Cells synthesise a large number of different macromolecules required for life. The Golgi apparatus is integral in modifying, sorting, and packaging these substances for cell secretion (exocytosis) or for use within the cell. It primarily modifies proteins delivered from the rough endoplasmic reticulum, but is also involved in the transport of lipids around the cell, and the creation of lysosome.
<span>Enzymes within the cisternae are able to modify substances by the addition of carbohydrates (glycosylation) and phosphate (phosphorylation) to them. Proteins are also labelled with a signal sequence of molecules which determine their final destination. For example, the Golgi apparatus adds a mannose-6-phosphate label to proteins destined for lysosomes. </span>
<span>Vesicles which leave the rough endoplasmic reticulum are transported to the cis face of the Golgi apparatus, where they fuse with the Golgi membrane and empty their contents into the lumen. Once inside they are modified, sorted, and shipped towards their final destination. As such, the Golgi apparatus tends to be more prominent and numerous in cells synthesising and secreting many substances: plasma B cells, the antibody-secreting cells of the immune system, have prominent Golgi complexes. </span>
<span>Once the proteins reach the trans face, they are placed into coated transport vesicles and bud off to reach their final destinations. The form of the vesicle is determined by the type of protein and the label it acquired.</span>

Explanation:
Hey, there!
The eco-system consists of various type of organisms in tge ecosystem. The all type of organism as producer, decomposer, consumers live in ecosystem.
Three adaptations of organism are:
- By losing and gaining of organs: Some of the animals lose their organs to survive in some places like yak have more hair to survive in cold places.
- By changing the colour of body: Some animals such as grasshopper changes their colour to survive in places.
- By modification of organs: some animals modify their organs to survive such as legs and beak of ducks are modified to survive in swim and search foods.
The importance of adaptation are:
- It helps organism to live a longer life.
- The adaptation helps to make an organism fittest to any environment.
- The adaptation helps an organism to search foods and live their life.

6 seconds - 1 second = 5 seconds for (1 breath)

T<span>he least likely to be a source of genetic variation among living organisms is D. asexual reproduction. Asexual reproduction is a kind of reproduction that does not include fertilization process of two gametes: female and male but only includes parts of plants or cells. In this case, variation is minimized</span>
