-Drought
-Herbicides
-Insect herbivory
-Low nutrient soil
-Disease

Answer 1

The most common conditions/substances for which plants have been genetically modified to resist are Herbicides, Insect herbivory, and Disease. While drought resistance and low nutrient soil tolerance exist, they are currently less common in comparison. The correct answer is option 2,3,5.

Step-by-step explanation:

Plants have been genetically modified (GM) for several reasons, to enhance certain desirable traits such as yield, nutritional content, and resistance to environmental stresses. Among the modifications, there are a few conditions and substances to which plants have been commonly engineered to resist. These include:

• Herbicides - GM crops such as soybeans, corn, and cotton have been engineered to tolerate specific herbicides, allowing farmers to control weeds without damaging their crops.
• Insect herbivory - Plants like BT corn have been modified to express a toxin originally found in a bacterium called Bacillus thuringiensis, which is lethal to certain insects when ingested.
• Disease - Modifications have also been made to make plants resistant to viral, bacterial, or fungal pathogens, reducing crop loss and reliance on chemical treatments.

While genetic modifications for drought resistance and low nutrient soil tolerance exist, they are less common compared to herbicide, insect, and disease resistance. In conclusion, the most common conditions/substances for which plants have been genetically modified to resist are Herbicides, Insect herbivory, and Disease.
