Answer:
The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.
Explanation:
The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.
What are the differences between the three classes of Platyhelminthes?Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.
The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).
Thus, these are the differences between the three classes of platyhelminthes.

Why are streak plates used the test minerals?
A. They show you the silicon content of the minerals
B. They show you the colors of the impurities in the mineral
C. They show you the true color of the minerals
Answer: c
Explanation: correct answer
Streak plates are used to test minerals because they show you the color of the mineral in powdered form. So, the correct option is C.
What are Streak plates?Small pieces of unglazed glass or porcelain are known as streak plates, and they are used in mineralogy to assess the streak color of a mineral. They are usually a few inches in length and about an inch in width.
The streak of a mineral is its color after it has been ground into a fine powder and rubbed across a streak plate. Because some minerals have recognizable colors that differ from their actual color, it can be helpful to identify them.For example, hematite is a dark brown mineral with bright red streaks. You can differentiate hematite from other dark brown minerals by looking at the color of the streaks.
Therefore, the correct option is C.
