The phylum Cycliophora are tiny organisms that live in large numbers on the outsides of the mouthparts and appendages of lobster

s. The feeding stage permanently attaches to the lobster via an adhesive disk and collects scraps of food from its host's feeding by capturing the scraps in a current created by a ring of cilia. The body is saclike and has a U-shaped intestine that brings it'sanus close to the mouth. Cycliophorans are coelomates, do not molt (though their host does), and their embryos undergo spiral cleavage. Basing your inferences on information in the paragraph, to which clades should cycliophorans belong? I answered it was b. Eumetazoa and Lophotrochozoa. I just have a difficult time reading the trees and I wanted to check :)
a.Metazoa and diploblasts
b. Eumetazoa and Lophotrochozoa
c. Deuterostomia and Ecdysozoa
d. Deuterostomia and Lophotrochozoa
e. Bilateria and Echinodermata

Answer:

The answer is B. Eumetazoa and Lophotrochozoa.

Explanation:

The difference between the lophotrochozoa and deuterostomia is the way they develop on the cigote phase.

Lophotrochozoa are a clase that has a spyral shape.

The literature mentions that the phylum Cycliophora are coelomates and their embryos undergo spyral cleavage which is a common characteristic of the Lophotrochozoa.

The Eumetazoa clase are conformed on organisms whit his own tissues and the phylum Cycliophora has a "U-shaped intestine that brings it´s sanus close to the mouth".

In conclusion, the correct answer is that the phylum Cycliophora gets into the clases Eumetazoa and Lophotrochozoa.

Naturally occurring solid mixture of one or more minerals and organic matter
alina1380 [7]

The naturally occurring solid mixture of one or more minerals and organic matter is known as a Rock.

A rock is a naturally occurring substances that is a solid mixture of one or more minerals together with organic matter.

<h2>Further Explanation;</h2>
  • Rocks are classified based on the chemical composition, texture and the way they are formed.  One type of rock may change from one form to another through a rock cycle.
  • Rock cycle is the process through each various rocks change from one form to another, normally an interchange between the three major types of rocks.

There are three major classification of rocks:

<h3>Sedimentary rocks </h3>
  • Sedimentary rocks are types of rocks that are formed through accumulation of sediments at low temperatures in tectonic layers and sinks. These sediments includes; pebbles, shells, sand and other material fragments.  
  • The sediments accumulates in layers and then harden into rocks over a period of time.
  • Examples of sedimentary rocks include; limestone and conglomerate
<h3>Metamorphic rocks</h3>
  • These are types of rocks that are formed as a result of changes that occurs due to intense heat and pressure under the surface of the earth. They result from action of heat and pressure on other rocks that pre-existed.
  • These types of rocks are characterized by shiny crystals, ribbon-like layers among other features.
  • Examples of metamorphic rocks are marble and gneiss

<h3>Igneous rocks </h3>
  • These are types of rocks that are formed as a result hardening and cooling of magma from volcanic eruptions. Magma may cool inside the earth or when on the surface of the earth as a result of volcanic eruptions. The lava from this eruptions cools and hardens to form metamorphic rocks.
  • Igneous rocks are glass-like and shiny with no crystals. They may also have tiny spaces and holes due to gas bubbles trapped during the cooling process.
  • Examples of igneous rocks include obsidian and basalt.
  • The three types of rocks may be further classified in terms of chemical composition, texture and formation.

Key words: Rocks, types of rocks, chemical composition
