Note about the question:
You will find the pedigree in the attached file
Answer:
The boy and the girl represented by solid black-colored square and circle, respectively, are affected with sickle cell anemia
Explanation: A pedigree tells information about the phenotype of individuals in the family. There are certain symbols to take into count when analyzing a pedigree. Among many others, a few to consider in this particular problem are
- Squares that represent males
- Circles that represent females
- White shapes that represent healthy or normal individuals
- Black shapes that represent affected individuals
The affection in this problem comes from the paternal line. Susan´s husband is affected by sickle cell anemia. His mother and his grandmother are also affected.
Susan is a healthy woman. They had four children. Two girls (circles) and two boys (squares).
From this last generation, one of the girls (black circle) and one of the boys (black square) are affected.
I believe the answer would be "Vestigial Structures". Hope this helps.
Its definitely not A or D because there are 26 weeks in 6 months.

Cell X is the only cell that has chloroplasts, a pigment found in leaf cells of plants / sometimes other parts may have too. Animal cells almost never have chloroplasts
Answer:
In Eukaryotes, The DNA is so long that it needs to be super coiled to get fit inside the cell.
This process is required in both Eukaryotes and prokayotes. The super coiling and packaging using the DNA binding proteins allows the lengthy molecules to fit inside the cell.
The DNA in the bacterial cell is arranged in several super coiled forms. The over winding of DNA is prevented in bacterial cell by the help of an enzyme known as DNA gyrase which is a type of topoisomerase.
