In the end, the data can be used to estimate the population size and population density
Staphylococcus aureus is a gram-positive bacteria that cause a wide variety of clinical diseases. Infections caused by this pathogen are common both in community-acquired and hospital-acquired settings. The treatment remains challenging due to the emergence of multi-drug resistant strains such as MRSA (Methicillin-Resistant Staphylococcus aureus). S. aureus does not normally cause infection on healthy skin, however, if it is allowed to enter the internal tissues or bloodstream, these bacteria may cause a variety of potentially serious infections. This activity describes the evaluation and treatment of Staphylococcus infections and reviews the role of the interprofessional team in managing patients with these diseases.

Having a platelet count of 60,000/mirol is below the normal count of 150,000 which is called thrombocytopenia. With this low platelet count, our skin which is part of the integumentary system will show signs of Petechiae. Petechiae are formed and seen on the skin when capillaries underneath leaks blood due to low platelet count. Petechiae is commonly found on a person suffering from Dengue Hemorrhagic fever Disease where platelet count decreases.
Answer:
<em><u>Osmosis and facilitated diffusion</u></em> are two forms of passive transport that are integral to cellular transport mechanisms.
Explanation:
Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.
Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.
Across plasma membranes as a form of passive transport in cells, substances move via:
- osmosis - water molecules readily pass through the membrane; the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradient
- facilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.
