Question

multiple choice 1point which of the following best describes genetic modification in agricultural biotechnology? natural evolution of crop species selective breeding of plants using chemicals to kill pests direct manipulation of an organisms dna to introduce desired traits multiple choice 1point what challenge does agricultural biotechnology face regarding ecosystem impact? soil temperature regulation difficulties caused by gmo crops water distribution system improvements needed for gmo crops cross - pollination with non - gmo crops that could cause risk to native crops farm equipment maintenance due to increased needs of gmo crops

Explanation:

1. Genetic modification in agricultural biotechnology is the direct manipulation of an organism's DNA to introduce desired traits. It is not natural evolution, selective - breeding (which is a more traditional method), or using chemicals to kill pests.
2. One of the ecosystem - related challenges of agricultural biotechnology is cross - pollination with non - GMO crops, which can pose a risk to native crops. Soil temperature regulation, water distribution system improvements, and farm equipment maintenance are more related to other aspects of crop cultivation rather than direct ecosystem impacts of genetic modification.

Answer:

1. Direct manipulation of an organism's DNA to introduce desired traits
2. Cross - pollination with non - GMO crops that could cause risk to native crops
