The D blastomere is significant in the proper development of snail embryo. Without D blastomere, the larva would be imperfect. The organs like heart, shell gland, muscular foot, eyes and many more would be absent. The polar lobe of D blastomere is important in the development of these organs in snail embryo. The polar lobe has a matter that involves in the organization of dorsal ventral polarity of snail embryo.
hope the answer helps
A thumbs up would be great.
Describe the importance of D blastomere in the snail embryonic development?
Discuss the importance of embryonic induction during early vertebrate development and explain the molecular mechanisms underlying neural induction.
2. Describe the major developments of the germinal, embryonic, and fetal stages of development. Discuss two common teratogens and their effects on the developing fetus. At what point(s) in pregnancy are teratogens most dangerous?
Describe the link between the EGF receptor and Ras During embryonic development, the ability of undifferentiated cells to become various different types of differentiated cells diminishes. Describe the abilities of cells to do this during different points in human development. What sorts of factors determine what a cell is to become? If a cell is removed from an 8-cell human embryo, what is the effect on the embryo? What can be done with the cell?

Describe the process of implantation. Identify the placenta and embryonic membranes on anatomical models and describe their functions. d. e. f. Describe the fetal circulation and how it differs from adult circulation.
Describe in detail the embryonic developmental program; be sure to include the sex determination process in humans. Define homologous and analogous and explain these terms’ significance in relation to male/female genital development.
The effect of _________ on embryonic development is ___________. A. polyspermy, the embryo develops normally but is twice as large B. polyspermy, disruptive cell divisions and the early death of the embryo C. polyandry, disruptive cell divisions and the early death of the embryo D. mitosis, disruptive cell divisions and the early death of the embryo
Expression of the Hox proteins is spatially and temporally regulated during embryonic development, that is to say, the hox genes control the expression of all of the other genes involved in the development of an animal embryo Why would the hox genes be very similar from one organism to the next?
