If there is an environmental or selective pressure it will contribute to the evolution of an organism by giving an adnantage to the organisms of a population who have a trait which allows them to survive that change. The advantageous genes will be passed on and the number of organisms with the desirable feature will increase over time, however the number of organisms that lack the characteristic will decrease over time. This is evolution by natural selection.

Answer:
no
Explanation:
theyre different shapes. go to bed.
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.
