6. My wonderful students set up an experiment to determine if population density affected plant growth. Students took radish seeds and planted 2 seeds in one container and 8 seeds in the other container. Both containers were the same size, and both contained the same amount and type of soil. They carefully watered each container with the same amount of water each day and they put both containers in the same location to recieve the same amount of sunlight. My students observed the plants growth and saw that one container's plants looked healthier, greener, and with thicker stems than the other one. What is the independant variable?
-
Same cup, soil, sunlight.....
-
2 seed in one cup, 8 in the other
-
Answer option 3
-
Answer option 4
Correct Answer
A. 2 seed in one cup, 8 in the otherExplanation
The independent variable in this experiment is the number of seeds planted in each container. This is because the students intentionally manipulated this variable by planting 2 seeds in one container and 8 seeds in the other. By comparing the growth of the plants in each container, the students can determine if population density (represented by the number of seeds) affects plant growth. The other factors mentioned, such as the cup, soil, sunlight, and amount of water, are all controlled variables that were kept the same in both containers to ensure a fair comparison.Rate this question:

A carrying capacity is anything that restricts the number of individuals in a population
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because carrying capacity refers to the maximum number of individuals that an environment can sustainably support. It is determined by factors such as available resources, space, and competition. Carrying capacity does not restrict the number of individuals in a population, but rather sets a limit on how many individuals can be supported without causing environmental degradation or resource depletion.Rate this question:
