Answer:
Petroleum
Explanation:
Like all fossil fuels, petroleum is a nonrenewable energy resource. This means that it is a resource that cannot be replaced as quickly as humans use up existing supplies. Humans face a problem because once petroleum reserves begin to run out, there won't be enough fuel to power all the automobiles in the world.
Hello!
In order to find the correct answer, you need to find a hypothesis that cannot be proven wrong. Out of the options in the prompt, all but one can indeed be proven wrong. The correct answer is A because there is no way anyone can tell if there is a teacup orbiting the Milky Way galaxy or not. We know that it can be proven wrong there is no life on Mars, the human species started in Africa and that humans cannot live without a certain amino acid. The only thing that really can’t be proven wrong (that is quite stupid) is the one about a teacup.
Upon studying the theory of falsifiability, I came across an example of a person who claimed they had invisible unicorns in their digestive tract. We know that this (incredibly dumb) example cannot be proven wrong because, well, there is no way to actually know what’s in someone.
It’s mechanical because it’s fs not weathering
Answer:
b. prevent the heart from filling properly with blood
Explanation:
The pericardial cavity is the cavity present between the visceral pericardium and the parietal pericardium. It is filled with a fluid called pericardial fluid. In cardiac tamponade, there is an accumulation of excess of the fluid in the pericardial cavity.
The fluid builds up the pressure which in turn compresses the heart. Ventricles of the compressed hearts are not completely filled with blood resulting in reduced cardiac output. Similarly, the return of blood to the heart atria via veins is also reduced in the compressed heart.
