Answer:
1. IV: Time the Bell is rang DV: Time it takes to learn the task
2. IV: Nitrogen fertilizers DV: Diversity of fish
3. IV: Time of radiation DV: Percentage of successful germination
Explanation:
The independent variable of an experiment refers to the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable while the dependent variable is the variable that responds to the changes made to the independent variable.
1. In scenario 1, the TIME THE BELL RINGS is the independent variable because that is what the experimenter controls or has power to change. On the other hand, the dependent variable is the TIME IT TAKES TO LEARN THE TASK because it is the measured variable that responds to the independent variable.
2. In scenario 2, the USE OF NITROGEN FERTILIZER is the independent variable while the DIVERSITY OF FISH is the dependent variable.
3. In case 3, the TIME OF RADIATION is the independent variable while the PERCENTAGE OF SUCCESSFUL GERMINATION is the dependent variable.
Answer:
Flowers are derived evolutionary from modified <u>leaves</u>.
Explanation:
Flowers are modified leaves possessed only by the angiosperms, which are relatively late to appear in the fossil record. The flowering plants have long been assumed to have evolved from within the gymnosperms; according to the traditional morphological view, they are closely allied to the Gnetales.
Yes it does because it depends on how strong the man is on either end of the rope
The salient features of this case are severe headache, high grade fever, and a stiff neck (nuchal rigidity). These are classic signs and symptoms of meningitis. Therefore the nurse should look for other signs and symptoms that will support the diagnosis of meningitis with the hallmark of meningeal inflammation (i.e. Brudzinski's sign, Kernig's sign, passive neck flexion test, etc.)
