Answer:
c. Vitamin B12 deficiency
Explanation:
Vitamin B12 deficiency is the cause of many diseases, from anemia to thrombosis. This deficiency is not common in the US, however, it is easily caused by inadequate gastric acid secretion secondary to gastric resection, use of drugs that suppress gastric acid, or gastric infection by Helicobacter pylori.
Vitamin B12 is essential for red blood cell formation, integrity and maturation. In their absence, they increase in volume. In the bone marrow - where they are produced - the number of cells increases so much that the appearance simulates that of leukemias.
It is a necessary vitamin for the development and maintenance of nervous system functions. Without it, the myelin that covers the nerves (as the protective cap does with the electrical wires) suffers wear that is called demyelination, a process that occurs in both peripheral nerve neurons and those in the white matter of the brain.
The main source of B12 is in animal foods. But to absorb it, the digestive tract depends on intrinsic factors present in a special group of stomach cells (parietal cells) and receptors located in the ileum.
Answer:
Artificial Passive Immunity
Explanation:
Passive immunity is the type of immunity an individual can develop when the individual receives antibodies produced by another individual or elsewhere, rather than being produced by the individual’s immune system, against a particular disease. This type of immunity provides immediate protection but does not last for long.
Passive immunity can be achieved naturally by an individual when antibodies are passed through breast milk or placenta of the mother at birth to the individual.
Artificially, passive immunity can be achieved when an individual receives antibodies produced from an external source rather than from the individual’s body immune system, usually through an injection in the form of “gamma globulin”.

You must tell her that a Private Fee-for-Service (PFFS) plan may affect her access to services to vary the provider's pay rates solely based on the provider's specialty or location or to increase usage of certain preventive or sorting
<h3>What is the Private Fee-For-Service (PFFS) plan?</h3>
A Private Fee-For-Service (PFFS) plan is a Medicare Advantage (MA) health plan offered by a state-licensed risk entity that has an annual contract with the Centers for Medicare & Medicaid Services (CMS) to provide all your Medicare benefits, in addition to any additional benefits the company chooses to provide, to beneficiaries. The PFFS plan:
• Pays providers on a fee-for-service basis without putting providers at financial risk
• Vary provider payment rates solely based on provider specialty or location or to increase utilization of certain preventive or screening services
• Does not restrict participants' choice among providers legally authorized to provide services and accept the plan's payment terms and
• Does not allow the use of prior authorization or notification.
With this information, we can conclude that you must tell her that a Private Fee-for-Service (PFFS) plan may affect her access to services to vary the provider's pay rates solely based on the provider's specialty or location or to increase usage of certain preventive or sorting
