Answer:
plasma, red blood cells, white blood cells, and platelets.
Explanation:
plasma is the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended. red blood cells have a high concentration of hemoglobin, a protein that binds to oxygen from the lungs and that gives blood its red color. white blood cells are part of the body's immune system. They help the body fight infection and other diseases. platelets are pieces of very large cells in the bone marrow called megakaryocytes. they help form blood clots to slow or stop bleeding and to help wounds heal.

Answer:
2%
Explanation:
The scientist believe that around 2% of the species that existed on Earth have been preserved in the fossil records. It is still a hot debate about it though, as there are only around 250,000 species identified in the fossil records so far, which is less than a quarter from the species that live in the present.
The reason why scientists believe that the majority of the species have not been preserved are very logical though. One of the reasons is that lot of species existed very long time ago, so their remains just didn't lasted so long. Other reason is the movement of the plates, where we have situation where plates that existed in the past have been totally suducted and melted in the mantle, while others are at the verge of it, so every fossil with them is melted and destroyed too. Another reason is that lot of species do not have hard parts, solid bone structure, so their preservation has been pretty much impossible,
