Polio is caused by the poliovirus, which is a highly contagious virus that primarily spreads through person-to-person contact. There are three strains of the poliovirus, known as type 1, type 2, and type 3.

Vaccination has been highly effective in reducing the incidence of polio worldwide. **

Certainly! Causative verbs are used to indicate that someone or something causes another person to do something. They can be divided into two categories: causative make and causative have. Causative make is used when someone forces or compels another person to do something, while causative have is used when someone arranges for another person to do something. Examples of causative make include "I made him clean his room" and "She made me study for the exam." Examples of causative have include "I had my car fixed" and "She had her hair cut." **

The main difference between causative passive and passive is the level of control over the action. In passive voice, the subject of the sentence is the receiver of the action, while in causative passive, the subject causes someone else to do the action. For example, in passive voice, "The book was read by the student," the student is the receiver of the action. In causative passive, "The teacher had the student read the book," the student is being caused to perform the action by the teacher. **

Athlete's foot is a common fungal infection that typically affects the skin between the toes. It is usually characterized by redness, itching, and peeling of the skin. To determine the causative agent of athlete's foot, a healthcare provider may perform a skin scraping and examine it under a microscope to identify the presence of fungi such as Trichophyton, Epidermophyton, or Microsporum. Additionally, a culture of the skin sample may be done to confirm the specific type of fungus causing the infection. **

A military radar is a system used by the military to detect and track aircraft, missiles, ships, and other objects in the air or on the ground. It uses radio waves to determine the range, angle, and velocity of the objects it detects. Military radars are an essential tool for surveillance, early warning, and air defense, providing crucial information for military operations and national security. They can be deployed on land, at sea, or in the air, and are designed to operate in various environmental conditions and combat scenarios. **

Yes, there are flight radars that track military aircraft. However, the information available on these radars is often limited due to security and operational reasons. Some flight tracking websites and apps may display military aircraft positions, but the data is usually less detailed and may not be as accurate as the information for civilian flights. Additionally, some military aircraft may not be visible on public flight radars at all, especially during sensitive operations or exercises. **
