The correct answer would be: dependence on nonrenewable resources.
A nonrenewable resources are resources that cannot be readily replaced by natural means, such as fossil fuels (oil, natural gas). The use of these resources is not sustainable because their formation takes billions of years. The whole world is dependent on these non-renewable sources but they are becoming more scarce daily.
Answer:
The answers are Fluorine and Francium.
Explanation:
Fluorine has the highest affinity for electrons while Francium has the lowest affinity for electrons. This can be measured by the electronegativity of each one, where Fluorine is the most electronegative element. This can also be seen by the accommodation of elements in the periodic table.
Answer:
each sense ( eyes ears nose mouth ect.) sends electrical pules through the nerves or "messages" to the brain. which then processes it and turns it into information so that you can understand what you are seeing, hearing, tasting ect

Well, an endoskeleton is an internal skeleton, like humans have.
Pro: Bones do not get broke as easily, since they are inside of the body. Bones that break also heal more quickly in an endoskeleton, since they have tissue and blood surrounding it and transferring nutrients.
Con: The flesh can get easily damaged. There is no shedding with endoskeletons, so a new skeleton cannot be grown in the event of an injury.
