Exocytosis is ana ctive transport method and does not include any transport protein. whereas calcium ions pass through the membrane with the help of trans- membrane protein. These proteins make pores inside hydrophobic membrane and allow the ions to pass though it.
Answer:
The functions of the Endoplasmic reticulum are synthesis, folding, modification, and transport of proteins.
The correct order would be:
1. A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis;
2. A caterpillar gets the carbon by eating the tree's leaves.
3. A bird gets the carbon by eating the caterpillar.
4. The bird flies into a building and dies instantly. It falls to the ground.
5. The bird decomposes and the carbon returns to the atmosphere.
The carbon cycle is very similar to the water cycle, though it has its own unique ways. Once the carbon is released into the atmosphere, it will either be absorbed by the vegetation, or go up into the higher parts of the atmosphere. If it is absorbed by the vegetation, the organisms that eat the vegetation will get it in them. When the predators eat those organism they get the carbon into their organisms. When the predators die, they start to decompose. When they decompose, the carbon is released from them and it returns to the atmosphere, and the whole process goes all over again.
