What else can I help you with?
When the nucleus disappears during prophase it fragments into which fuse to reform the nucleus during telophase?
When the nucleus disappears during prophase, it fragments into vesicles containing membrane and nuclear pore proteins. These vesicles then fuse together to reform the nucleus during telophase.
Vesicles that will transport materials out of the cell are formed where?
Vesicles that transport materials out of the cell are formed at the Golgi apparatus in a process called exocytosis. The vesicles contain the materials to be transported and fuse with the cell membrane to release them outside the cell.
When vesicles are formed at the endoplasmic reticulum or Golgi complex and they carry particles to the cell membrane for export this is called?
This process is called exocytosis. Exocytosis is a cellular process where vesicles fuse with the cell membrane, releasing their contents outside the cell. It is important for exporting molecules and particles from the cell.
What transport process uses vesicles that fuse with plasma membrane to secrete materials into the extracellular fluid?
Exocytosis is the transport process that uses vesicles to fuse with the plasma membrane and release materials into the extracellular fluid. The vesicle membrane fuses with the plasma membrane, allowing the contents of the vesicle to be released outside of the cell.
What happens to a vesicles in exocytosis?
During exocytosis, vesicles fuse with the cell membrane and release their contents outside the cell. This process allows for the release of substances such as neurotransmitters, hormones, or enzymes into the extracellular space.
An opening formed where the two layers of the nuclear membrane fuse?
pores
What might you conclude about the membrane structure of the final vesicle formed during exocytosis and the cell membrane?
The final vesicle formed during exocytosis will have a similar membrane structure to the cell membrane, as it is produced from the cell's internal membrane systems. These membranes are composed of a lipid bilayer with embedded proteins that help regulate transport and signaling. The vesicle membrane will fuse with the cell membrane during exocytosis, allowing the contents to be released outside the cell.
When the nucleus disappears during prophase it fragments into which fuse to reform the nucleus during telophase?
When the nucleus disappears during prophase, it fragments into vesicles containing membrane and nuclear pore proteins. These vesicles then fuse together to reform the nucleus during telophase.
What layers do sperm penetrate to fertilize the oocyte?
Sperm penetrate through the zona pellucida, an acellular glycoprotein layer surrounding the oocyte, to reach the oocyte membrane for fertilization. The sperm then binds to specific receptors on the oocyte membrane to release enzymes that help in penetrating the oocyte membrane to fuse with the oocyte.
Do vacuoles fuse with other membranes?
Yes, they do. They have to fuse with the cell membrane to "dump" their contents.
What gas is formed when hydrogen atoms fuse?
The gas formed when hydrogen atoms fuse is helium. Stars do this.
Scientific evidence suggests that magnesium is formed by stars during?
Scientific evidence suggests that magnesium is formed by stars during nuclear fusion processes in their cores. As stars undergo fusion reactions, elements like helium and carbon fuse together to create magnesium through successive nuclear reactions. These elements are then released into space when the star reaches the end of its life cycle.
What element is formed when hydrogen nuclei fuse together?
When hydrogen nuclei fuse together, they can form helium. This fusion process is the energy source for stars, including our sun, where hydrogen nuclei combine to form helium through a series of nuclear reactions.
Vesicles that will transport materials out of the cell are formed where?
Vesicles that transport materials out of the cell are formed at the Golgi apparatus in a process called exocytosis. The vesicles contain the materials to be transported and fuse with the cell membrane to release them outside the cell.

This process is called exocytosis. Exocytosis is a cellular process where vesicles fuse with the cell membrane, releasing their contents outside the cell. It is important for exporting molecules and particles from the cell.
When two or more nuclei join together or fuse?
nuclear fission
What does nuclear fusion mean?
Nuclear fusion refers to a nuclear reaction wherein two light nuclei fuse to form a heavier nucleus. This process releases energy.
