Independent variable: is the UV light exposure
Control group: people not exposed (sample b)
Dependent variable: skin cancer
Experimental group: (sample A)
Answer:
The two environmental factors are temperature and pH and with that, denaturation occurs. In other words, temperature and pH would affect the protein structure, which it would change their shape and possibly it won't perform its normal function.
Explanation:
Answer:
Option D, both A and B
Explanation:
The potential difference is created across a battery (between its two terminal –one positive and the other one negative) when work is done to move a charge from one point to another. This potential difference is measured in volts. 1 volt is the potential difference between two points when one joule of potential energy is spent to move a charge of one coulomb from one point to the other.
Voltage drop across a circuit is the amount of electric current lost due to resistance/ impedance with in the cables of the circuit.
Hence, both potential difference and voltage drop occurs across the circuit,
Option D is correct.
