Biology – College Essay

Introduction Life on earth depends on the sun’s energy. Not only does the sun provide warmth and light, it is also the source of energy for the process of photosynthesis that is the most crucial chemical reaction on Earth (Deatsman, 2006). All living organisms obtain the chemical energy through the process of respiration that take […]

What reasons do Dunlap and Catton give for the neglect of the physical environment in mainstream sociology

There is a problem with the way humans interact and view their environment. This problem causes mankind to neglect, abuse and manipulate their surroundings with little or no regard for the consequences. Obviously, this causes many ills to all inhabitants of the forgotten earth, including humankind themselves. The latter is invariably recognized today by the […]

An investigation into whether varying light intensity at a stream affects the species diversity

Foulden common has a variety of different habitats including grassland, young woodland, ponds, swamps, fenland, set-a-side and streams which enables a diverse range of organisms to be present in an area. Life for plants and animals in any medium is a constant struggle. Besides the physical environment, predators, parasites and other competitors that have to […]

Taxonomy – 2695 words – College Essay

A species is a genetically distinct group of organisms, which can interbreed and produce fertile, viable offsprings. External similarity is the common basis for identifying individuals as being members of the same species. Yet a bulldog, a terrier, and a golden retriever are very different in appearance, but they are all dogs because they can […]

The effect of antibiotics on the growth of bacteria

The aim of this investigation is to find out what effect out of two antibiotics, penicillin and streptomycin has on the growth and multiplication of two different species of bacteria. The two different types of bacteria we will be using are E-coli and micrococcus luteus. The Apparatus:* Four sterilised Agar plates,* Glass spreader,* Masking tape,* […]

Mining for Gold and Copper using Biohydrometallurgy

Biohydrometallurgy is an application in mining which uses biology to aid metallurgy (as the name suggests). In its natural state a metal such as copper is found combined with other elements in the mineral chalcopyrite1. A bacterium is then used to form the compound copper sulphate (CuSO4), which in turn can be treated chemically to […]

Why Do Penguins Huddle

Hypothesis:I predict that penguins huddle to keep warm. This is because when they are all grouped together, the head radiated by those not on the outside will be transferred to the ones next to them, and vice-versa, so almost all heat loss is prevented. The other is insulation. With the penguins all standing next to […]

Distribution of Species in a field

The results of our research showed that the most daisies (common Bellis Perennis) grew in the middle-trampled area (48 daisy average), as opposed to our (my group’s) original predictions that they would grow in the least trampled area (36.8 daisy average). We were however correct when we predicted that there would be least daisies in […]

Fungal Pathogens in Humans

Though there are well over seventy thousand true fungal species that inhabit this planet, very few of these cause diseases in humans, called mycoses. Many more fungal diseases are associated with various plants and other animals. Mycoses in humans can range from superficial infections to deep-seated systemic infections that are life threatening. The superficial mycoses […]

To see how Blowfly larvae (Calliphora) react to light

The Blowfly is any member of the insect family Calliphoridae (order Diptera). They are metallic blue, green, or black in colour and are noisy in flight, producing a distinctive buzzing sound. The blowflies are on average 8-10 mm in length, slightly larger than the more common housefly larvae. Among the blowfly family, the more important […]

How does Cystic Fibrosis affect the gas exchange system digestive system and reproductive system

Every cell in the body needs different proteins for specific functions. DNA determines the structure of the protein. If DNA or RNA changes the structure of the protein, used for a particular function, due to wrong transcription or translation of protein synthesis, mutations occur. These mutations can lead to genetics disorders or genetic diseases.Cystic Fibrosis […]

Investigating Osmosis in potato cells

Aim:To investigate the effect of varying the concentration of sucrose solutions and to see if osmosis occurs in potato cells. Research/definition:Osmosis is the diffusion of a solvent through a semi permeable membrane from a region of low solute concentration to a region of high solute concentration. The semi permeable membrane is permeable to the solvent, […]

Immunostaining and In Situ Hybridization

The study of gene expression provides invaluable insight into an organism’s structure and function; how it is that from a mere embryo genes can control which cells, tissues, organs and limbs will develop, providing the organism with the inherited traits that specifically adapt it to its forthcoming environment. Mutations of particular genes are sometimes associated […]

DNA research paper

I. Introduction Over the course of the last few weeks, we conducted experiments in which our goal was to successfully ligate EGFP cDNA into pET41a(+) in order to transform our recombinant expression plasmids into clones of E. coli. After growing these cultures on varieties of agar plates, we attempted to isolate our recombinant plasmid DNA […]

Two-component signalling pathways in bacteria

Experiencing “life on the edge”, bacteria have to respond to changes in the environment in order to survive. Facing limited resources and coupled with intense competition in almost every environment, bacteria have to accommodate any potential energy sources of nitrogen, carbon while resisting toxicity to their regulatory process and metabolism. By establishing an intra and […]
