Answer:
The correct answer would be the slide should be almost in focus when changing to higher magnifications.
A parfocal lens is a type of lens which stays in focus when focal length or magnification is changed.
Parfocal microscopes are those in which objectives remain in focus even when magnification is changed for example, when it is switched from 10x to 40x, the object or slide remains at the focus.
Deletions are mutations<span> in which a section of DNA is lost, or deleted. Since protein-coding DNA is divided into codons </span>three<span> bases long, insertions and deletions can alter a gene so that its message is no longer correctly parsed. These changes are called frameshifts.</span>
The nurse will explain to the client is
the catheterization will visualize the disease process in the coronary arteries.
A cardiac catheterization delivers information on how well a heart
works, recognizes problems and allows for procedures to open blocked
arteries.
For example, during cardiac catheterization your doctor may:
<span>
Gather
up samples of blood to measure the oxygen content in the four chambers of
your heart.
<span>Take X-rays using
contrast dye injected over the catheter to look for narrowed or blocked
coronary arteries. This is known as coronary arteriography or coronary
angiography.
</span>
Assess
the ability of the pumping chambers to contract.
Look
for deficiencies in the valves or chambers of your heart.
Execute
a percutaneous coronary intervention (PCI) such as coronary
angioplasty with stenting to open up narrowed or blocked segments of
a coronary artery.
Check
the compression in the four chambers of your heart.
Remove
a small piece of heart tissue to examine under a microscope (biopsy).</span>
