Arrange the events in the correct order to describe how the magnetic field forms around Earth.

1 answer:

6 0

The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.

The right answer is glutamate

Glutamate is a major excitatory neurotransmitter associated with learning and memory.

It is also associated with Alzheimer's disease whose first symptoms are felt in memory.

Most people unknowingly consume monosodium glutamate (MSG), a commonly used food additive.

An experiment was done on healthy patients, giving them 12 grams of glutamate. It was found that the experience led to headaches, nausea or jaw pain in 50-60% of cases.

It was also measured the level of glutamate contained in the muscles of patients with jaw problems. The tests concluded that the most painful muscles were those containing the highest levels of glutamate.

According to him, one of the keys to chronic pain could lie in the development of drugs that reduce the rate of glutamate.
