Answer:
a. Centromere
A centromere is a specialised DNA sequence of a chromosome that links pair of sister chromarids (a dyad)
Answer:
Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.
Explanation:
The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.
The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.
Thus, the correct answer is option (d).
You would want this observation to be in an area with a lot of biotic and abiotic factors, so the best place for it is an ecosystem.
Answer:
During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of the cell.
