In wild, tigers eat all parts of their prey. including bones. in zoos they develop bone problems when they are fed only flesh? why?

(This is my personal idea, I'm not sure if it's correct, but it's just what I think)

In wild, tigers eat bones in order to get calcium.  This is one of two main elements of bones, and it ensures the bone is  hard enough to carry the whole weight of the animal. The diet they have in the zoo doesn't contain bones, so the bone problems are due the lack of calcium. To solve the problem, zoos need to provide the tigers some bones in their diet so as to ensure that they get enough calcium

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

i think its white blood cells

i hope this
