In the article, As toid by the egg by the author Susan Gaidos, the general subject matter/theme of the article is how reproduction occurs with an egg and a sperm to create new individuals. The main ideas which will be addressed in the article are how the egg and sperm reproduce, the challenges the sperm faces to get to the egg, how the egg and the sperm have evolved over time since originally the cells looked the same, proteins are involved in the reproduction, and a discussion on reproductive failure. In Biology class we are learning about protein synthesis and this article discusses protein that help with sperm and egg reproduction.

The article was mainly about how an egg reproduces with a sperm to create new individuals. The article also discussed how at one time the sperm and egg were the same. Over time, the sperm and egg have evolved to be different. The article mentions the challenges with the sperm being able to reach the egg. There is also a discussion about how the protein affects the reproduction and a discussion on reproductive failure.

The main concepts are how the egg and sperm reproduce, the challenges the sperm faces to get to the egg, how the egg and the sperm have evolved over time, and protein affects reproduction and reproductive failure. The outer shell of the egg has a sugary compound that allows the sperm to bind to the egg resulting sometimes in reproduction. The author says “Take for example, the conflicting needs of the egg and sperm during fertilization. Sperm are in a contest to win the race to the egg. Because they’re competing with each other, they need to get there and power their way in as quickly as possible. Eggs, on the other hand, don’t want to be rushed. Bombarded with tiny, l...

... reproduction for understanding human reproduction, using computer programs and 3-D model. There has been a lot of research on how the egg binds with the sperm. The main evidence uncovered to support the main body of the article was observing the chicken reproduction to show how the egg was fertilized.

In summary, I have discussed how the sperm and egg reproduce to create new individuals. I have also described the challenges with the sperm trying to reach the egg to reproduce and how the egg only chooses the most optimal sperm for reproduction. Also, discussed how the protein affects reproduction and that they change over time since they are involved in reproduction. There is future research to gain more information on why there is sometimes reproductive failure. This new research will help a great deal in understanding why an egg and sperm cannot reproduce.

Essay Egg Shortage in Australia during Christmas Week - Australia is now facing an egg shortage before Christmas due to an outbreak of bird flu, which infected over 450,000 chickens. Producers are panicking because demand is increasing significantly due to Christmas approaching, and prices have already started to rise. A farmer even states that he is not exaggerating that the eggs this year will not be there. Why will there not be sufficient supply of eggs in the market during the week of Christmas in Australia. The relatively inelastic demand for eggs in Australia spikes during the holiday season of Christmas....   [tags: egg, bird, flu, shortage]

Evolutionary Developmental Biology Essay - Evolutionary developmental biology (evo-devo) was instituted in the early 1980s as a distinctive field of study to characterise the new synthesis of evolution hypothesis (Müller, 2007). Evo-devo is regarded as a new rule in evolutionary biology and a complement to neo-Darwinian theories. It has formed from the combination of molecular developmental biology and evolutionary molecular genetics; their integration has helped greatly to understand both of these fields. Evo-devo as a discipline has been exploring the role of the process of individual development and the changes in evolutionary phenotype, meaning the developmental procedure by which single-celled zygotes grow to be multicellular or...   [tags: Biology ] 2219 words

Essay on The Egg and the Sperm - Gender stereotypes have existed since the beginning of modern man. We've all heard them before; male dominance and female weakness, a controlled male and a flustered female, aggression and passion, and many others that all basically boil down to the same thing. Emily Martin, in her essay entitled The Egg and the Sperm, takes this problem of gender stereotype to a new and much more serious level. As an anthropologist, Martin is concerned with the socio-cultural impacts on many different aspects of everyday life, including biology....   [tags: Gender Studies] 769 words

Practical Applications of Evolutionary Biology Essay - Charles Darwin and Alfred Wallace's concept of natural selection and descent with modification helped shape the theory of evolution which holds as much weight as the theory of relativity per se. Evolutionary biology is the science devoted to understanding how populations change through time in response to modifications of their environment and how new species come into being by studying adaptation and diversity (Freeman and Herron 2004). Evolutionary biology has proved that all organisms have evolved from a common ancestor over the last 3.5 billion years....   [tags: Biology] 1498 words

Biology Essay - Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics....   [tags: Biology]

Six Marine Biology Films Essay - Summary of Films Film # 1 is called The Open Ocean. In this film, the author takes a look at the pacific. It says that the Mariana Trench (7 miles deep) is the deepest place on earth. The highest mountains of the world are located there. In shallower waters, there is much life. Photosynthetic organisms are the basis of all life in the sea. Also, some animals such as the sea anemones and the sea cucumbers allow currents to carry particles to them, and some creature pulse to deliver oxygen to their bodies, an example could be the coral polyps....   [tags: Marine Biology] 1006 words

Biology Essay - Biology 1. The virus is made up of five parts and is in the size range of 10 nm-300 nm in diameter. The first is the coat made up of protein that protects the virus to a point. Next is the head that contains the genetic material for the virus. The genetic material for a virus is DNA. The two other parts are the tail sheath and the tail fibers that are used for odd jobs. I believe that a virus is not considered to be a living creature due to the fact it is a parasitic reproducer. To me it is just like ripping up a piece of paper because it is still the same thing and it isn't carrying out any other function besides reproduction....   [tags: essays research papers] 1215 words
