In Planet of Slums‚ Davis discusses the roots of slums in relation to urban poverty in the post-modern era as well as its social‚ political‚ economical and ecological consequences. This essay might ring a bell to many as a duplication of the famous UN-HABITAT’s report in 2003 on the challenge of slums; however in my opinion‚ what Davis is attempting to do here is an exploration to the roots of urban poverty on a global scale rather than within local state governance‚ and also with references to the

The Effects of Herbicides on Aquatic Organisms Anthony Cerda John Jay Science and Engineering Academy Abstract In this experiment different herbicides were added to aquatic organisms. The organisms used were protists and bacteria which are microscopic organisms (Microorganisms). Herbicides are chemicals used to control certain plants such as weeds. Two hypotheses were tested in the experiment.H₁) The herbicides will affect the population growth rate of the microorganisms and H₂) The adding

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

grow to 65 meters in length. Most are photosynthetic likeplants‚ and "simple" because they lack the many distinct cell and organ types found in land plants. The largest and most complex marine forms are called seaweeds. Though the prokaryotic cyanobacteria are informally referred to as blue-green algae‚ this usage is incorrect [3] since they are regarded asbacteria.[4] The term algae is now restricted to eukaryotic organisms.[5] All true algae therefore have a nucleus enclosed within a membrane andplastids bound

A) translating polypeptides directly from DNA B) using fewer kinds of tRNA C) having only one stop codon D) lengthening the half-life of mRNA E) having a second codon (besides AUG) as a start codon a 5) A particular triplet of bases in the template strand of DNA is 5’ AGT 3’. The corresponding codon for the mRNA transcribed is A) 3’ UCA 5’. B) 3’ UGA 5’. C) 5’ TCA 3’. D) 3’ ACU 5’. E) either UCA

forms of bacteria can cause deadly diseases like salmonella‚ a food poisoning that is very deadly. There are some major phlyuhs Chlorobia-and cyanobacteria are shaped like rods‚ spirals and are anaerobic. They do contain chloryphyll and can produce their own food through photosynthesis. Not all have to use sunlight to induce that process. Cyanobacteria give out oxygen. Proteobacteria- These live on the roots of some platns and transfer nitrogen from the air to the soil. This phylum contain bavteria

3. Explain how the products of photosynthesis are transported‚ partitioned and allocated during plant growth and reproduction. Photosynthesis has been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process‚ similar to respiration and fermentation‚ in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central
