium and Earina, were obtained from New Zealand. The finding of these two orchid leaves is a major breakthrough in the field of botany. It will … Read more
Seaweeds are marine macroalgae that are found in coastal areas around the world. Seaweeds typically grow in the intertidal zone where light allows a sufficient amount of growth for seaweeds through photosynthesis, as all seaweeds contain chlorophyll and are photosynthetic (The Seaweed Site, 2016). Seaweeds are usually found attached to hard substrates, as their environment … Read more
Abstract In the lab tested, the hypothesis that temperature affects the rate at which substrate is converted into products using the enzyme beta-galactosidase (BGz) and the substrate O-Nitrophenyl-β-D-galactopyranoside (ONPG) The enzyme BGZ is found in a variety of living organisms all the way from bacteria to humans. The byproducts are glucose and galactose. Its common … Read more

But its origin is shrouded by 7 controversial end member hypotheses. 8 9 It is generally agreed upon that the foundations of vertebrate success hinged … Read more
Animals and humans move around to survive and having the ability to navigate this complex environment represents one of the most fundamental cognitive functions. It involves basic, perceptual and memory related processes and spatial navigation, which is significant as it is a multisensory process where information needs to be integrated, this ability can vary in … Read more
Population outbreaks of the crown-of-thorns sea star (Acanthaster planci), remain one of the major causes of coral destruction and habitat degradation on coral reefs throughout the Great Barrier Reef (Grand, 2014) Given the threat posed by this poisonous echinoderm to coral reefs, significant investments have been made to reduce the number of Sea Stars and … Read more
Introduction When both anions and cations in a solution combine, a precipitation reaction will occur to form a precipitate. Precipitates are ionic and insoluble solids that are the product of a precipitation reaction, an example of this is when carbonate ions in solution react with a solution containing magnesium ions, forming a precipitate, this can … Read more
The nervous system allows us to communicate with the outside world while controlling many internal mechanisms at the same time. It is made up of all the nerve cells in your entire body, and by taking in information through our senses, it processes the information and triggers reactions, allowing your muscles to move or causing … Read more
Light is a symbol of life and well being, without it nothing exists. It brings in sunshine for civilians to be able to see and enlighten their mood.

The study of consciousness is problematic and, in order to combat this, has become an interdisciplinary effort that touches upon a plethora of aspects of human cognition and brain function. Originally, a neurological approach looking at selective deficits in patients was adopted to learn about normal and abnormal brain function. Of late, there has been … Read more
