No they did not
that should be the right answer
Uracil (U) is not part of DNA but is part of RNA
After passing through the cornea, light travels through the pupil (the black dot in the middle of the eye). The iris—the circular<span>, colored area of the eye that surrounds the pupil—controls the amount of light that enters the eye.</span>
Answer:
The question: Do mice live longer when they are fed high sugar diets?
Hypothesis: There are two hypothesis the null hypothesis which we assume is correct, it states that a high sugar diet will have no effect on the life span of a mouse and an alternate hypothesis that we accept if evidence shows that sugar does increase the life span if mice. It says a high sugar diet does incerease the life span of mice.
Prediction: Assume that the null hypothesis is correct. High sugar diets will not increase the life span of the mice.
Collect data through experimentation. Use some mice as a 'control'. These mice will not undergo any changes but will be kept for comparison. Expose some other mice to high sugar diets and the compare the outcome with the 'control' mice.
Analyzing: From the experiment this you can choose which hypothesis you are going to accept. I.e. null: no change or alternate: there was a change and do some extra research to back up your hypothesis.
Hope this helps :)

define amphibian ?
Amphibians are four-limbed, ectothermic animals that belong to the class Amphibia. The phylum Lissamphibia includes every extant amphibian. They live in a broad range of habitats, with the majority of species being found in freshwater aquatic, terrestrial, fossorial, or arboreal settings. Therefore, amphibians normally begin their lives as aquatic larvae, but certain species have evolved behavioural adaptations to get around this.
The young typically transition from a larval stage with gills to an adult form with lungs. Some tiny terrestrial salamanders and frogs rely solely on their skin for respiration, whereas amphibians use their skin as a supplementary respiratory surface. Although they resemble lizards on the surface, reptiles, like mammals and birds, are amniotes and do not need bodies of water to survive.
