A.
The independent variable (experimental variable) is the exposure to UV lights of the tadpoles because it is being varied. The dependent variable is the survival of the tadpoles, because it is the one being affected by the independent variable.
B.
The information from the experiment does not support the hypothesis because an equal number of tadpoles remain, while the hypothesis predicted that less would remain in the tank exposed to UV light.
C.
Other factors such as temperature of the water may be affecting the frog populations.
D.
The control group was the tank covered with glass and the experimental group was the tank covered with acrylic plexiglass
E.
The difference was that one group was exposed to the UV light, while the other group was not. No, they should not be different in any other way, because that may lead to inconclusive experimental results.
Answer:
Instrumental learning
Explanation:
Associative learning is a form of learning which is performed when two or more events or stimuli controls the learning behaviour. The instrumental learning is a type of learning in which the learning process is associated with the consequence or result of the action.
In the given question, the mouse learns how to step on the lever as a result of the received food in the form of reward or he learned because he received the treatment, therefore, this act of learning will be considered the instrumental learning.
Thus, Instrumental learning is correct.
Answer:
In 1831, Darwin embarked on a voyage aboard a ship of the British Royal Navy, the HMS Beagle, employed as a naturalist. ... Darwin's analysis of the plants and animals he gathered led him to question how species form and change over time. This work convinced him of the insight that he is most famous for—natural selection
