Green bananas are not poisonous, but they may cause digestive discomfort for some people. Green bananas contain resistant starch, which can be harder for the body to digest and may cause bloating or gas. As the bananas ripen and turn yellow, the resistant starch is converted into more easily digestible sugars, making them easier on the stomach. Therefore, it is safe to eat green bananas, but some individuals may want to wait until they ripen for easier digestion. **

No, bananas cannot whiten teeth. While bananas do contain some natural compounds that may contribute to oral health, such as potassium and magnesium, they do not have the ability to whiten teeth. The best way to whiten teeth is through professional dental treatments or over-the-counter whitening products that contain peroxide. **

Yes, electric guitars are powered by electricity. They require an amplifier to convert the electronic signal from the guitar's pickups into sound, and this amplifier is powered by electricity. Additionally, the guitar's pickups themselves rely on the electromagnetic properties of the strings to generate an electrical signal, which is then amplified and converted into sound. Therefore, without electricity, an electric guitar would not be able to produce sound. **

No, it is not possible to get drunk by eating bananas. Bananas do not contain any significant amount of alcohol. While bananas do contain a small amount of alcohol, it is not enough to cause intoxication. In order to get drunk, one would need to consume a much larger quantity of alcohol from other sources. **

Bananas are typically imported by ship rather than airplane. This is because shipping by sea is a more cost-effective and efficient method for transporting large quantities of bananas from tropical growing regions to other parts of the world. Additionally, bananas have a longer shelf life and are less perishable compared to other fruits, making them well-suited for transportation by sea. **

It is not necessary to watch Minions 1 before watching Minions 2 as the movies are standalone stories that do not require prior knowledge of the first film. However, watching Minions 1 may provide some background information on the characters and their relationships, which could enhance your understanding and enjoyment of Minions 2. Ultimately, it is up to personal preference whether you choose to watch the first movie before the second. **

A helicopter is powered by kerosene through its turbine engine. The kerosene is burned in the engine, which heats and expands the air inside the engine. This hot, high-pressure air is then forced through a series of turbine blades, causing them to spin rapidly. The spinning turbine blades are connected to the helicopter's main rotor shaft, which in turn rotates the helicopter's rotor blades and generates lift for flight. **

While lightning does produce a significant amount of energy, it is not a reliable or practical source for powering power grids. Lightning strikes are unpredictable and infrequent, making it difficult to harness and store the energy for consistent use. Additionally, the high voltage and short duration of lightning strikes make it challenging to capture and convert the energy into a form that can be used to power a grid. Therefore, while lightning may be a fascinating natural phenomenon, it is not a feasible source for powering power grids. **
