I don't have your lab observations, but I can give you the reason why refraction occurs.
Refraction refers to the bending of light at the interface as it passes through mediums of different densities.
Refraction occurs because light travels at different speeds in mediums with different densities.
Hope this helps!
<span>The control group would not receive any medication or they would be given the salt solution without any drugs with it (basically a placebo).
A dependent variable is a variable dependent on another variable: the independent variable. In simple terms, the independent variable is said to cause an apparent change in, or simply affect, the dependent variable.
The variables you have are what the rats are feed (their diet), number in cage, size of the cage (things such as a smaller care with more within it should cause undue stress), what they are exposed to within their environment. Even things sun as amount of light within the room, the temperature of the room, etc. </span>
Answer: 
dominants and 
recessive.
Explanation:
Mendel's monohybrid cross is definied as
- a genetic combination of two homogeneous genotypes.
- One is <em>dominant(TT)</em> to other <em>(tt-recessive).</em>
Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)
Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)
[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]
The results in the F2 generation after a monohybrid cross: dominants and recessive.
kidney - removes urine from the body by making urine
urethra - leads urine from the body
bladder - stores urine until it is ready to be released
ureter - leads urine away from the body
