<span>The burners must be turned off because, in the case of liquid chromatography, the eluant solvents being used are flammable. Leaving the burners lit could cause the eluant to catch on fire, putting the scientist at risk.</span>
Answer:
C, Both parents have the blue-eyed gene.
<span>The answer is d. front. A front is the narrow region between two air masses of different densities. The interaction of the air masses cause the mass that is less dense to rise. Once air rises it cools and condenses to form clouds and eventually leads to precipitation. Using cold fronts as an example, the denser mass of cold air forces the lighter warm air to rise. </span>
Recombinant DNA technology has also proven important to the production of vaccines and protein therapies such as human insulin, interferon and human growth hormone. It is also used to produce clotting factors for treating haemophilia and in the development of gene therapy. hope that helps
The answer is 2 times.
In parallel DC circuit the power (P) can be calculated by using the values of total current (I) and resistance (R):
P = I²R
The old power is:
Po = Io² x Ro
Io = 4 A
Ro = 0.5 ohms (Ω)
So, <span>Po = 4² A x 0.5 </span>Ω<span> = 8 W</span>
The new power is:
Pn = In² x Rn
In = 4 A x 2 = 8 A
Rn = 0.5 Ω ÷ 2 = 0.25 Ω
So, Po = 8² A x 0.25 <span>Ω </span>= 16 W
Pn ÷ Po = 16 W ÷ 8 W = 2
Thus, the new power is 2 x higher than the old power.
