In one study, half of the rats are given one food pellet each time they correctly run a maze, and the other half of the rats are
given two food pellets each time theycorrectly run a maze. The researchers record the average amount of time it takes the rats to run the maze. In this study, the number of food pellets represents the __________ variable.
independent
Researchers record the average time it takes rats to complete the maze. In this study, the number of feed pellets was independent as per Manipulation of the Independent Variable
Manipulation of the Independent Variable Again, manipulating an independent variable involves systematically altering its levels so that different groups of participants are exposed to different levels of that variable, or This means that the groups will be exposed to different levels at different times. Independent variables are variables that researchers manipulate to better understand how phenomena, structure, and behavior are related to the dependent variable and Alternative Hypothesis . Instrumental variables are the independent variables in an experiment. It's called "manipulated" because it's something you can change. That is, you can decide in advance whether to increase or decrease. Experiments should always have only one instrumental variable.

A place halfway between the equator (0 degrees) and the north pole (90 degrees) is at 45 degrees north latitude; a place between the equator and the south pole is at 45 degrees south latitude. The equator serves as a boundary between two halves or hemispheres of the earth
The answer is male biased sex ratio. The operational sex ratio is distressed by the span of time each sex expends in considerate for young or in on the road to recovery from mating. For example, if females cease mating commotion to care for young but males do not then more males would be ready to mate, thus creating a male biased operational sex ratio.
