Why did scientists struggle for thousands of years to accurately describe the solar system?

hey there answer is wrong

Explanation:

s its that the planets appeared to be moving backwards. i got the answer right plus look it up if you dont belive me, and that wasnt even an answer choice.

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

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
