- 6) In the cnidarians, Choanocytes, the cells responsible for filtration, are located in the ectoderm. The cnidocytes, located in the endoderm, are the cells specialized in capturing prey. Cnidocysts, located in the ectoderm, are the cells specialized in prey capture. Choanocytes, located in the ectoderm, are the cells specialized in prey capture. The cnidocytes, located in the ectoderm, are the cells specialized in prey capture.1. What would be the effects if metamerism is absent in annelids? 2.

- 1. In Deuterostomes, nutrient molecules (monomers) are taken into the space between the endoderm and the ectoderm because a) the ectoderm makes protein for movement, b) the endoderm cells release hydrolytic enzymes that act on polymers, c) the endoderm releases enzymes that carry out dehydration synthesis of proteins. d) mRNA polymerase causes transcription. e) all are correct. 2.The Amoeba cell exhibits specialized abilities that enable it to react to a stimulus by producing a response or a behavior. It can do this because it has adapted properties exhibited by simpler more primitive cells. These cellular properties include a) Separation of the fluid environments inside and outside the cell. b) Active transport of Na+ out of and K+ into the cell, c) diffusion of Na+ in to and K+ out of a cell in reaction to a stimulus, d) the stimulus interacting with a receptor site in a membrane embedded protein, e) All of these are true.-4. In the diagram below, the stages of development in a frog embryo are NOT arranged in the correct order. In what order should they be placed to show the normal sequence of development in the embryo? What process is occurring in this diagram? B. D Dorsal lip of blastopore Dorsal lip of blastopore Dorsal lip of blastopore Dorsal lip blastopon54. In protostomes and deuterostomes, the space between the endoderm and the ectoderm is important because: a) it provides a perfect environment that can be maintained for all the cells even if the outside environment change b) protostomes use their ectoderm to develop digestive organs inside it c) deuterostomes develop their brain from the mesoderm in this space d) the endoderm forms the immune system in this space, e) all are important.
