When it is said that mutation is the ultimate source of genetic variation it means that it creates several new combinations which is similar to meiosis and fertilization because <span> new alleles and genes appear. It is just about some common points.</span>
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.

The ozone layer is a stratospheric region composed of Ozone (Triatomic Oxygen)
CFC´s (Chlorofluorcarbons) are broken down by ultraviolet radioation to release chloride ions wich react with ozone breaking it down into oxygen.
One chlorine atom can destroy 100.000 ozone molecules - smallamounts of CFC can break down large amounts of ozone.
The thinning of the ozone layer by CFCs reduces the absorption of UV light in the stratosphere
