There are choices for this question namely:
a) "Exhale forcefully while the chest tube is being removed."
b) "While the chest tube is being removed, raise your arms above your head."
c) "During the removal of the chest tube, do not move because it will make the removal more painful."
<span>d) "When the tube is being removed, take a deep breath, exhale, and bear down."
The correct answer is "when the tube is being removed, take a deep breath, exhale, and bear down". This is called a Valsalva maneuver and this functions to prevent the air from leaking back to the pleural space and eventually prevent pneumothorax. After which, a clean, air tight, dressing shall be applied to the wound.</span>

Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Answer:
Explanation:
Inside a cell, numerous organelles function to remove wastes. One of the key organelles involved in digestion and waste removal is the lysosome. Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
