Which worm sometimes uses specialized tentacles to exchange gas and capture food?

            There are marine worms who possess tentacles which are used for exchange of gases (taking in oxygen and letting out carbon dioxide) and for capturing food.

Example:

            Spaghetti worm is about 12 to 24-inch long found deep in the coral reefs. They possess feeding tentacles that reaches to 3 feet long. They are bluish white sometime pink or purple in colour. Once spaghetti worm finds something to eat on ocean floor, they send out feeding tentacles capture food and bring it to mouth.  

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
