Answer:
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
Answer:
Is used to prevent contamination from pathogens.
Explanation:
Pathogens are disease causing organisms. In a clinical setting or even in the laboratory, a person has to use the strictest means of disease prevention and even re-infection (for patients). Aseptic technique is important to protect yourself, other workers and patients from infection and from the spread of pathogens. It effectively maximizes the presence of pathogens and totally eliminate them. This is possible from simple measures like using your PPE which must all be sterile. From your gloves, gowns etc to your equipments used during any procedure. Also disinfection of your work place is important too either by concurrent disinfection or intermittent disinfection.
<u>Answer</u>:
The correct answer is:
A. straightening the wire, because the number of turns of the wire around the iron core is directly proportional with the strength of electromagnet.
and,
C. decreasing the voltage is correct, by decreasing the voltage, the current will decrease and this leads to weaker electromagnet.
<u>Explanation:</u>
Simply, the electromagnet is used to convert electric energy to magnetic energy.
<u>Basic idea:</u>
- The basic idea of the electromagnet is, when the electric current passes through a wire it creates a weak magnetic field
<u>Components of simple electromagnet:</u>
- Battery: source of electricity
- Electric wire: the electric current passes through it
- Iron core: will convert to temporary magnet
<u>The strength of electromagnet is simply defined by the strength of magnetic field that synthesized by the electric current.</u>
<u>Factors affects strength of electromagnet:</u>
- <u>Strength of current</u>: by increasing the current that passes through the wire the magnetic field will increase, ( so decreasing the voltage will decrease the current produced and will decrease the strength of electromagnet)
- <u>Number of loops or number of turns of the wire</u><u>:</u> the more the number of turns, the more the electric field produced, (so straightening the wire will decrease the magnetic field induced and decrease the strength of electromagnet).
- <u>The metal core</u><u>:</u> iron core makes stronger electromagnet.
- <u>Decreasing the resistance:</u> this will increase the current produced and will increase strength of electromagnet.

Answer:
The main difference between the two cycles would be how in the lysogenic cycle the bacteriophage uses the host cell´s own systems for replication and reproduction, but without harming the host cell, while in the lytic cycle this passiveness changes and the bacteriophage becomes highly virulent and kills the host cell.
Explanation:
Bacteriophages are viruses that infect bacteria. In their reproductive cycles, they have two stages, or cycles themselves. The first is the lysogenic cycle and the second the lytic cycle. In the lysogenic cycle the phage´s genetic material merges with that of the bacteria and the virus uses the host cell´s machinery to have its genetic material replicated and new phages produced. However, during this stage, the phage remains merged and does not affect its host much. There will be no active ensembling of new phages and thus the two can coexist, and almost collaborate. This happens thanks to repressor molecules that maintain the phage´s genetic material static. However, a phage may change this and activate itself, using the cell´s systems to start assembling new phages. WHen this happens, the phage becomes highly virulent and in the end dissolves not just the host cell´s genetic material, but will also kill the host cell itself.
