Has one extra chromosome in each cell (i.e 47 instead of 4.6). This is caused by one of the cell divisions during the formation of sex cells. Basically, the 21st chromosome ends up with 3 chromatids instead of 2. This is also why down syndrome is called trisomy 21.

Irina-Kira [14]

Answer:

c. Proteins and lipids are made on the ER membrane and put in vesicles.

a. Vesicles containing proteins and lipids fuse with the Golgi bodies.

d. The Golgi bodies tag the molecules to signal their ultimate delivery.

b. Vesicles pinched off from the cristernae carry the molecule to its location.

Explanation:

Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
