Persistent chlorinated hydrocarbon pesticides persist in the environment and accumulate in the foods chain causing harmful effects on the environment including posing a threat to humans health in the long term. Nonpersistent organophosphate pesticides are more toxic than the former but degrade after a short life span. Therefore they cause immediate harm in case one is in contact with them.
The fact that they do not accumulate in the environment, they are more favourable than chlorinated hydrocarbon pesticides. Chlorinated hydrocarbon pesticides will affect several generations due to their accumulation in the environment. However they don't need to be re-applied hence are less expensive
Answer:
Desventajas
*Pueden "contaminar" otras plantas.
*Pueden llegar a ser cancerígenas en el caso de ser consumidos por sujetos proclive o en un estado inmunológico deficiente.
*Puede producir alergias, debido al material genético transferido, a la formacion inesperada de un alérgeno o a la falta de información sobre proteína que codifica el gen insertado.
The correct answer is true
FDA issued a black box warning about the use of Tacrolimus and the development of cancer in animals and humans.
Tacrolimus is a topical drug used for dematitis. It is a chronic condition which the skin becomes inflammed, red, itchy. The inflammation is caused by the activation of immune function of the patient. Tacrolimus is used as topical agent to suppress the function of immune system and inflammation by inhibition of calcineurin. This is an enzyme needed for T cell production. T cells plays a big factor in the activation of immune system.
Answer:
Active transporters or ion pumps are transporters that convert energy from various sources—including adenosine triphosphate (ATP), sunlight, and other redox reactions—to potential energy by pumping an ion up its concentration gradient.
