Stages of Development - Essay Example Progesterone levels also shoot up during pregnancy and function to cause loosening of ligaments and joints throughout the body, cause internal organs such as ureters to enlarge and importantly transform the uterus to a size that can accommodate a full pregnancy. The hormones make exercise difficult because of the loosened ligaments. The woman’s posture changes, breast enlarge, abdomen transform into a convex shape increasing the curvature of her back (which may often result in changes in sense of balance). Weight gain during pregnancy slows down blood and fluid circulation. As a result, pregnant women retain fluids and experience swelling of legs, feet, hands and even face. Some women experience vision changes during pregnancy characterized by increased myopia and abnormal hair and nail growth rates. Apart from increased metabolic rates due to high demands for nutrients, women also experience taste and smell changes along with skin changes such as development of stretch marks (Fuchs, 1983). In the third week of pregnancy, gastrulation begins with the appearance of a primitive streak which establishes the long axis of the embryo. Gastrulation involves the transformation of the two-layered embryonic disc into a three layered embryo with three primary germ layers; the ectoderm (develops into the epithelial lining of the gut, respiratory and urogenital systems and associated glands), the mesoderm (develops into all tissues not formed by ectoderm or endoderm such as the muscle tissue) the endoderm (develops into structures of the nervous system and the epidermis) (Goodwin, 1994). Fertilization of the egg by the sperm results in the formation of a zygote which travels down the fallopian tube and divides into a ball of cells. The zygote continues to divide into an inner group of cells with an outer shell collectively called the blastocyst. Blastocyst moves to the uterus around day 5 and implants onto the uterine wall around day 6 for nourishment.

Discussion Questions Week One - Essay Example When applying a check and balance system in a business function, the most common approach is auditing. Outside auditors help business with inventory, expenditures, payroll, business credit cards, and so forth.

On the other hand, if an auditor does not do a good job, like in the case of Enron’s auditors they can be held accountable to state and federal law. The three check and balance branches of the government can also be useful in business. Laws, implementing the laws, and enforcing the laws constitutionally can help businesses. I would apply a check and balance system similar to the federal checks and balance system. Charles-Louis de Secondat, a French philosopher, introduced the concept several hundred years ago of separation of powers. It has been used as an example for not only the U.S., but many other democracies. The check and balance I would apply would be managerial (Executive), board of directors (Legislative), and shareholders (Judicial). These branches could execute many decisions, like the auditor brought in by the board of directors, or even a merger voted on by shareholders. The value of the checks and balance system on a business would depend on how successful the business was. Enron and WorldCom did not have a good check and balance system or they would not have gone bankrupt. On the other hand, Exxon/Mobile, IBM, and other successful companies execute their checks and balance system efficiently, hence their success. 2.
