Sorry but no.
It is hard to improve on Mick's explanation, but maybe this will help.
In the strict scientific sense, a hypothesis is simply a conjecture, hopefully phrased so as to be both testable and falsifiable.
It is never proven nor disproven, only supported or unsupported by evidence.
Think of hypotheses as little testable bits that contribute to framing a theory.
No hypothesis can ever become a law, although a theory, in principle, could.
A law, in the scientific sense, is a simple, immutable, mathematically definable relationship between specific variables that never changes.
Most scientific laws pertain to physics - not biology.
