Given that,
Current = ∞
We know that,
Ohm's law :
Ohm's law is defined as,
The voltage of the circuit is directly proportional to the current of the circuit.

Or,
The voltage of the circuit is equal to the product of current and resistance.
In mathematically,

Where, V = voltage
I = current
R = resistance
According to ohm's law,
The current in the circuit is

If the current is very less then the resistance will be infinity.
If the is reach to infinity then the resistance will be very low.
Hence, The resistance becomes very low.
The correct answers are:
B. plant growth;
C. animal actions;
The mechanical weathering is a type of weathering where physical force is included into the breaking up of the rocks. The plants and the animals are both causing this type of weathering with their actions. The plants can cause mechanical weathering with their roots, as they grow and surround a rock, they are able to create such a pressure that they can break the rock apart. Also, as their trunks are getting bigger, if there's rocks right next to them, the pressure from the growing of the trunk will crack the rocks. The animals are able to move the rocks, as well as pushing them, or even deliberately throwing them, so they manage to break up parts of them and cause mechanical weathering.
Answer:
The purpose of regular health examination is to evaluate health status, screen for risk factors and disease, and provide preventive counseling interventions. The major benefits of regular health examination is early detection of treatable disease.
