In Chapters 1 and 2 of “Full Planet‚ Empty Plates”‚ Lester Brown argues that the world population is increasing and food is becoming more scarce. I agree with both of Brown’s arguments because the increasing world population correlates with the growing scarcity of food. Chapter 1 discusses the rise in food prices and scarcity of food. While food is becoming more expensive and scarce‚ people are becoming more hungry. As people cultivate more land‚ the soil becomes depleted‚ and is then harder to

gram-negative and gram-positive bacteria are and what it’s composed of. Gram-positive bacteria take up the class of bacteria that stain crystal violet in the method of bacterial differentiation. Where gram-negative bacteria are a class of bacteria that does not retain crystal violet. Instead they are counter-stained pink by Safranin‚ and because of this‚ identifying positive is possible. One of the many differences between gram-negative and gram-positive bacteria is their peptidoglycan. Which are

Raudah P. Mangbisa Grade VIII-Nilo VIRUS A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms‚ from animals and plants to bacteria and archaea. Characteristics: Like living organisms‚ viruses contain nucleic acids and proteins. Inside living cells‚ viruses can reproduce‚ but not by the process of mitosis like most living cells. Viruses lack some characteristics of living organisms. Outside of living cells‚ viruses are

opinion article‚ Laws Will Not Change P-Platers‚ published in the Herald Sun on the 17th of January 2008‚ notes in a calm‚ informal and rational tone‚ that no laws restricting the freedom of P-Plate drivers will help. Martella uses a rational but concerned tone to encourage the reader to agree that restricting P-Plate drivers will not lower road fatalities. This is evident when she uses statements such as‚ “no restriction law will ever change the maturity and attitudes of drivers.” This calms the reader

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

Botulism Botulism is a bacterial disease most often linked to un-sterile canned foods. It can be rather serious‚ as it has the potential to paralyze the respiratory system and thus cause death. The bacterium is named Clostridium Botulinum‚ it is a gram-positive and anaerobic pathogen. The morphology consists of rod shaped spores. The toxin is widely used in cosmetic injections‚ also known as Botox‚ to decrease wrinkles in the skin. Though Botulism is mainly linked to canned foods
