A circuit contains two light bulbs connected in parallel. What would happen to the brightness of each light bulb if two more light bulbs were added in parallel to the first ones? The brightness of each bulb would decrease because the total resistance of the circuit would decrease.
The brightness of each bulb would increase because the total resistance of the circuit would increase.
The brightness of each bulb would remain the same even though the total resistance of the circuit would decrease.
The brightness of each bulb would remain the same even though the total resistance of the circuit would increase.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).
