Hunter-Best [27]

The right answer is C) Make sure electrical hazards are resolved immediately.

The different electrical risks are:

Risk of direct contact with an electrified part

Risk of indirect contact with a conductive part accidentally switched on

Risk of "remote" electrification (without contact), by priming

Risks of fire and exposure, due in particular to arcing during a short circuit, and the accumulation of static electricity causing sparks.

A ____ is an agent that can cause infections and diseases.
Darina [25.2K]

<em>A </em><em>virus </em><em>is an agent that causes infections and diseases. </em>

<h2>Further Explanation </h2>

Viruses are microscopic parasites that infect cells of biological organisms. Viruses are obligate parasites, this is because viruses can only reproduce in living material by invading and utilizing the cells of living things because viruses do not have cellular equipment to reproduce themselves.

The term virus usually refers to particles that infect eukaryote cells (multicellular organisms and many types of single-cell organisms), while the term bacteriophage or phage is used for types that attack types of prokaryotic cells (bacteria and other organisms that do not cell nucleated).

The virus has been infecting since the days before Christ, this is evidenced by the existence of several discoveries, namely reports of virus infections in hieroglyphics in Memphis, the capital of ancient Egypt (1400 BC) which shows the existence of poliomyelitis. In addition, King Pharaoh Ramses V died in 1196 BC and is believed to have died of the smallpox virus.

In 1880, Louis Pasteur and Robert Koch put forward a "germ theory" namely that microorganisms are the cause of disease. At that time also the famous Koch Postulate which is very well known today, namely:

  • A disease agent must be present in every case of the disease
  • The agent must be isolated from the host and can be grown in vitro
  • When the muri agent culture is inoculated into susceptible healthy host cells, it can cause disease
  • The same agent can be taken and re-isolated from the infected host

<h3>Various kinds of viral infections </h3>
  • Acute infections are infections that last for a short time but can also be fatal.
  • Chronic infection is a prolonged viral infection so there is a risk of symptoms of the disease coming back.

What structural feature in a molecule is necessary for a gas to absorb ir radiation?.
dybincka [34]

The structural feature in a molecule necessary for a gas to absorb IR radiation is: a net change in dipole moment due to the vibration or rotation of the molecule.

IR radiation is the infrared radiation. In the electromagnetic spectrum, its value ranges from  700 nanometers to 1 millimeter. The waves are longer than that of visible light and shorter than the radio waves. The waves are not visible to the human eye.

Dipole moment is a vector quantity. It is equal to the charge of the molecules multiplied by the distance between the two charges. In a dipole there is a positive charge at one end and a negative at the other. The direction is considered from negative to positive.
