Question

1. which of the following is a potential negative effect of genetically modified organisms (gmos)?

a. gmos always require less water and fertilizer than traditional crops
b. gmos guarantee higher profits for every farmer in all regions.
c. gmos make crops completely immune to any pest or disease.
d. gmos may cross - pollinate with wild plants, affecting natural ecosystems and may cause cancer.

Explanation:

• Option A: GMOs do not always require less water and fertilizer. Their water and fertilizer needs depend on the specific modification and environmental conditions.
• Option B: GMOs cannot guarantee higher profits for every farmer in all regions. Profitability is influenced by market prices, production costs, and local farming conditions.
• Option C: GMOs are not completely immune to any pest or disease. Pests and diseases can evolve, and there may be limitations in the genetic modifications.
• Option D: GMOs have the potential to cross - pollinate with wild plants. This can lead to the spread of modified genes in natural ecosystems, which may have unforeseen ecological consequences. For example, it could affect the genetic diversity of wild plant populations and disrupt ecological balances.

Answer:

D. GMOs may cross - pollinate with wild plants, affecting natural ecosystems and may cause cancer.
