pores
A zygote where the nuclear content is diploid
The vesicle fuses with the cell membrane, releasing it's contents.
Which sentence best describes exocytosis? A. a vesicle fuses to a lysosome and its contents are destroyed B. a vesicle fuses to the cell membrane and its contents enter the cell C. a vesicle fuses to the cell membrane and its contents leave the cell D. a vesicle fuses to the nuclear envelope and its contents enter the nucleus? Exocytosis is the durable, energy-consuming process by which a cell directs the contents of secretory vesicles out of the cell membrane into the extracellular space.
Yes, two vesicles can fuse. When one vesicle fuses with another one or with part of the cell membrane this is called vesicle fusion.
Yes. I have seen a paragraph on a Biology guide book. It said: In plants, a cell plate is formed as vesicles containing cell membrane materials fuse together along the equator of the cell. Once the cell plate has fused with the plasma membrane and the two cells are completely divided, cellulose is secreted to form the cell wall.

Yes, they do. They have to fuse with the cell membrane to "dump" their contents.
The gas formed when hydrogen atoms fuse is helium. Stars do this.
Yes, all organelles within the cell are bound by membranes that are all made up of the same basic structure but have different kinds of proteins within them that allow them to have a distinct cellular function. These membranes are always in exchange with one another as well, things called vesicles will bud off from one membrane and fuse with another to deliver things from one organelle to another. So for example the nucleus is bound by the nuclear membrane and the cell is bound by the plasma membrane. Parts of the plasma membrane can bud off to form a vesicle, basically like a bubble and can travel to the nucleus (or any other organelle) where it will fuse with the nuclear membrane (or the membrane of the particular organelle) and deliver its contents into the interior of the organelle or simply deliver new membrane to that organelle. There is an entire branch of scientific research that is concerned with understanding how this whole process works and how membranes bud and form vesicles and fuse, and what is contained within the different membranes of the different organelles, its called membrane trafficking. Hope that helps!
nuclear fission
A zygote where the nuclear content is diploid
Nuclear fusion refers to a nuclear reaction wherein two light nuclei fuse to form a heavier nucleus. This process releases energy.
Sedimentary rock is formed when many rocks are broken into small pieces by erosion, after a long time the small rocks fuse together and become a rock with many different layers.
fission: nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller partsfusion: nuclear fusion is the process by which two or more atomic nuclei join together "fuse"

the wall. it is necessary to only let things in and out based on what the nucleus of the cell wants. for example the cell membrane will only let sperm in until one has penetrated the egg, then the membrane stops trying to let sperm in.
