<span>Other than the fact that our cells would never be able to fulfill different functions without cell differentiation, each and every cell would do the same thing. Our bodies could never be able to take shape. Hope the answer helps. </span>
Okay so here's the approach I took:
The potential difference in each of the circuits must be the same so if we derive equations for both the potential differences we can set them equal to each other and solve for R1:
In the first circuit
V = 2.2(R1)
In the second we have to find the equivalent resistor, since they are connected in series:
1/R1 + 1/R2 + 1/R3... = Rt
We have R2 so...
1/R1 + 1/3.1 = Rt
1/R1 + 0.323 = Rt
So...
V = 1.4(1/R1 + 0.323)
Set those equal:
2.2R1 = 1.4(1/R1 + 0.323)
2.2R1 = 1.4(1/R1) + 0.4522
Now multiply everything by R1 so we can combine like terms:
2.2R1^2 = 1.4 + 0.4522R1
Isolate to form a quadratic
2.2R1^2 - 0.4522R1 - 1.4 = 0
Solving this quadratic:
R1 = 0.90708 or R1 = -0.701
Since R cannot be negative
R1 = 0.907 ohms
If a current of 1 ampere enters a parallel circuit at Point A. This 1 ampere of current will divide between Resistors R1 and R2 and then recombine at Point B
<h3>
Parallel circuit</h3>
A parallel circuit is a circuit with separate branches with a common endpoint. In a parallel circuit, the voltage across each branch is the same but the currents vary. The total current is the sum of the currents flowing through each component.
If a current of 1 ampere enters a parallel circuit at Point A. This 1 ampere of current will divide between Resistors R1 and R2 and then recombine at Point B.

As you descend, the pressure of the air increases and the volume of the air decreases as it becomes squeezed by the pressure.
The ratio is 1/pressure.
At 20 meters below the surface, the pressure of the air is 3 atm.
Time that oxygen tank can last = 1/3 x 60 = 20 minutes <span />
One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one. Option A is correct.
<h3>What is electromagnet?</h3>
The magnetic field of an electromagnet is created by an electric current. Electromagnets are caused from conducting wire wriggled into a coil.
A magnetic field is created in the hole by a current passing through the wire.
The magnetic field production is increased by;
1) increasing the number of turns
2) increase the area of the loop
3) by moving the magnet faster
One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one.
Hence, option A is correct.
