Essays on Embryology

The purpose of this paper is to review the article, “Was Darwin Wrong?”, by David Quammen (2004) and to offer some discussion at the end of the paper. The main thrust of the Quammen’s article is to provide a description of the current and past evidence that supports Darwin’s theory of evolution through natural selection.

For reproduction to occur, all these parts play an important role. The stigma is the female part of a flower that receives pollen grains. It normally has a sticky surface to enable pollen grain to stick and germinate on it. There are several shapes of the stigma. The different shapes enable them to be well adapted to their role in reproduction. Some of the shapes ...

When an oocyte and spermatozoa fuse, the process is referred to as fertilization. The gametes are haploid at that stage and grow further into a diploid zygote. There is a difference in the forms that the process can be made possible. It can be through the natural mode that occurs in vitro or can happen outside the body in vivo (Hill, 2016). Research studies have been done adequately to ensure that circumstances that support life out of the womb can be created for a while before a transfer is done to the womb for future growth and development. For ...

Ans1: Growth is defined as the increase in size and mass of a particular organism over a period of time. It is measured in terms of biomass (mass of the organic material). An organism grows by mitosis. Growth stops after certain age of the organism. Growth is quantitative and measured by taking the measurement of height, weight, size and shape of body organs like brain, etc . Development is defined as the process of cells differentiation which helps in the development of the body. It adds complexities to the body (such as organ development). Development of the organism is a ...

“Unless and until it can be proven that the unborn child is not a living entity, then its right to life, liberty, and the pursuit of happiness must be protected.” (" Reagan, “Evil Empire,” Speech Text").
