Answer:

Total resistance, R' = 3 ohms

Explanation:

It is given that, a circuit contains two devices that are connected in parallel. There values are given as :

Resistor 1, R_1=12\ \Omega

Resistor 2, R_2=4\ \Omega

The total resistance in parallel combination is given by :

\dfrac{1}{R'}=\dfrac{1}{R_1}+\dfrac{1}{R_2}

\dfrac{1}{R'}=\dfrac{1}{12}+\dfrac{1}{4}

R' = 3 ohms

So, the total resistance of the two devices is 3 ohms. Hence, this is the required solution.

During the fourth generation, 200 dark moths were captured from clean forest B. About how many total moths were recaptured from
Talja [164]

Answer:

The answer is 1050

Explanation:

A simple trace on the graph representing the information in the question shows that on graph B (which represents the moths captured per generation from the polluted forest), approximately 1050 moths were captured in the same generation when 200 dark months were captured from the clean forest A.

The above experiment was carried out to determine the extent of Industrial melanism.

Industrial Melanism refers to the artificially induced coloration (mostly dark hues) which affect both plants and animals in some cases stifling their growth or even killing them.

Whereas dark-colored moths were prevalent in the polluted areas after the Industrial Revolution, their numbers declined and more butter-colored moths emerged as pollution reduced.
