B and C ANSWER...
B) they are only present on the endoplasmic leaflet of the cell
C) they are only present on the cytosolic leaflet of the cell
Answer:
Homeostasis
Explanation:
Cell membranes enable organisms to maintain homeostasis by regulating the materials that may enter or leave a cell.
Full question:
Several parts of an animal cell are involved in the processes of protein synthesis, packaging, and export. Which of the following correctly places the cell parts in the order in which they are involved?
- nucleus → vacuole → cell membrane
- mitochondria → vacuole → cell membrane
- ribosome → endoplasmic reticulum → Golgi complex → cell membrane
- lysosome → endoplasmic reticulum → Golgi complex → cell membrane
Answer:
ribosome → endoplasmic reticulum → Golgi complex → cell membrane
Explanation
First, the DNA is transcribed into mRNA in the nucleus. The mRNA then moves to the cytoplasm. Here, it encounters the ribosomes.
At the ribosomes. the mRNA is translated into protein. It gets folded in the endoplasmic reticulum and then is transferred to the Golgi complex.
At the Golgi complex, proteins are modified, packaged, and transported to their destination in a series of vesicles, which if it is outside the cell, is the cell membrane.
Primary succession occurs in an area that has not been previously inhabited by a community. Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows.
