In healthcare amenities like in nursing homes and hospitals, MRSA (methicillin-resistant Staphylococcus aureus) infection is one of the most common concern. These infections generally involve the skin, and the individuals who are healthy can also get infected with the condition.
In order to prevent MRSA infection, doctors, nurses, and other healthcare workers need to follow certain steps. These are as follows:
1. Carefully clean the hospital rooms and medical apparatuses.
2. Clean their hands with soap and water, or with an alcohol-based hand sanitizer prior and post caring for a patient.
3. Test some patients to observe if they exhibit MRSA on their skin. This is done by swabbing a cotton tip in the nostril or on the skin of the patient.
4. Use contact precautions, while caring for the patients with MRSA.
Answer:
The correct answer will be- Option-4
Explanation:
Carl Woese is well known for dividing the five-kingdom system into three domains: Archaebacteria (ancient bacteria), Eubacteria and the Eukaryotes on the basis of the studies of the ribosomal RNA.
Since the three-domain system does not include the cyanobacteria group which includes the photosynthetic bacteria therefore, the Cyanobacteria is the correct answer.
Thus, Option-4 is the correct answer.
Answer:
a. facilitated diffusion
Explanation:
Instead, cells assist glucose diffusion through facilitated diffusion and two types of active transport.
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
