Metaplasia means:
- A.
Recycling Program
- B.
Large Molecules
- C.
Plastic Waste
- D.
Abnormal Tissue Change
Correct Answer
D. Abnormal Tissue ChangeExplanation
Metaplasia refers to the abnormal change in the type of cells in a tissue. It occurs when one mature cell type is replaced by another, which is not normally found in that tissue. This change can be a response to chronic irritation, inflammation, or other pathological processes. It is a reversible process, meaning that if the underlying cause is removed, the tissue can revert back to its normal state. Therefore, the correct answer for this question is "Abnormal Tissue Change".Rate this question:

Octanol-Water Partition Coefficient means:
- A.
Solubility Ratio
- B.
Alcohol Strength
- C.
Fluid Flow Rate
- D.
Water Pollution Impact
Correct Answer
A. Solubility RatioExplanation
Octanol-Water Partition Coefficient refers to the solubility ratio of a compound between octanol (a non-polar solvent) and water (a polar solvent). It is a measure of how a compound distributes itself between these two phases, which is important in understanding its behavior in biological systems and environmental fate. A higher partition coefficient indicates greater solubility in octanol and lower solubility in water, while a lower partition coefficient indicates the opposite. Therefore, the correct answer is "Solubility Ratio".Rate this question:

BMD means:
- A.
Benchmark Duration
- B.
Benchmark Dose
- C.
Breck-Morgan Dystrophy
- D.
Back Mutation Disease
Correct Answer
B. Benchmark DoseExplanation
BMD stands for Benchmark Dose. Benchmark Dose is a statistical method used in toxicology to estimate the dose at which a specific response level is expected to occur. It is used to determine the safe level of exposure to a substance by estimating the dose that would cause a specific adverse effect in a population. This method helps in assessing the potential risks associated with exposure to certain substances and setting appropriate safety standards.Rate this question:

What is the meaning of Icterus?
- A.
Mercury-Based Compound
- B.
Excess Bile Pigment
- C.
Lung Disease
- D.
Sight-Damaging
Correct Answer
B. Excess Bile PigmentExplanation
Icterus refers to a medical condition characterized by the presence of excess bile pigment in the bloodstream, resulting in a yellowing of the skin and eyes, also known as jaundice. This condition can occur due to various reasons such as liver disease, gallstones, or certain medications. Therefore, the correct answer "Excess Bile Pigment" accurately describes the meaning of Icterus.Rate this question:

Meaning Of TNF
- A.
Tumor Necrosis Factor
- B.
Topical Narcotic Foam
- C.
Total Nerve Failure
- D.
Top Natural Factor
Correct Answer
A. Tumor Necrosis FactorExplanation
TNF stands for Tumor Necrosis Factor. Tumor Necrosis Factor is a protein produced by the immune system that plays a role in inflammation and cell death. It is involved in various physiological processes such as immune response, regulation of cell growth, and apoptosis. TNF is particularly known for its role in promoting cell death in tumor cells, hence the name "Tumor Necrosis Factor".Rate this question:
