How does the concept of 'epigenetics' challenge traditional Mendelian genetics regarding inheritance?

It proves that acquired characteristics cannot be passed down

It refutes the existence of genes altogether

It suggests all traits are solely determined by DNA sequence variations

It demonstrates heritable changes in gene expression without altering DNA sequence

Which principle of fluid dynamics describes the relationship between the speed of a fluid and its pressure, stating that faster-moving fluids exert lower pressure?
