The methicillin-resistant form of the bacterium commonly known as staph was first identified in the 1970's in hospitals, but it has since spread across the world, showing up in day cares, schools and other public spaces. Today, 1.2 million MRSA infections occur in hospitals in the U.S. and invasive MRSA kills over 19,000 per year,However, In the past, penicillin was used to treat Staphylococcus aureus infections. Shortly after, S. aureus became resistant to penicillin. During the 1950s, derivatives of penicillin was discovered by pharmaceutical companies that could treat Staphylococcus aureus . The graph below depicts the Spread of Antibiotic-Resistant S. aureus Infections in the United States. Separate curves are shown for bacteria that caused infections in the hospital ("Hospital-Acquired") and in healthy people in the community ("Community-Acquired").

On average the metabolic energy a person generates is enough to produce one's own body weight of ATP everyday just to function and every second about 50 trillion cells consumes and regenerates 10 million molecules of ATP.
The magnitude of a star is an expression of a star’s C) brightness.
Answer:
They affect the cycle by adding more/extra carbon into the atmosphere.
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars, planes, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
Correct answer: D). Tides
The tidal force is generated by the combination of gravitational attraction between the earth, moon and the sun and the rotation of Earth-sun and the earth-moon system. The tides rise and fall on the ocean surfaces. The moon has a large effect on the generation of the tides than the Sun.
Thus, the correct answer would be option D.
