Hello I need these answers.. I didn’t study and I’m in serious trouble! 1. what will happen to the 6 V lamp in this circuit if the switch is changed to position 1, where there will be a complete path for the electricity to flow?
a - the lamp will glow continuously
b - there will be a short-circuit
c - the lamp will start flashing on and off
d - the lamp will glow brightly once , and then fade

2.the circuit shown here is made using a 24 V heater , a switch , and two 12 v batteries, similar to those found under the hood of an automobile. as you can see , the heater is not working. why is this?
a - the batteries are not powerful enough
b - the switch is in the “off” position
c - the wires between the batteries , the heater , and the switch are connected incorrectly
d - the terminals of one of the batteries are not connected to the circuit

Which entry is in the wrong position in the table?

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
