1. Miticide means:

Explanation

Miticide refers to a substance or product used to kill or control mites. Mites are tiny arachnids that can infest plants, animals, and humans, causing various problems and diseases. Therefore, a miticide is specifically designed to target and eliminate mites, making "Mite Killer" the correct answer. "Herbicide" is used to kill weeds, "Airborne Pollutant" refers to harmful substances in the air, and "Dirty Water" indicates contaminated or impure water, which are not relevant to the definition of miticide.

2. What is the meaning of Chromatid?

Explanation

A chromatid is a part of a chromosome. During cell division, each chromosome duplicates itself, resulting in two identical sister chromatids that are held together by a structure called the centromere. These sister chromatids contain the same genetic information and are eventually separated during cell division to form two new cells. Therefore, the correct answer is "Chromosome Part".

Submit
3. Macrophage means:

Explanation

Macrophage refers to a type of cell in the immune system that plays a crucial role in engulfing and destroying pathogens, dead cells, and other foreign substances. They are large white blood cells that are part of the body's defense mechanism against infections and diseases. Macrophages are involved in the process of inflammation and also help in presenting antigens to activate other immune cells.

Submit
4. Congenital means:

Explanation

Congenital refers to a condition or trait that is present at birth. It indicates that the condition or trait is present from the moment of birth, rather than being acquired later in life. This term is commonly used in the medical field to describe conditions or abnormalities that are present in a baby at the time of their birth.

Submit
5. Cyanosis means:

Explanation

Cyanosis refers to a condition where the skin appears bluish in color. This occurs when there is a lack of oxygen in the blood, leading to poor circulation or respiratory problems. The bluish discoloration is particularly noticeable in areas with less pigmentation, such as the lips, nail beds, and mucous membranes. It is an important clinical sign that indicates a potential lack of oxygen in the body and should be evaluated promptly by a healthcare professional.

Submit
6. Hit-and-run effect means:

Explanation

The term "hit-and-run effect" refers to a situation where a toxic substance causes harmful effects on an organism after a single exposure. This means that even a brief exposure to the toxin can have severe consequences on the organism's health. It implies that the toxic substance does not require repeated or prolonged exposure to cause toxicity.

Submit
7. What can be used to make a Codex Alimentarius?

Explanation

A Codex Alimentarius is a collection of internationally recognized food standards, guidelines, and codes of practice. It is used to ensure the safety, quality, and fairness of food trade. Therefore, the correct answer is "Food Standards" as they are the essential component for making a Codex Alimentarius. Poisoned Papers, Frog-Produced Toxin, and Disease Catalog do not align with the purpose of creating a Codex Alimentarius.

Submit
8. Which of these is Clastogen?

Explanation

A clastogen is a substance or agent that causes breaks or rearrangements in chromosomes, leading to genetic mutations. Chromosome breakers specifically refer to substances that cause breaks in chromosomes. Therefore, the correct answer is "Chromosome Breaker" as it accurately describes a clastogen's role in causing chromosome damage.

Submit
9. Choose the right answer for Biostatic

Explanation

The correct answer is "Arrests Organism Growth". This answer is correct because "biostatic" refers to something that stops or inhibits the growth or activity of living organisms. It does not necessarily heal or measure organisms, and it is not related to freezing them.

Submit
10. Which one is correct for Itai-itai disease?

Explanation

Cadmium-Induced Illness is the correct answer for Itai-itai disease. Itai-itai disease is a condition caused by long-term exposure to cadmium, a toxic heavy metal. It primarily affects the bones and kidneys, causing severe pain and deformities in the affected individuals. The name "Itai-itai" comes from the Japanese expression for "ouch-ouch" which reflects the excruciating pain experienced by the patients. The disease is primarily associated with industrial pollution and contaminated water sources.

Submit
11. Which of the following is the part of the Bagassosis?

Explanation

Bagassosis is a lung disease caused by the inhalation of dust from moldy sugarcane. It primarily affects individuals working in sugarcane mills or those exposed to moldy sugarcane. The symptoms of bagassosis include coughing, wheezing, shortness of breath, and chest tightness. Therefore, lung disease is the correct answer as it accurately represents the condition associated with bagassosis.

Submit
12. Congener is what?

Explanation

Congener refers to a related chemical. In the context of this question, it is implied that the term "congener" is being used in relation to chemicals. Therefore, the correct answer is "Related Chemical." It is important to note that without further context or information, it is difficult to provide a more specific explanation regarding the term "congener."

Submit
13. Ultrafine Particle means:

Explanation

Ultrafine particles refer to particles that have a size smaller than 100 nanometers. These particles are extremely small and can be found in various environments, including indoor and outdoor air. Due to their small size, ultrafine particles have unique properties and behavior compared to larger particles. They can penetrate deep into the respiratory system and have the potential to cause adverse health effects. Therefore, it is important to monitor and regulate the levels of ultrafine particles in order to maintain a safe and healthy environment.

Submit
14. What is the definition of Ischemia?

Explanation

Ischemia refers to a condition characterized by a deficiency in blood supply to a particular organ or tissue. This can lead to inadequate oxygen and nutrient supply, resulting in damage or dysfunction of the affected area. Therefore, the correct answer is "Blood Supply Deficiency."

Submit
15. What is Weibull model made out of?

Explanation

The Weibull model is a statistical model commonly used in reliability engineering to analyze the failure rates of systems. It is particularly useful for modeling the time-to-failure of a component or system. The model is based on the dose-response concept, which relates the effect of a stimulus (dose) on a biological system (response). In this case, the dose refers to the stress or load applied to the system, and the response is the failure time. Therefore, the Weibull model is made out of the dose-response model.
