The rhynchocoel is a ________.
Anastasy [175]

Answer:

fluid-filled cavity

Explanation:

Rhynchocoel is a fluid-filled tubular cavity present in the organisms of the phylum Nemertea. This cavity lies above the intestines of these organisms in the lower body.

Nemertea is a phylum composed of worms that can be found in shallow water.

These worms have already been classified as a branch of the Flatworms (such as Planarians), with which they are often confused. But recent embryological and molecular evidence points to a phylogenetic relationship with mollusks and annelids. They remind the Flatworms to be non-segmented flat worms. But unlike these, they have a complete bowel with mouth and anus, and a closed vascular system. The article on Planarians can be accessed here.

Anastaziya [24]

The purpose of a vortex instrument is to mix "small vials of liquids" in a laboratory.

Explanation:

A vortex instrument or a mixer is an laboratory instrument which is used to mix liquids in small vials.

The term vortex means swirling of a mass of air and this instrument also mixes liquid through swirling movement inside a tube.

A vortex unit is run by an electric motor which moves a rubber cup attached to the drive shaft.

The rubber cup swirls or oscillates in a circular motion and when a test tube with the liquid is pressed in the cup, the liquid contents get mixed through the transmission of the circular motion from the cup to the liquid. The speed of the rotation can be controlled.
