Answer:
1. magnetometer, 2. reactor, 3. megawatt, 4. infrared, 5. turbine.
Explanation:
A magnetometer is an electronic instrument used to measure magnetic fields.
(1. <em>an instrument to measure magnetism</em> - magnetometer)
A reactor is a device used for the production of controlled nuclear energy, there are two principles in which nuclear reactors can be based: (i) Fission, (ii) Fusion.
(2. <em>a system for the production of controlled nuclear energy</em> - reactor)
A million watts equals a megawatt, a power SI unit.
(3. <em>a million watts; thousand kilowatts</em> - megawatt)
Infrared radiation corresponds to electromagnetic waves whose wavelength is between 0.7 to 1000 micrometers.
(4. <em>invisible radiation with waves longer than red</em> - infrared)
A turbine is mechanical device which generates mechanical work at the expense of fluid energy.
(5. <em>An engine in which a wheel turns by the force of wind, water or steam</em> - turbine)
1) deep trenches
2) active volcanoes
3) arcs of islands along the tectonic boundaries
4) in some cases, mountain ranges
Answer: Nerve cells and muscle cells
Explanation:
The nerve cells and the muscles cells of the body plays important role in the conduction of the signals.
Calcium ion helps in the signal conduction so its role is majorly important in nerve cells and muscle cells.
The calcium signalling can be defined as the use of calcium ions for the cellular signalling, it enters the cytoplasm and exerts allosteric regulatory enzymes in many of the proteins and enzymes.
This derives many intracellular processes and signal transmission is one of the following.
I think is False! Because it is not example of a disaccharide it is not saccharin-aspartame molecule.
Answer:
54
Explanation:
Given symbol of the element:
I⁻
Number of electrons found in an ion with the symbol:
This is a iodine ion:
For an atom of iodine:
Electrons = 53
Protons = 53
Neutrons = 74
An ion of iodine is one that has lost or gained electrons.
For this one, we have a negatively charged ion which implies that the number of electrons is 1 more than that of the protons.
So, number of electrons = 53 + 1 = 54
The number of electrons in this ion is 54
