Identify the incorrect statement:
1. B. thuringiensis forms protein crystals during a particular phase of its growth.
2. The protein crystals contain a toxic insecticidal protein.
3.
Once an insect ingests the inactive toxin, it is converted into an active form of toxin due to the acidic pH of the gut.
4. The activated toxin binds to the surface of midgut epithelial cells and creates pores that cause cell swelling and lysis and eventually cause the death of the insect.
