What is the name given to organisms that can make their own food and thus sustain themselves without consuming organic molecules derived from other organisms?Are food and reproduction the only goals of primitive life forms like plants and cells?A...
The SPGJ model exhibited a minimal pressure drop during the passage of food from the lower esophagus to the jejunum, thereby easing the resistance to food expulsion. The CGJ model exhibits a particle retention time 15 times exceeding that of the SPGJ models, while the respective average ...

There have been claims that GM herbicide-tolerant crops are more environmentally friendly because they allow farmers to adopt no-till systems, decreasing the need for mechanical ploughing and potential soil carbon loss. However, GM crops are not needed to practice no-till, and their introduction ha...
more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly. There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costin...
Available energy due to disequilibrium within a system can be used to produce mechanical work. It can only do so, how- ever, when it is constrained—left unconstrained, free energy is lost as the system goes to thermal equilibrium. Thus, the key to the ability of a system such as a ...
(GMOs). Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food ordrugproduction, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests anddisease, greater food security, and medical benefits to the world's ...
