True.An operon is a prokaryote. Its is a group of genes working together to make a specific protein.
The structures that annelids use are palps, antennae, eyes, statocysts, nuchal organs and lateral organs.
I hope this helps.
Fusion and gravity
Fusion and gravity keep the sun from blowing itself up. A large amount of energy is released by the
sun. Protons are fused together to form helium atoms due to the high heat and
pressure at the center of the sun. The Sun does not blow itself up from the
outer pressure of nuclear fusion in as much as the inner force of gravity
balances it.
