Certain antibiotics are also developed to kill certain human cells and are used to cure cancer. All these features of antibiotics are a huge advantage but on the other hand, they have certain disadvantages. Overuse or misuse of antibiotic can cause side effects and can also make the pathogen resistant to the medicine. Some antibiotics kill the good bacteria in the body that are actually helpful in various life processes we carry out. In case of vaccines, the major advantage is the fact that vaccination prepares the immune system against the injected pathogen and of a similar pathogen happens to attack the body in future; it won’t be able to harm the body.
 There are microbes, which are beneficial to the human in production of food or the medical and pharmaceutical field. Microbes are biologically wired to carry out certain functions. Some of these functions are – being able to pass on the entire genetic information to the next generation, produce viable offspring to prevent extinction, and lastly being able to adapt and change to environmental changes so that any dire change would not be able to wipe off the entire colony. However there are also microbes that cause harm to the human body. These harmful microbes are termed as pathogens.
One of the most difficult challenges that faces our society about water pollution is cleaning after a body of water have been contaminated. Our design team aimed to design a sufficient water filter that would improve the water quality in a body of water have been contaminated. An ideal body of water should be contaminant free, with a high potential Hydrogen (pH) and Nitrogen Dioxide (DO) level. Low pH and DO level which could cause health hazards to individuals who used the water as a drinking water. 2.
The bacterial plates also suggested that Ampicillin was ineffective in killing the bacteria, as zones of inhibition were not present, despite using two disks of this drug. These results could possibly be explained by the properties of these antibiotics and the bacteria used in the experiment. Bacterial enzymes, such as beta-lactamase, cannot be broken down by Ampicillin. The bacterial plasmid carrying this enzyme disables the Ampicillin placed in the agar, allowing for more bacterial growth. In this case, it is
If the water source is not properly treated, health risks and problems could arise. Based on the facts and findings form journals, I would conclude that recycled water is used only for nonpotable purposes. Furthermore, recycled water provide many environmental benefits such as decreasing the diversion of water from sensitive ecosystems. To conclude, recycled water has a lot of nutrients such as nitrogen and very useful for irrigation which allows reduce putting of synthetic fertilizers.. This could also lessen and prevent
One may ask how this is possible. To answer that, the University of California in San Diego ,taken from livestrong.com ,explains how crops are made insect resistant; this is achieved by adding a toxic bacterium to the genetic makeup of the crop. Being that the case, this does not, in any way, put the health of humans in any danger. GMOs are also environmentally friendly. This happens in a sense that they, GMOs, help in reducing environmental pollution and soil erosion.
Antibiotics selectively target bacteria for eradication as opposed to the host’s cells by acting on things that are particular to bacteria. A number of bacteria produce peptidoglycan that makes up their cell walls. Human cells don’t produce nor need this this, so antibiotics that target peptidoglycan destroy the bacteria without harming good cells. Metabolic pathways are another route in which bacteria are damaged without the host cells. Sulfonamides prohibit bacteria from producing folic acid which is critical to the survival of cells.
Escherichia Coli aka E. Coli, has the ability to absorb and contain uranium. Although there are strains of it that can cause disease, this can handle nuclear waste. While it would be good if this bacteria did disappear, nuclear waste spills could get out of hand. For example, if a spill had gone into the ocean, this could potentially get into our water supply and harm marine animals. By harming the marine animals, they could eventually mutate or become harmful to us when consumed.
Eliminating the plastic bottle will protect humans against these toxic chemicals. Tap water has substantial evidence to support it. Tap water is less susceptible to the effects of toxic chemicals than bottled water and overall superior to bottled water. Drinking tap water instead of bottled water has many environmental advantages. Safety is the principle concern when debating this topic, especially when people think about their families’ well-being.
I use to think pesticides are good because they kill pests, but now I have learned that pesticides are awful to the wildlife, soil, and waterways. Due to pesticides being in the water we drink and in the food we eat, I think it is possible to trace amounts of pesticides in our bodies. “Silent Spring” by Rachel Carson calls the readers attention to the issues of pesticides and gives them knowledge on this subject. Pesticides put chemicals into the soil and waterways that hurt the environment. This causes plants and animals to become affected by these chemicals.
