It is often said that biology, chemistry and other high-level sciences cannot be

It is often said that biology, chemistry and other high-level sciences cannot be reduced to physics, e.g. laws governing evolution are irreducible to anything on offer in physics. On the other hand one often reads in descriptions of what a deterministic world would look like something akin to this: If one has a complete description (of every particle) of the universe at time t and knows all the physical laws that govern it, then one could at least in principle deduce the state of affairs obtaining at another time t2, where t2 could either be a future or past point in time. Since causation is a debated concept, I take it that that the main aim of scientific theories is prediction rather that (causal) explanation. But how can we reconcile the fact (?) that higher-level sciences cannot be reduced to physics and with this common description of determinism.
