The sexually transmissible disease gonorrhea has become increasingly resistant to treatment with antibiotics. What is the most likely scientific explanation? a) The gonorrhea bacteria learned to avoid antibiotics b) The gonorrhea bacteria changed their genes when they sensed antibiotics c) Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrhea bacteria have flourished and persisted d) The antibiotic increased the mutation rate in the gonorrhea bacteria e) Both b and d 26. Which statement best describes the relationship between plants and animals on earth? a) Plants produce O2 and sugars from CO2 b) Animals produce CO2 and H2O from sugars and O2 c) Plants produce O2 and sugars and animals produce CO2 and H2O d) Animals produce O2 and sugars and plants produce CO2 and H2 27.
The path of the caribou is little slightly off its original course but that didn’t really harm them, in addition to that, the effect only applies to two of the twelve populate caribou pack. However the effect didn’t harm the caribou but the woodland cover did take some damage and couldn’t grow back to its original state. Also with the TAP replacing oil tanker transporting oil, have reduce the dead rate of animal by far half of the tanker would do. There also some research, what if road were to build across Alaska it would harm the environment greater than the TAP. Car, oil tanker, truck would pollute the environment when there is road traffic or not.
There is an expressive concern from the public about the cane toad epidemic and the impact on the natural ecosystem, domestic pests and native wildlife. Although not endangered, the cane toad is slowly declining in numbers due to the increase in human population and developing infrastructure. There are a number of conventional management methods including habitat manipulation, quarantine checks, detection and surveillance programs at the boundaries of their current locations and the public involvement in ‘toad hunts,’ all in an attempt to prevent their species further spread. These control methods have proven to be unsuccessful to the total eradication of the cane toad hence the current research by the CSIRO being undertaken to discover a bio control method of gene technology. The potential to battle the problem using parasites and diseases is being processed, however agencies have discovered that the work continues to acquire extensive studies including an assessment of the potential impact of the control agent on native wildlife, particularly native frogs, before the parasites and diseases could be used
This strategy was effective in stopping the spread of the disease. This concept, in which an adequate part of the general population is made to be immune to a disease through vaccination, thus making any spread unlikely, is called herd immunity. (CDC,2009) A third reason smallpox has been eradicated is that the World Health Organization (WHO) has assisted poor underdeveloped countries with effective vaccination programs. Not only has this eliminated the risk to those countries, but has also decreased the chance of travelers to these areas carrying the virus back to their own
The risk of toxic exposure to Malathion is minute, only a small application is used per acre placed on ground. According to the agency for toxic substance and disease, the long-term risk from Malathion application is unlikely. In conclusion, I vote to introduce Malathion into Genericville. I do believe with through proper education of our citizens, the over population of mosquitoes could be under control. Within the planning, we must take in consideration the river and wet lands; our water supply, possibly of residue being left over, and most importantly safety of
You often see in movies a patrol lasting less than a day. Is this accurate? We typically went into the bush for 2-3 week missions (same clothes) and then three days back at firebase. We stopped wearing underwear; it would give you crotch rot and socks would get wet and give you trench foot. Too hot for t-shirts or you got rid of your jungle fatigues top and just wear a t-shirt with sleeves cut off.
Treneice Lott Policing in American-7 Instructor, Joseph Pilliteri June 29, 2013 The two major less than lethal weapons that is use by law enforcement is pepper spray and stun guns. Pepper spray has an intense burning, breathing problems, and, temporary blindness and effectively disable your aggressor or attacker. Also, pepper spray can be effective on attacking animals to. The stun gun uses electrical current to the attacker and your assailant will have this intense pain and lose control of muscles. Stun gun is not lethal, but cause serious harm to someone with pace maker.
The mineralization and nitrification was low under buckthorn. In the discussion, they were able to prove that the invasion in the woodlands was identified as a major stressor in the systems. Removing the invasive species can be both a good thing and a bad thing. Removing the invasive species, it can cause a flourish of the native species since the invasive have been taking over the system’s resources. Removing the native species can also damage the system because the system might already get use to the invasive species being there in the
Celina Bongar Mrs. Wenger AP English Language C-10 19 September 2011 Unppeal to Reserve Nature In the passage of Silent Springs, Rachel Carson aims to raise public awareness about the dangers of pesticides with the goal of bringing about safer and more environment-friendly pest-management practices. The first part of the article describes the effects of parathion as an “universal killer”, which not only educated the annoying birds but also unintentionally affected other forms of wildlife. The immediate effects of the chemicals were devastating as well as their long term effects on the farmers who were exposed to these pesticides. The author provided the readers with examples of incidents that occurred in Indiana and California
Because they are hazardous. As in documentary they showed in an ad that fracking is safe. But what they mean by safe? If water, air and noise pollution are created by fracking then how it is safe! Fracking also created huge natural losses such as it crates pollution, destruction of forests to create its pipe lines.
