The answer is water. it is found in our bodies (sorry the professor said its technically closest to oxygen because oxygen is most of our body)
YES THWY ARE correct goo hob
Hello,
Most organisms emit A. Infrared Waves because we produce heat from our body which shows up as Infrared.
Enjoy :)
Answer:
A & C
Explanation:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
YES - A) You must have variation in the population, typically in the terms of "fitness" or having admirable/sucessful traits that make them more likely to reproduce and ensure their own offspring are fit too.
NO - B) It is sexual (not asexual) reproduction that uses natural selection for their offspring. Although some asexual organisms use natural selection, it is ALWAYS used if possible with natural selection to ensure the fitness of characteristics is passed down.
YES - C) Competition is necessary for natural selection to occur. When those who are more physically fit compete, they are more likely to live against their opponent and therefore pass on the trait of fitness.
NO - D) Although resources are necessary, large amounts are not as it does not lead to fighting over them (scarcity) bringing us back to the need for competition above.
Hope this helped!
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").
