Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.
Answer: chain link fence
Peptidoglycan could be found in high number on gram positive cell walls. The structure of peptidoglycan looks like a cross link which makes it sturdy, so rain coat would be false. It is not an impenetrable brick wall because it still allow some ion and food pass through it. Sugar candy coat sounds good but chain link fence would be better.
Answer:
When I first read this question, all I could think about was the capsized fishing charter called, “the Erik”. The inept captain and crew of this boat caused the death of four passengers while three others remain missing. This disaster occurred back in 2011. I knew two of the passengers. One was recovered in 2013. The other is still listed as missing. However, this question concerns the “best story”. So, I’ll give you the accounts of my own experience. Back in 2013, my group of long-range fishing friends had chartered our annual 8-day trip out of Point Loma, San Diego. We had always chartered the same boat; the Shogun. At our traditional dinner the night before boarding, I remember the most notable topic being discussed was the remnants of Hurricane Ingrid. Ingrid had caused high winds and seas in the area where we wanted to fish.
You see, passive transport needs no energy. So that being said, it moves from areas with high concentration to areas with low concentration.
Hope that helps!
