Answer:
The two enantiomers of dopa have very different shapes, even if they have the same number of atoms of each element involved and have the same ones connected to one another. The great difference in activity shows that the key thing in determining biological activity is shape, not merely the number or arrangement of atoms.

The correct answer is A. Homologous chromosomes with heterozygous alleles.
If the alleles of genes are different then the scientist is observing for homologous chromosomes with heterozygous alleles.
In each homologous pair there is one chromosome which comes from maternal chromosome and the other one from paternal chromosome.
Homologous chromosomes are not identical but they are similar. Alleles for each homologous chromosome is not same but genes are the same.
You can use scientific inquiry to answer the questions 'Why is the sky blue?' and 'Why do diseases exist?' because science can help you explore and prove them while you can't prove, at least not in this way, why bad things happen... ☺
I believe that the answer is Cells or carbon.
Answer:
They are pulled to opposite sides of each other. During anaphase, sister chromatids (or homologous chromosomes for meiosis I), will separate and move to opposite poles of the cell, pulled by microtubules. In nondisjunction, the separation fails to occur.

Hope this helps! Good Luck !! :)
