Bt cotton is_______resistant.

Explanation

**Step-by-Step Solution:**

1. **Understanding Bt Cotton**: Bt cotton is a genetically modified organism (GMO) that has been engineered to express a specific protein from the bacterium *Bacillus thuringiensis* (Bt). This protein is toxic to certain insects.

2. **Insect Resistance**: The primary purpose of Bt cotton is to provide resistance against specific pests, particularly the cotton bollworm, which can cause significant damage to cotton crops.

3. **Mechanism of Action**: When insects feed on Bt cotton, they ingest the Bt protein. This protein disrupts their digestive system, ultimately leading to the death of the insect. This mechanism allows the cotton plant to protect itself from pest infestations.
