What are the examples of acoelomate animals?
Flatworms, such as tapeworms and planarians, are examples of acoelomate animals. These animals lack a true body cavity called a coelom and have a solid body structure instead.
What type of animals have no body cavity?
Lower phyla in the animal kingdom such as Cnidarians, Porifera, and Ctenophora.
Do flatworms have no coelom?
Yes, flatworms do not have a true coelom. They have a solid body structure without a cavity between their gut and body wall, which distinguishes them as acoelomates.
Explain how bone cells embedded in a solid ground substance obtain nutrients and eliminate waste?
Osteocytes are mature bone cells surrounded by matrix which solid bone cell ground substances attach to. Bone cells are in the proximity of blood vessels, just like any other cell in the body. Bones only have cells in their growth areas and in the bone marrow, where blood cells are also produced.
What are solid substances that are nutrients?
solid subtanses are the solid stuff
What are the solid and liquid component blood?
The solid components of blood are red blood cells, white blood cells, and platelets. The liquid component is called plasma, which carries these cells, nutrients, hormones, and waste products throughout the body.
Flatworms have layers of tissue that surround the gut and organs in one solid body they are?
Flatworms are triploblastic organisms, meaning they have three germ layers (ectoderm, mesoderm, endoderm) that give rise to different tissues in their body. This allows them to have specialized structures like muscles and nerves. They have a solid body shape, lacking a body cavity or coelom.
Why liquid portion of blood is slightly greater by volume than the solid portion?
Blood is more liquid than solid because it has to travel through small passage ways. If more solid material is present in the blood, it would solidify and the organism would die because no nutrients could be transported to its cells.
What blood cells make up the solid part of the blood?
Blood has red cells and white cells, but I'm not sure what is meant by 'solid part'.
What is a solid ball of cells?
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
What makes up the solid portion of the blood?
Cells make up the solid portion which is 45% of the blood. red blood cells, hemoglobin, whiteblood cells, and platelets.
What are the three solid components of the blood?
The three solid components of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
