Answer:
ppss and PPSS
Explanation:
Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.
And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.
A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.
Thus, the genotypes of the parental flies in Cross 1 are
PPSS and ppss
The bond energy is defined as equal to the amount of energy given out when the bond is made (or absorbed when that the bond is broken).
So when a bond is made, and the system cools to its original energy, the amount of energy given out, -DeltaH, is more or less equal to the bond energy.
Noticed that minus sign. For a process that releases heat, DeltaH is negative.
Internet to the rescue
Hope this helps!
Answer: The answer would be Hypothesis, Experiment, Analysis of data, then lastly conclusion.
