Answer:
The reason why these stars seem so small compared to our Sun is:
B) Our Sun is much closer to Earth than the Seven Sisters.
Explanation:
The reason behind this is that the sun is at a distance of the earth of 0.000016004 light-years. While the seven stars are at a distance of 400 light-years. Making them so far away that their size is reduced because in physics object size is altered by the perspective of the watcher or observer. Meaning that a ball the size of a car can be seen by our eyes as small as a bean if it is at the proper distance.
Giemsa stain shows the staining of centromeres.
- C-banding, which involves denaturing the chromosomes in a saturated alkaline solution followed by Giemsa staining, is a technique specifically used to identify heterochromatin.
- Different banding methods can be selected when identifying chromosomes. Chromosome banding is an important technique used in chromosome karyotyping to distinguish between normal and defective chromosomes for clinical and scientific purposes.
- The most common dye-based chromosome banding methods are Giemsa (G), reverse (R), and centromere (C). G-banding stains trypsinized chromosomes, whereas R-banding uses hot acidic saline to denature the chromosomes prior to Giemsa staining.
- It contains a significant amount of AT-rich satellite DNA. Just as G-banding represents AT-rich sections of chromosomes, so does Q-banding.
Therefore, centromeres is the correct answer.
