PLEASE HELP ME ANSWER THIS PLZ MARK BRAINLIST WHEN I CAN. Why is it important that you keep two variables constant (such as light level and color) while you're testing how a third variable(CO2 level) affects photosynthesis

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
