Tailings is the right answer.
The research party began by exploring the embryonic development of whales' cousins, the dolphins. These creatures are intriguing because, for a brief time during development, they sprout hind limbs . That's why dolphins lose their 'legs'.” In whales, however, the story is more complex.
The terms with respect to their definitions are matched below:
- Independent variable: The time the popcorn is cooked.
- Controlled variable: The brand of popcorn.
- Responding variable: The number of unpopped popcorn kernels.
<h3>What is an Independent variable?</h3>
An independent variable may be defined as a variable that stands isolated and isn't altered by the other variables you are trying to measure in your experiments.
A controlled variable may be defined as a variable that remains unchanged during the course of whole experiments.
A responding variable may be defined as a variable that responds according to the effect of controlled and independent variables.
Therefore, it is well described above.
