Biology – Pattern in Nature 1. Organisms are made of cells that have similar structural characteristics 1.2.1 Outline the Historical development of the cell theory‚ in particular‚ the contributions of Robert Hooke and Robert Brown. • 1665 English scientist Robert Hooke used microscope to examine thin slices of cork and saw small box-like compartments he called cells. He was first to realise plant material had organised structure at microscopic level. (compound microscope) • 1831 Scottish Botanist

- BIOLOGY ASSIGNMENT Aim: To investigate the types of producers and animals in the tidal rock-shelf ecosystem and the adaptations of organisms in that environment. Also‚ to measure biotic and abiotic components and the distribution and abundance of organisms to the tidal rock- shelf ecosystem. Introduction: Long Reef Marine Reserve was established in the 1980’s to protect the extremely diverse marine life that makes the most of this environment. The Marine reserve covers the large rocky

Biology Virus Essay A virus is a microorganism that cannot reproduce without a host. As a result of this‚ there has been a lot of controversy on whether or not a virus is a living or non-living organism. The dictionary.com definition for life is‚ “the condition that distinguishes organisms from inorganic objects and dead organisms‚ being manifested by growth through metabolism‚ reproduction‚ and the power of adaptation to environment through changes originating internally.” Viruses have characteristics

March 5‚ 2013 Biology 1111 Term Paper Glycolysis and the Citric Acid Cycle Glycolysis occurs in the cytoplasm outside the mitochondria‚ it is a metabolic pathway that is the breakdown of glucose (C6) and ends with 2 pyruvate (C3) molecules. Energy is invested to activate the glucose‚ 2 ATP are gained‚ and oxidation results in NADH‚ which will be used later for additional ATP production. Glycolysis is divided into (1) the energy-investment step‚ when ATP is used; and (2) the energy-harvesting
