The larval form of Schistosoma mansoni gains entry into the intact skin with the help of the <u>proteases enzyme</u>.
Explanation:
Parasitic worms, also known as Helminths, are eukaryotic multicellular parasites. These parasites produce certain molecules that help them to enter into the tissues of the host cell.
Example of a parasitic worm is the larval form of Schistosoma mansoni parasite. The larval form of this parasite is known as miracidium. The miracidium causes schistosomiasis or snail fever.
<u>The miracidium gains entry into the intact skin with the help of the proteases enzyme, which the degrades the proteins of the skin.</u>

If one of the party does not understand the message that is been relayed or feel that the other party is not taking enough caution to avoid collision, then he should sound the five short blasts to signify that he does not understand what the other party is trying to do.
