During vesicles in the cell fuse with the cell membrane, releasing their contents to the outside.

During exocytosis, vesicles in the cell  fuse with the cell membrane, releasing their contents to the outside. 

It involves the movement of an intra cellular  vesicle  to the plasma membrane, then fusion.

There are many cellular processes that involve exocytosis. These include:

1.release of neurotransmitters from presynaptic neurons

2. secretion of enzymes, peptides hormones and antibodies from cells.

3. Placement of integral membrane proteins

4. Antigen presentation during an immune response.

5. acrosome reaction during fertilization.

6. Recycling of plasma membrane bound receptors

The scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )
