- Differentiated cells in a developing embryo derive from________.a. endothelium, mesothelium, and epitheliumb. ectoderm, mesoderm, and endodermc. connective tissue, epithelial tissue, and muscletissued. epidermis, mesoderm, and endotheliumIn adults, new connective tissue cells originate from the Ectoderm O Mesenchyme Endoderm MesodermA gland that secretes substances by exocytosis is a(n)___________ gland.a. merocrine b. apocrinec. holocrined. mammary
- Tissue that contracts and is striated and involuntary would most likely be found in (a) the leg (b) the wall of the stomach (c) the exocrine glands (d) body structures requiring very rapid contraction (e) the heartMost neural tissue is derived from ectoderm. This statement is (T/F). • If true, enter x in the blanks below. • If false, then how would you change the sentence to make it correct? You can change two words at most. Changes that just reverse the meaning (e.g. changing "is" to "isn't" or "all" to "none") will not earn credit. I would change the word(s) to the word(s) to make the sentence correct.The mesoderm eventually turns into which of the following substances? O connective tissue gut lining O skin, nervous tissue O bone O A and D
