Juliette [100K]

The generic name of poisonous chemicals, very often used in commercial agriculture that are used to kill organisms that either reduce the yield of crops or are harmful to animals are pesticides.

Pesticides are the chemicals used to kill the pests affecting the growth and yield of the crops. Pesticide is a broad term covering various small terms according to the pest being killed. For example insecticide, nematicide, avicide, rodenticide, bactericide, etc. Some chemicals used as pesticides are boric acid, Acephate, Deet, Propoxur, glyphosate, etc.

Commercial agriculture means growing of crops so as to sell them in the market to be utilized by the wide population of any area. Any crop can be grown at the commercial level. These crops do not reach the customers directly by the farmers, instead they are sold to whole-sellers first.

Describe the mutation in a plant that could have a negative outcome for the organism
iris [78.8K]
A mutation in a plant that could cause negative outcomes could be the plant has less leaves, or isn't hardy enough, like other plants. It would die. A plant from an area like Chernobyl, that has been affected by radiation could poison other animals, or pass that gene along, and ultimately kill that strand of plant.

Deffense [45]

Answer:

Its false  

Amphicoelias altus (from the gr. "Hollow character on both high sides") is the only known species of the extinct genus. Titoniense, in what is now North America. Amphicoelias is present in stratigraphic zone 6 of the Morrison Formation

It was also similar in size to Diplodocus, about 25 meters long. Although most scientists have used this data to distinguish Amphicoelias and Diplodocus as separate genera, at least one has suggested that Amphicoelias is probably the largest synonym for Diplodocus.3 Amphicoelias altus, was named by paleontologist Edward Drinker Cope in December of 1877, although it was not published until 1878, for an incomplete skeleton consisting of two vertebrae, a pubis, the hip, and a femur, bone of the upper leg.4 Cope also named a second species, A. fragillimus
