Roles of bones in bony fish include which of the following?
Rina8888 [55]

Answer:

D All of the above

Explanation:

Like our bones, bones in fish can provide general protection and support to their body.

(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)

The bone is also where the muscles will attach to, which allows for movement.

(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)

Bones can also protect the fish's brain.

(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

T cell-target cell interactions induce specialized tc cells to produce ________ that kill virus-infected target cells.
Doss [256]

The answer is granzymes. are serine proteases which trigger the apoptotic cascade in target cells. Apoptotic enzymes activated by granzymes can also destroy viruses or other cytoplasmic pathogens in the target cells so that the pathogens cannot infect nearby cells. Dead target cells are rapidly ingested by macrophages. The Tc cells also produce perforin pores to  allow granzymes to enter the target cell.
