Hepatitis C is a virus that attacks the liver and can cause liver disease. Liver disease has been linked to a reduction in album
Rom4ik [11]

Answer:

a) Ribosomes

b) Please find the justification for the answer in (a) below.

Explanation:

According to this question, Hepatitis C is a virus that causes liver disease by attacking the liver. However, a REDUCTION IN ALBUMIN, which is a protein that regulates oncotic pressure of blood in humans- a process necessary for the regulation of fluids in vessels of the body and tissue repair, has been found to have to do with liver disease.

Since ALBUMIN is a protein produced by the liver, which when diseased causes a reduction to the blood-albumin level, the organelle in liver cells that is most likely being affected by hepatitis C is the RIBOSOME. This is because the RIBOSOME is the organelle/site for PROTEIN SYNTHESIS in any cell. Hence, the ribosome organelle of the liver cells are responsible for synthesis of Albumin protein.

Hence, a diseased liver due to attack by Hepatitis C virus means an attack on the RIBOSOMES of the liver cells producing the protein.

Why is it better to describe ion formation as a “transfer of electrons” rather than as “losing and gaining” electrons?
Nata [24]

Explanation:

This is because the atom that ’donate’ the electrons and the one that ‘accepts’ the electrons – to become ions – will share an electrostatic association and form an ionic bond. So in reality, the atoms are only transferring electrons between themselves  rather than “losing and gaining” electrons. When the ionic bonds are broken, such as in chemical reactions, the atoms go back to neutral (regain their electrons) and form new associations with other atoms to form new compounds.

It could be managed by nutritional support coupled with pharmacological treatment such as diuretics and regular insulin.

A thrombus (blood clot) in the first branch of the arch of the aorta would affect the flow of blood to the ________. A. left sid
seropon [69]

Answer:

C. right side of the head and neck and right upper arm

Explanation:

The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.

The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.

Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.
