Is influenza living and nonliving?
A virus is non living as according to the modified Cell Theory, cells are defined as the basic building blocks of life, while viruses are not made up of cells. In fact, a virus is nothing more than a protein capsid encapsulating genetic material (either DNA or RNA), hence a virus would more correctly be termed as an infectious particle.
Viruses are non-living.
Virus are living object because:
They possess genetic material DNAs or RNAs. They can reproduce and mutate. They react to stimuli such as radiation, chemicals and heat. They possess antigenic properties. They are capable to multiply with same genetic constituent.
Virus are non-living because:
They can be crystalize like non living material. They are inert like chemical outside the host. Cell wall and cell membranes are absent. Protoplasm is also absent. They do not have any functional anatomy. They can not multiply without host nuclear machinsery.
However, in order to be qualified to be a living organism, it must be able to show all of the characteristics of life, therefore viruses are not living.
Viruses are not considered non living because alone they cannot replicate, they need a host (another living cell) to replicate. They do not have cells. Biologically speaking they are non-living things.
What characteristics does an abnormal lymph node biopsy have?
Any abnormalities in the size, color, and consistency of the sample will be reported as an abnormal result. In addition, any change in the structure of the renal tubules, the presence of red blood cells, or abnormalities in the cells.
How long does it take for a biopsy report take to complete?
a while
[edit by Athena4299] That doesn't really answer the question... How long is "a while"?
What is the qualification to become a pathology assistant?
Most of the PA programs for pathology assistant students are masters degree programs that require you to have a bachelors degree in a science field. When you complete the two year masters program you will receive a masters of pathology and be eligible to take the national exam. But I have also seen a few schools that offer bachelors degree programs in PA and you do not need to get your masters, google "Pathology Assistant Accredited Programs" I'm strongly considering it myself.
What is the pathological process of Potts fracture?
Potts disease is secondary to an extra spinal infection and will usually involve more than 1 vertebra. Tuberculosis will likely spread from the vertebra to the disks.
Can I be put to sleep for a bone marrow biopsy?
You could be anesthetized for a bone marrow biopsy if you request it strongly enough. I believe in general that people are heavily sedated with strong local anesthetic prior to this procedure anyway since it is relatively painful.
What is the allowable neutrophil cell number in urine?
The normal value is zero, although some reference values may allow up to trace amounts in a free catch sample.
What is the pathophysiology of tracheotomy?
* Cook Blue Rhino single dilator kit * video bronchoscopy * Intubation Roll * Cricoid Hook * tracheostomy set
How do you increase Protein C?
I have a low protein in the blood result....would like to know what causes this, and how do I elevate the protein to what it should be. Thank you Ann
What does pathological fear mean?
Fear is a basic emotion that causes a person to either run away or become aggressive to defend against an attack. Pathological fear is a fear so severe and debilitating that it significantly interferes normal daily life functions. For instance, some people have a pathological fear of open spaces (commonly called agoraphobia) that can be so severe that they cannot leave their houses to check the mail box - the open space in the lawn is too much for them to handle.
A liver scan is usually ordered after blood studies and other imaging procedures have shown a liver abnormality. It is most often used to further evaluate masses or tumors. These may be benign growths in the liver, or cancer
What is intra articular pathology?
Intra-articular pathology would be disease of the articular cartilage and would encompass Arthritis, cartilage erosion, neoplasia and developmental disorders of cartilage and subarticular bone.
How is a lymph node biopsy done?
A liver biopsy can be performed a few different ways: a needle can be inserted through the skin, and take a sample of the liver; during abdominal surgery, a piece of the liver may be removed; through blood vessels, a sample of the liver may be taken. the live sample would then be taken to be studied under a microscope.
What is metabolically active lymph nodes?
No, looking for metabiolically active nodes in the mediastinum
What does duty of care mean in the pathology collectors workplace?
Duty of care is maintaining personal hygiene ,clean environment , safe , don't discriminate ,sterile equipment usage, if the patient is not feeling good after blood test don't let them go keep under your observation.
What is the name of a Circulatory system pathology?
The circulatory system, now generally referred to as the cardiovascular system, can be affected by a variety of diseases that can be broadly classified as infectious, inflammatory, degenerative or cancerous.
An example of an infectious disease of the cardiovascular system would be bacterial endocarditis. This is when a bacteria become attached to one or more valves of the heart and set up a localized infection.
An example of an inflammatory disease of the cardiovascular system would be athlerosclerosis. This is when inflammatory mediators cause the lining of the blood vessels to become "sticky", which allows cholesterol molecules to be deposited in the walls of the vessels. The cholesterol hardens the arteries, making them more likely to rupture or become blocked.
An example of a degenerative disease of the cardiovascular system would be endocardiosis. This is a chronic disease in which the valves of the heart slowly degenerate and become less competent at closing the openings between the heart chambers. Eventually this can lead to congestive heart failure if it becomes bad enough.
An example of a cancerous disease of the cardiovascular system would be hemangiosarcoma. This is a neoplasia that arises from the lining of the blood vessels and branches off from normal vessels to create very fragile pseudo-vessels. Unfortunately, one of the more common symptoms of this cancer is sudden death; thankfully in humans this cancer is relatively rare.
How does kidney failure affect the urinary system?
The kidneys are the starting point of the urinary system, the organ where urine (waste liquid materials) are filtered out of the blood stream. Dysfunctional or nonfunctional kidneys create abnormal urine, and usually an abnormal amount of abnormal urine. This can range from anuria (no urine) to polyuria (urinating multiple times a day) and from urinating basically straight water (clear, colorless, USG <1.003) to urinating pus, blood, serum, or some combination thereof.
There are several tests done for thyroid function. They require different tubes.
What the meaning of Pathology?
Pathology is from the ancient Greek words "pathos" and "logos". The current definition means "the study of disease, from initation to final outcome".
What is sentinel lymph node mapping and biopsy?
A new technique called sentinel lymph node mapping and biopsy often eliminates the need for removing some or all lymph nodes by testing the first lymph node for cancer.
Why is a complete autopsy performed including a toxicology report?
The toxicology report will test for the presence of poisons, medications, alcohol and illicit drugs. this is important in telling the cause of death and the circumstances surrounding the death. It can tell you if a person was high, drunk, or poisoned at the time of death.

Which subjects do you need to have to study forensic pathology?
it really doesnt matter what classes you take in high school. what matters is the track you take in college. but if you are in high school and your goal is to be a forensic pathologist, one would imagine that any type of science class would be enjoyed. take anatomy and physiology, medical science, chemistry, biology, and all the higher level science classes that are available.
