For over a decade, farmers in the u. s. have been planting genetically modified crops. an example of one of these crops is corn that is resistant to weed-killer. this makes it so that no corn is lost due to contact with herbicide meant to kill weeds. while this is seen by many as a positive development, others see it as a cause for concern. what is one possible negative side effect of planting genetically modified corn? a) genetically modified corn, as well as other plants, is unnatural. b) corn will replace wheat and other crops as our main source of carbohydrates. c) plants with modified genomes may have a predictable impact on the environment. d) plants with modified genomes may have an unforeseen impact on the environment.

The correct answer is option D.

The U.S have been planting genetically modified crops. These crops have benefits more than normal crops but there could be some possible negative sides of these crops.

There could be longer term problems associated with the production of the genetically modified crops and these negative effects can be non predictable.

There are many predictable reasons associated with the use of genetically modified crops that can be cured but some of the results might have unforeseen impact on the environment.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
