Which form of radiation is used to kill microorganisms?

Answers

Answer 1

Answer:

Answer:

X- rays, gamma rays.

Explanation:

Ionizing radiations are used to kill microorganisms. These radiations include x-rays, gamma rays and high energy electron beam. These radiations are passed into the cell. As a result, the cell component and the molecular structure gets damaged. These rays are used to kill microorganisms because they penetrate more than other rays.

Answer 2

Answer: Gamma Rays, Ionizing Radiation, Xrays

An electron microscope is usually used for microorganisms that are _____. too small to be seen with the unaided eye too small to be seen with an optical microscope not possible to observe with any instrument

Answers

Answer;

too small to be seen with an optical microscope

Explanation;

An electron microscope is a type of microscope that is used to observe very tiny specimens whose features can not be observed by other types of microscopes. It uses a beam of electrons to generate an image of a given specimen whose features can be clearly observed and studied.
Electron microscope has very high resolution and magnification as compared to other optical microscope hence can be observed in the study of micro-organisms such as viruses which would be difficult to study their features using optical microscopes.

An electron microscope is usually used for microorganisms that are too small to be seen with the unaided eye. You can adjust the size of the microorganism to see it more clearly by adjusting its magnification lens.

Which scientist first stated the relationship between buoyant force and weight of displaced fluid

Answers

Answer:

Archimedes

Explanation:

Archimedes suggested in his work, called On Floating Bodies that "Any object, totally or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." This was later known as the Archimedes principle.

He was Archimedes of Syracuse.

Which of the following does not represent a mechanical wave?sound
waves in the ocean
waves in a wheat field
light

Answers

Answer:

The other person who answered is incorrect- the real answer is light.

Explanation:

A mechanical wave is a wave that requires a medium. A medium is any substance that has a defined set of physical properties and can transmit energy. A medium can be a solid, liquid, or gas. Some examples of a medium include an iron bar, the ground, water, lava, air, and helium in a balloon.

The answer is not sound because sound travels through waves through the air. If you were to put a source of sound in a container that contains no air, you would not be able to hear the sound through the container. Since sound has a wave and a medium, it is a mechanical wave.

The answer is not waves in the ocean because, obviously, this is a wave. Its medium is the water. Since it has a wave and a medium, it is a mechanical wave.

The answer is not waves in a wheat field because, again, this is a wave. The medium is the air. Since it has a wave and a medium, it is a mechanical wave.

The answer is light. Light travels through electromagnetic waves. However, it does not require a medium. Light can travel not only through air and solid materials, but also through the vacuum of space. Since light does not require a medium, it is not a mechanical wave.

I hope this helps !! :)
