Which plane would be helpful when viewing the heart and the right kidney at the same time? whychose that plane and why the remaining planes would not be helpful when viewing these specific organs at the same time. Enzymes are important during the process of fertilization. What would be the anticipated consequences if the level of acrosin was low or non-existent in the acrosome? What is the name of the outer cell layer of the blastocyst and what does it give rise to? Does this layer contribute to the development of the embryo?

ARRANGE THE FOLLOWING EVENTS IN CORRECT SEQUENCE from 1-13: Penetration of the zona pellucida Cortical reaction 1st cleavage Acrosomal membranes rupture, and release their enzyme contents Penetration of the corona radiata Depolarization of egg membranes Migration of cortical cytoplasm to form gray crescent Sperm attach loosely on the zona pellucida Zona reaction Oocyte completes meiotic division ZP3 tenaciously binds acrosome-intact sperm Release of Ca+2 in egg cytoplasm from its bound state Amphimixis
Internal genitalia like the vagina, uterus, and ovaries in females, and the testes, epididymis, and vas deferens in males, originate from the Mullerian and the Wolffian ducts respectively. These two ducts are both present in the same fetus during the early phase of human development, but one will prevail over the other to make the developing conceptus a female or a male. If both persist, the baby will have an intersex condition. Discuss two syndromes that are examples of disorder of sex development (intersex condition), and how they will affect the future life of the newborn
