Answer: b. have cartilage skeletons
Cyclostomata is a group of Agnatha class. It comprises of jawless fish species like lampreys and hagfishes. They have jawless mouth, epidermal structure that function as teeth. The name Cyclostomata suggests round mouth. The fertilization and development in these fishes is external to the body and the offspring do not get the parental care. These animals are cold blooded and exhibit a cartilaginous skeleton. They have two chamber heart. They feed on other fishes and mammals.
The two body systems work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste products may include the respiratory system and the circulatory system.
The body system may be defined as a group of organs that work together to perform a specific function. It significantly involves the collection of several body parts that are able to work together in order to serve a common purpose such as growth, reproduction, and survival.
The respiratory system works together with the circulatory system in order to provide this oxygen and eliminate the waste products in the form of carbon dioxide to facilitate the complete metabolism. The lungs and respiratory system allow us to breathe. It brings oxygen into our cells through the blood which is part of the circulatory system.
Therefore, the respiratory system and the circulatory system are the two body systems that work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste products.

-igneous to sedimentary
-metamorphic to sedimentary
-igneous to metamorphic
-sedimentary to metamorphic
-metamorphic to metamorphic
Answer:
All are correct
Explanation:
An igneous rock can be converted into sedimentary rock when it is exposed to the surface because only then it will start decomposing by the action of water and wind
In the same way a metamorphic rocks on being exposed can be broken down into sediments
An igneous rocks can be converted into metamorphic rock when it is buried deep into the Earth crust at high temperatures and pressures
Sedimentary rocks become metamorphic only when they are subjected to heat and pressure from burial.
And lastly Metamorphic rocks of one form can be converted into metamorphic rock of other form.
Hence, all the given changes are correct
b. Scanning electron microscope
c. Compound light microscope
