What does membrane - bound sacks means?
When substances are too large to pass through the cell membrane directly (they'd leave a gaping hole), they are enclosed in a lipid sac that is similar in composition to the cell membrane. Instead of punching through the membrane, the sac merges with it allowing the large substance to exit the cell without damaging the membrane.
What are the holes in the mitochondria of an animal cell called?
They are not holes.They are membrane proteins.
Why does cell membrane not leak when its is punctured with a needle?
If a cell is punctured with an ultra-fine needle it will NOT leak. instead, the proteins and phospholipids will move in to fill the gap as the needle is removed.
If a tiny hole is made in a plasma membrane it usually heals immediately and no harm results What property of the plasma membrane allows this?
The plasma membrane forms the external boundary of the cytoplasm of a cell. The fluid property of its lipid bilayer allows a tiny hole to heal.
What happens when the cell membrane or plasma membrane ruptures or breaks down?
On providing a hypotonic environment outside the cell, the plasma membrane bursts. When the cell membrane ruptures, the cellular contents are released to the environment as the cell membrane is the 'wall' that separates the cellular contents from the outer environment. In biological terminology, this is called cellular lysis.
What is the minute hole in nuclear membrane?
nuclear pore.
What is the openings in the nuclear membrane?
pores
Is DNA the same as a nuclear pore?
DNA is cause of nuclear pore (hole between two nuclear membrane) appearance. The single-stranded DNA located in pore annulus initiate nucleoporins assembly building native structure of pore complex ( please see details in Kuvichkin V.V., 2011, J. Membr. Biol. v. 241(3), pp.109-116).

What is it called when a virus attached to host cell injects its nucleic acid into the host cell then makes more viruses?
Attachment, or adsorption, occurs between the virus and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where viral reproduction may begin.

Why does poking a hole in a cells membrane kill the cell?
The inside of a cell is an extremely controlled environment; the organelles inside are extremely fragile. Breaking open the membrane that controls the in/out flow of chemicals around the cell allows foreign objects to get inside the cell, causing damage. It also allows the cytoplasm to leak out, separating organelles.

What is the protein that punches hole into the plasma membrane of a infected host cell called?
What is the infective organism?In H.pylori its the type IV secretory system.
Can a black hole be destroyed be a Nuclear missile?
No
