Cestoda are ectoparasite or endoparasite?

Cestoda are endoparasites, which means they live inside their host's body, particularly in the digestive system. They have specialized adaptations for this lifestyle, such as their flat, ribbon-like body structure and hooks or suckers for attachment within the host's intestine.

What conditions do you see single stranded DNA?

Single stranded DNA can form during processes like DNA replication, repair, or transcription. Conditions such as denaturation, where high temperature or extreme pH disrupt the hydrogen bonds holding the DNA strands together, can also lead to the formation of single stranded DNA. Additionally, viruses like ssDNA phages contain single stranded DNA.

What are tumor cells monoclonal kappa light chain positive?

These are tumor cells that arose from a single lymphocyte or plasma cell. The kappa light chain is a piece of the structure of an antibody; monoclonal means "single type". Therefore, these are tumor cells that all produce the same antibody structure, which indicates they are all derived from a single tumor cell that originally made this antibody structure.

How do you multiply yeast?

To multiply yeast, dissolve it in warm water along with sugar and let it sit for several minutes until it becomes frothy. This indicates that the yeast is active and multiplying. You can then use this mixture as a starter for your bread or other baked goods.

What are the disease of smooth ER?

Diseases of the smooth endoplasmic reticulum (ER) can include conditions like familial hypercholesterolemia, fatty liver disease, and drug-induced liver injury. These diseases are often associated with disruptions in lipid metabolism and drug detoxification processes within the smooth ER.

What is the study of chemical pathology?

Chemical pathology, also known as clinical biochemistry or clinical chemistry, is a branch of diagnostic medicine that involves the analysis of bodily fluids to diagnose and monitor disease. It focuses on the analysis of blood, urine, and other body fluids to assess biochemical processes and identify abnormalities that could indicate an underlying health condition.

Is plasmodium a pathogen or parasite?

plasmodium in the phylum sporozoa is called a parasite b/c it surrounds and engulfs its food

Why did the cat laugh?

Cats don't laugh in the same way humans do. Their vocalizations and expressions are typically related to communication, stress, or other emotions. If a cat makes a noise that sounds like laughing, it could be a sign of contentment or communication, but it's not actual laughter.

What is the procedure called to remove and destroy worn out blood cells?

Blood cells automatically die after 100-120 days for red blood cells and in a few days for white blood cells. They remain in the blood stream until they are detected by macrophages which are cells that discover and essentially eat dead cell. This process involves them surrounding the cells with a special coating that disallows them from re entering the blood stream. They are then eventually eliminated macrophages and all through the digestive system or kidneys. In fact a large percentage of human waste is made up of our bodies dead cells, including blood cells and other toxins.

How you can detect pathogen?

Pathogenic bacteria are those which cause disease. You can identify a link between a bacterium and a disease by isolating the bacterium in a statistically significant number of occurances of the disease. Proving the link is causative is more difficult, but could be done with a cohort study or in vivo experimentation. Probably the most well documented case in recent years is the proving of Helicobacter pylori as a causative agent of stomach ulcers.

What active transport system uses the most ATP?

The sodium-potassium pump, also known as the sodium-potassium ATPase, uses the most ATP during active transport. This pump hydrolyzes one molecule of ATP to move three sodium ions out of the cell and two potassium ions into the cell, against their respective concentration gradients.

What happen when a sample is aspirated into the flame?

When a sample is aspirated into the flame in atomic absorption spectroscopy, the solvent evaporates, leaving the atoms in the sample in a gaseous state. These atoms are then heated in the flame, causing them to reach an excited state. As they return to their ground state, they emit light at characteristic wavelengths that are detected by the instrument to determine the concentration of the element in the sample.

What is no adnexal pathology seen?

The phrase 'no adnexal pathology seen' means that the pathologist looked through the tissues surrounding the abnormal area but didn't see anything odd or unusual. "Adnexal" means "surrounding or supporting tissues".

Does all radioactive tracers detect pathology in every body system?

No, radioactive tracers are often specific to certain organs or tissues within the body. Different tracers are used to detect pathology in different body systems based on their biological properties and distribution in the body. It is important to select the appropriate tracer for the specific pathology being investigated.

How does nucleic acid sequencing help in molecular diagnosis?

To really understand this process, consider the idea that nucleic acid combinations are like keys, and diagnoses are like locks. When you arrange the different acids (A, C, T, U), you are essentially creating a new key. This tells the body that THAT key will fit in THIS lock, meaning that the diagnosis will then fit the conditions of the lock. The sequences match up to the conditions of the diagnosis.

What is the protection of natural habitats and wildlife called?

The protection of natural habitats and wildlife is called conservation. Conservation efforts aim to preserve ecosystems, species, and biodiversity to ensure their continued survival for future generations.

What is the pathology of ehlers-danlos syndrome?

Ehlers-Danlos syndrome is a group of connective tissue disorders characterized by defects in collagen synthesis and structure. This results in hypermobility of joints, skin elasticity, and tissue fragility. It is typically caused by mutations in genes involved in collagen production.

Why to do serial dilution for WIDAL test?

Serial dilution in Widal test helps to determine the titer of antibodies in the patient's serum by observing the agglutination reaction with specific antigens. By diluting the serum sample in a stepwise manner, the titer at which agglutination occurs can be determined, providing valuable information about the presence and concentration of antibodies against Salmonella typhi and Paratyphi antigens in the blood.

How does a blood serum enzyme test diagnose myopathy?

A blood serum enzyme test can diagnose myopathy by measuring the levels of enzymes that leak into the bloodstream when muscle cells are damaged. Elevated levels of enzymes such as creatine kinase (CK) can indicate muscle damage, which is common in myopathy. By analyzing these enzyme levels, healthcare providers can assess the severity of muscle damage and monitor response to treatment.

What is the theory of The Pathology of Normalcy?

It is the belief that the self, is a correct state of being. When a self moves past this stage, into "self actualization" it realizes "we have a problem Houston!" And that whole self, sees its dilemna, no longer able to hide from it due to "fragmentation avoidance."

Normalcy is the collected level agreed on by societal member, as to how much fragmentation of self, is acceptable, in order to avoid the truth, that the self actualized self can see. We call this "society."

Also, when a self, fragments beyond the level most people can hide from the truth with, we call that "a state of disorder, or illness." And those who are normal, pity the mentally ill, hoping one day they can return to the normal state of fragmentation.

To the self actualized, this is quite hypocritical, if they are advanced enough in their path. To the transcended (beyond self) they believe those mentally ill selves realize that their is a problem, because they are not accepted by the fragmentation norm (society) and believe those ill people are more open to the truth, than the self righteous. Which is why you find a man (yes, a man) like Jesus commiserating with "sinners" (ill people) while chastising the norm (accepted avoidant fragmentors)

Why should you use an old culture for the endospore stain?

Spores are typically formed when an organism is enduring stressful conditions. If you wait until the culture is old then it is likely that some of the organisms will be experiencing stressful conditions such as lack of nutrients. It helps if you remember why the organism forms spores at all! The organism is protecting itself against harsh conditions, the spore will not germinate until conditions favour growth.

Is 90 a high count for liver enzymes?

A count of 90 for liver enzymes may be considered high, depending on the specific enzyme being measured. Elevated liver enzyme levels can indicate liver damage or disease, and further evaluation by a doctor is recommended to determine the cause and develop a treatment plan.
