Darwin proposed an idea that all species change over time because those that are best adapted to their environments are able to survive and pass on their traits to their offspring. This became known as Darwin's theory of evolution. This historic insight was described based on his observations of the inhabitants of the Galapagos Islands.
choices are:
Mike is right because the atomic mass of lithium is 6. There are 3 protons and 3 electrons in the atom. 3+3=6
Joan is right because the atomic number of carbon is 6. There are 3 protons and 3 electrons in the atom. The atomic number shows the number of protons plus the number of electrons. 3+3=6
Joan is correct because carbon is a neutral atom. There are the same number of protons and electrons in the atom pictured.
Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
Li has atomic no. 3 and mass 7. so the correct ans is Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.

The correct answer is "headache and confusion".
The human body has several mechanisms of action in order to protect critical organs from excess blood pressure and flow. When these mechanisms are not successful in protecting the capillaries of the brain, the patient could suffer from cerebral edema (swelling of the brain) and papilledema (swelling of the optic nerve). These conditions could cause severe headache, confusion, motor and sensory problems and visual disturbances.
