Answer: True

Explanation: Like all living things, prokaryotes need energy and carbon. They get energy from inorganic chemical compounds.

Chemoautotrophs are organism that utilizes inorganic molecules to supply energy for the organism, and use carbon dioxide as a carbon source. Chemoautotrophs are mostly prokaryotes that break down hydrogen sulfide and ammonia.

Most Eukaryotes cannot utilize these inorganic molecules as energy source.

Write down the clinical findings which are least suggestive of left-sided heart failure?
Arada [10]

Answer:

Adverse heart conditions do not occur in isolation. It is usually accompanied by other risk factors, like coronary artery dysfunction, diabetes, high blood pressure, etc.    

In addition to the above, the following factors are indicative of left-sided heart failure:

  • Shortness of breath caused by the collection of fluid in the lungs. Shortness of breath usually becomes pronounced upon physical exertion
  • An increase in the girth of the torso (mainly the abdomen) due to ascites which is the buildup of fluid in the abdomen.
  • engorged scrotum (in males of course)

Explanation:

Left-Sided Heart Failure is simply the inability of the heart to pump oxygen-rich blood into the body.

Blood filled with oxygen is moved from the lungs to the atrium on the left and then to the left ventricle. The blood is then pumped from the ventricle on the left to other parts of the body by a contracting and relaxing action. Left-sided heart failure can be classified into two:

  1. Systolic Failure and
  2. Diastolic Failure

1. Systolic Dysfunction: When the left ventricle can no longer shrink properly, the pressure with which the heart can pump enough blood into circulation is reduced.

2. Diastolic Dysfunction: This occurs when the left ventricle can no longer relax as it ought to due to the hardening of the muscle.

Which part of the electrocardiogram would most be affected by abnormally slow repolarization of ventricles?
Burka [1]

The electrocardiogram most be affected by abnormally slow repolarization of ventricles SA node.

Repolarization occurs because of an growth in potassium permeability. on the SA node, potassium permeability may be further enhanced through vagal stimulation. This has the effect of hyperpolarizing the cellular and decreasing the charge.

The T wave represents ventricular repolarization. The T wave reveals a high quality deflection. The motive for that is that the ultimate cells to depolarize inside the ventricles are the primary to repolarize.

The SA node generates an electrical sign that causes the top coronary heart chambers to settlement. The signal then passes thru the AV  node to the decrease heart chambers, causing them to contract, or pump. The SA node is considered the pacemaker of the coronary heart.
