A mesoderm is a middle layer of the zagote(one of three layers)
From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.
no
yes, I think it's called coelom. An organism with a true body cavity is called a eucoelomate. This means that the body cavity exists between the inner layer of mesoderm and the outer layer of mesoderm. A pseudocelomate kind of has a body cavity but it is the space between the endoderm and mesoderm. This is not a true body cavity because it is not mesoderm on mesoderm.

Mesoderm, specifically the visceral mesoderm layer consisting of mesoderm and endoderm.

The three systems that developed in the mesoderm of the planarians are ectoderm, mesoderm, and endoderm. They are usually described as the three germ layers.

mesoderm The mesoderm forms: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood (lymph cells), the kidney, and the spleen.
The chordamesoderm is the part of the mesoderm (one of the 3 germ layers in a developing embryo) that gives rise to the notochord.

The heart is derived from the mesoderm, along with skeletal muscles and some other body organs.
no, its the mesoderm.
