There is gravity everywhere. It gives shape to the orbits of the planets, the solar system, and even galaxies. Gravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits. Gravity from Earth keeps the Moon and human-made satellites in orbit. It is true that gravity decreases with distance, so it is possible to be far away from a planet or star and feel less gravity. But that doesn't account for the weightless feeling that astronauts experience in space. The reason that astronauts feel weightless actually has to do with their position compared to their spaceship. We feel weight on Earth because gravity is pulling us down, while the floor or ground stop us from falling. We are pressed against it. Any ship in orbit around the Earth is falling slowly to Earth. Since the ship and the astronauts are falling at the same speed, the astronauts don't press against anything, so they feel weightless.You can feel something very like what the astronauts feel for a moment in a fast-moving elevator going down or in a roller coaster, when you start going down a big hill. You are going down rapidly, but so is the roller coaster or the elevator so for a second you feel weightless.

Answer;
-They cause diseases that are diagnosed by finding microscopic eggs in clinical specimens.
Explanation;
-Parasitic worms are organisms that live in and feed off a living host. There are a variety of parasitic worms that can take up residence in humans. Common types of intestinal worms include: flatworms, which include tapeworms and flukes. roundworms, which cause ascariasis, pinworm, and hookworm infections.
Microbiologists study parasitology which is the study of the relationship between parasites and their hosts. Parasites causes important diseases of human, animals and even plants. The study makes important step-forward in mission to tackle parasitic worm infections.
