4) biotechnology has produce crops that are resistant to certain pests, crops that produce high yields, and more nitrogen-efficient crops. what is a negative impact that bioengineered plants may have on the environment? a) beneficial insects may be adversely affected. b) plants have an increased resistance to insect pests. c) there is an increased need for inorganic fertilizers. d) genetically engineered plants may have a longer shelf life.

Option a

Explanation:

Biotechnology is the branch which deals with the most advanced techniques which is required to make the life easy.

One of the most important application is Genetically modified crops. Genetically modified crops are pest resistant and have many advantages.

There are few disadvantages one of them is beneficial insects are also adversely affected. There are many useful insects that helps in pollination and    they are also killed because of pest resistant plant.

hence the correct answer is option A

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
