The answer is the first one: Staphylococcus aureus.

Explanation for each option:

  1. Staphylococcus aureus: This bacterium is a major source of human infections and is well-known for its antibiotic-resistant strains, such as Methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a significant public health concern due to its resistance to many commonly used antibiotics.

  2. Staphylococcus epidermidis: While this bacterium can cause infections, especially in immunocompromised individuals or those with implanted medical devices, it is not as commonly associated with antibiotic resistance as Staphylococcus aureus.

  3. Streptococcus pyogenes: This bacterium causes a variety of infections, including strep throat and skin infections. Although there are some concerns about antibiotic resistance, it is not as prominent as the resistance seen in Staphylococcus aureus.

  4. Mycobacterium leprae: This bacterium causes leprosy. While it is a significant pathogen, it is not typically associated with widespread antibiotic resistance in the same way as Staphylococcus aureus.

Summary: Staphylococcus aureus is the major source of human infections known to be antibiotic-resistant, making it a significant public health concern.

In a genetics experiment on peas, one sample of offspring contained 432 green peas and 34 yellow peas. Based on those results, estimate the probability of getting an offspring pea that is green. Is the result reasonably close to the value of 3/4 that was expected? The probability of getting a green pea is approximately 0.927. (Type an integer or decimal rounded to three decimal places as needed.) Is this probability reasonably close to 3/4 ? Choose the correct answer below. A. No, it is not reasonably close. B. Yes, it is reasonably close.
