Natural human caused Disasters 1. The rig’s malfunctioning blowouts preventer ultimately failed‚ but it was needed only because of human errors. Those errors originated with a team of BP engineers in Houston‚ such as 1. Fewer barriers to gas flow 2. Fewer centralizers to keep cement even 3. No bond log to check cement integrity 4. Pressure test misinterpreted 5. Mud barrier removed early 6. Blowouts preventer failed. 2. In the months following the Gulf oil disaster‚ wildlife managers‚ rescue crews

are curvature movements caused by differential or unequal growth in plant organs‚ which results in their bending in the direction of a particular stimuli‚ for instance light. Such movements which are induced by external stimuli are called trophic movements. A trophic movement of plant organs in response to the source of light is known as Phototropism. The stem grows towards the direction of light‚ and is therefore said to exhibit positive phototropism. For instance‚ we have observed that shoot apices

Can lungs evolve like humans lungs are in part of the body without lungs many species or organisms would die because lungs are like the heart and the brain you can’t leave without any of this organs also almost all living organisms have two lungs because they are special to organisms. Lungs can evolve because when the body of the person or an organism evolve they need to evolve too because then why

Bt-corn and its Effects on Danaus plexippus Recently‚ in response to the chronic problem of insects destroying crops and from the known effects of pesticides on humans and on the environment‚ a new form of insecticide was discovered‚ particularly for corn. In this new case‚ the organism itself is genetically modified for protection. This insect-resistant corn is the new Bt-corn and contains genetic material from the donor organism‚ a bacterium. Bacillus thuringiensis contains a protein that kills

10-15% alcohol produced from corn‚ some say the price of food has risen‚ causing hardships‚ increased food prices‚ and other problems. Ethanol has been blamed for the rise of food prices. Since corn is used for many different things such as food for us‚ ethanol gasoline and food for animals. Even though ethanol lowers our gas mileage corn is being used more for ethanol and making it more expensive for the people who would like to eat corn on a cob. In 2013‚ 40% of corn and other crops went to produce

According to Raup (1991‚ p. 3f)‚ “except that the human species still living literally forever‚ it will some time stop to exist. The future of humanity is easy to explain about extinction such a long-term. An estimated 99.9% of all species that ever existed on Earth are already extinct.” There are two distinct ways in which the human species could become extinct: first‚ it is by evolving or transforming into one or more new species or life forms‚ amply particular from what came before so as

Genetically modified corn‚ Gasoline and High fructose corn syrup Did you know that about 85% of our corn is genetically modified (True Food Network)? It’s really surprising how genetically modified food has been incorporated into our society. We eat genetically modified food every single day whether it would be yogurt‚ fruits‚ milk‚ peanut butter‚ etc. So what is genetically modified food‚ according to “Non-GMO shopping guide”‚ genetically modified food (also known as GMO) is define as “the result

Similar to Roosevelt‚ there are many people in both history and literature who have been plagued with an illness or wound. These people either step down to the wound‚ or learn to overcome it. The “Unhealable Wound” is a reoccurring archetype in literature‚ expressing an injury or defect that a character must learn to beat in order
