The bulk of genetically modified organisms used in agriculture are called what?
These are usually called GMOs. An organism that is produced through genetic engineering is considered to be a genetically modified organism (GMO).Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. Genetic engineering is also called genetic modification.While there is a worry among the public that eating genetically modified food may be harmful but scientific agreement is that these crops are no greater risk to human health than conventional food.

What is biotech crop?
A biotech crop is one that has been genetically modified to express a desired trait. This may include insertion of a gene(s) that codes for natural pesticide production, increased nutritional value, drought/frost resistance or greater yield.
The environmental and health risks associated with ground level ozone are greater than the environmental and health risks associated with the depletion of ozone layer?
No, it is false. The environmental risks with depletion if stratospheric ozone are greater.
What is environmental turbulence?
Environmental turbulence refers to the amount of change and complexity in the environment of a company. The greater the amount of change in environmental factors, such as technology and governmental regulations, and/or the greater the number of environmental factors that must be considered, the higher the level of environmental turbulence. For many reasons environmental volatility and instability have been increasing for the past 100 years.
How does temp affect animals?
lower or higher environmental temp than body temp makes the animal's body work harder to maintain body temp (i.e., greater energy expenditure)
Why are small populations difficult to preserve?
The reason small populations is difficult to preserve is because when a small population of animals interbreed, there is a greater risk that harmful genetic conditions can appear in the animals. This is one issue that scientist face when trying to preserve endangered species. One way to lower this risk is to be sure that genetically-similar animals do not breed.
What is conventional farming?
Conventionally grown is an agriculture term referring to a method of growing edible plants (such as fruit and vegetables) and other products. It is opposite to organic growing methods which attempt to produce without synthetic chemicals (fertilisers, pesticides, antibiotics, hormones) or genetically modified organisms. Conventionally grown products, meanwhile, often use fertilisers and pesticides which allow for higher yield, out of season growth, greater resistance, greater longevity and a generally greater mass.
What are the risks for environment from genetically modified food?
While some say there are no effects of genetically modified crops on the environment, others believe the following:Crops modified to be resistant to herbicides, such as Round-up, may be causing greater resistance to the herbicide in weeds than occurs when non-GMO crops are grown, either due to the genetic modification being transferred to the weeds or through more pesticides being used.Genetic modification involves taking a gene from one species (such as a bacteria) and inserting it into another species (such as corn or soybeans). In nature, genetic changes occur within species, though in rare occasions, they have been known to occur between similar species. It is not actually known what effects the changes created between species will have on the environment, though some believe this type of breeding could open the door to the modification being passed between species in the environment.Since weeds are becoming resistant to herbicides used on current GMO crops, crops resistant to other types of herbicides are being developed, which leads to greater pollution of the environment.Crops genetically modified to produce a chemical that kills insects when eaten, though claims are made that they only kill targeted insects, may be causing the deaths of non-targeted insects like butterflies and bees.Ultimately, risks to the environment from GMO crops is not known. Genetically modified crops have introduced new variations to genes that would not normally occur in nature. We can only observe changes that may be occurring as a result, and guess at what changes to the environment will ultimately occur.
Why some animals have good endurance while anothers have the ability to move very quickly but for a very short or time?
Why some animals have evolved to be faster, while others have more endurance I don't know.---- Genetically, this is determined by a difference in muscle fiber composition.Basically there are two types of muscle fiber:Type I (or slow-twitch) allow for low levels of exertion in which the muscles are used at well below their maximal contraction strength for long periods of time.Type II (or fast-twitch) allow for short bursts of higher intensity contractions at a much greater percentage of their maximum contraction strength.So animals with a greater percentage of type I will have more endurance, while animals with a greater percentage of type II will be faster.
What do people think of genetically modified food?
Some people believe that GM0 foods are safe and necessary to feed the world. Others believe they are harmful, if not dangerous, to the environment and human and animal health. Still others believe there may be a dark agenda behind them.
What are the advantages and disadvantages of frankenfood?
Modifying food crops through genetic methods results in products with remarkable advantages like longer shelf life and resistance to pests when they are grown in the field. The primary motive for genetically engineering food crops is to increase yield. Since this process involves the insertion of foreign genes into wild type crop genomes, the uninformed people in the press have coined the term 'frankenfoods' to describe genetically modified crops. Here are some of the advantages of genetically modified foods: * Greater yield (wheat, rice, tobacco) * Pest resistance (corn) * Longer shelf life (vegetables) * slow ripening of fruits (apples, oranges) * Foods supplemented with essential dietary components - beta carotene rice (golden rice) * Better taste retention (flavr-saver tomatos) and some of the disadvantages: * public acceptance - people approach these genetically engineered foods with a lot of scepticism. Although the scientists who created them are confident about their safety.
