Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

Biology project Measuring Light Intensity Soil moisture and soil pH meters are also available - both are used by simply pushing the probe into the soil and reading themeter. Errors can be made when measuring abiotic factors when the soil moisture or pH meter probes are not cleaned between readings. As always the results can be made more reliable by taking many samples. Here are some examples: Daisies The more light available‚ the more daisy plants will be present.0 This is because daisies

nucleus‚ while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the arrangement of chromosomal DNA. Prokaryotes were the only form of life on Earth for millions of years until more complex eukaryotic cells came into being through the development of evolution. Animal Cell vs. Plant Cell Both Plant and Animal cells have cytoplasm. Both Animal and Plant cells have nuclei‚ ribosomes‚ mitochondria

Biology What is cholesterol? Cholesterol‚ a waxy substance produced by the liver and found in certain foods‚ is needed to make vitamin D and some hormones‚ build cell walls‚ and create bile salts that help you digest fat. our liver produces about 1‚000 milligrams of cholesterol a day‚ enough cholesterol for the body to be ok without food with colesterol but it’s hard to avoid cholesterol entirely because so many foods contain it. Consequences o high cholesterol. Too much cholesterol in the

Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts
