Answer: B) The number of electron in its valence shell.
Explanation:
Outermost electrons of the atoms which can participate in the chemical bond formation is known as valence electrons.
Atoms either transfer or share its valence electrons during chemical bond formation. Atoms transfer or share electrons to attain octet or in other words stability.
Generally, 8 electrons are required in their outermost shell or valence shell in order to attain stability. This rule is known as octet rule.
For example, general electronic configuration of sodium belonging to group 1 is 1s2 2s2 2p6 3s1.
No. of valence electrons in Na = 1
by loosing 1 electron, its outer shell electronic configuration become = 1s2 2s2 2p6 (Octet)
Hence, sodium and other group 1 elements are very reactive.
Similarly, halogens (ns2 np5) by gaining 1 electron attain octet (ns2 np6). Hence halogens are also very reactive.
Carbon atom belonging to group 14 has 4 valence electrons (ns2 np2) and share all 4 valence electrons to attain octet and hence reactive.
Nobel gases have octet in their outermost shell (ns2 np6), hence they are most nonreactive element.
Answer:
Treatments like endoscopic therapy and medications like propranolol aim to reduce the pressure in varices, lowering the risk of bleeding.
Explanation:
Portal hypertension is high pressure in the portal vein. The medications and various treatments try to reduce that pressure.
Answer:
Medical malpractice is sometimes a broad category of several types of actions. In some situations, healthcare fraud is considered to be medical malpractice. Usually these crimes involve actions of medical professionals using medical procedures to fill their pockets. Thousands of medical procedures each year are performed by various healthcare providers that are unnecessary and often not related to the issue the patient has. These unneeded procedures are often performed because insurance companies, Medicare, Medicaid and even private insurance businesses pay the healthcare facility for longer visits and extra care for patients who need treatment that helps prevent surgery complications. A new study published in the Chicago Tribune explained an analysis of records for over 34,000 patients with surgical procedures in 2010 at one of twelve specific hospitals run by Texas Health Resources. Of these, over 1,800 had at least one complication that was preventable. These complications led to a quadrupled length of stay at the facility to up to fourteen days increasing the revenue of the hospital to a little over $30,000 average additional costs.
For some physicians, these unneeded procedures were due to improper or inadequate training. These situations may not be considered fraud. However, if the surgical procedures were due to the fraudulent circumstances the Chicago Tribune discovered, both the healthcare facility and any participating physicians may be guilty of fraud. Criminal charges would be added to civil medical malpractice liable actions.

Answer:
one of the spleen's major jobs is filter the blood.
Explanation:
One of the spleen’s main jobs is to filter your blood. It affects the number of red blood cells that carry oxygen throughout your body, and the number of platelets, which are cells that help your blood to clot. It does this by breaking down and removing cells that are abnormal, old, or damaged.
The spleen also stores red blood cells, platelets, and infection-fighting white blood cells.
The spleen plays an important role in your immune system response. When it detects bacteria, viruses, or other germs in your blood, it produces white blood cells, called lymphocytes, to fight off these infections.
B should be correct if anything just look it up
