It is still being debated to on exactly when did the ancestor of our species began to walk on two legs. One hypothesis relies on a 6-7 million year old skull of Sahelanthropus tchadensis. The skull was discovered in the Djurab Desert in Chad. Since only the skull was discovered‚ it is still unclear on how Sahelanthropus tchadensis fits in our evolutionary

and children differently in various aspects of life such as intelligence‚ strength‚ ability‚ etc. Women and children have always been considered innocent individuals so we tend to be more forgiving and considerate. “This is known as the Chivalry Hypothesis‚ which states that much of female criminality is hidden because of the culture’s generally protective and benevolent attitude toward women” (Mindtap). Women are not being treated in the same manner as men when it comes to crime‚ which leads to less

M2 - Justification of Design Justify Design Decision I have placed my logo on the top right corner of my website because for me it’s the most suitable place to put logo. It makes logo visible and clear to see‚ people can easily recognize it. Many websites use the same place where I‘ve put my logo. My navigation bar is just below the shop name and the shop logo; it’s on the same place on every page‚ because that will make it easy for users to find it. For my website I have created 8 Webpages

Research Question People may think of fruit as a sweet‚ healthy option for a snack. What those people do not know is that some of those fruits can be very damaging to their teeth and to their bodies. One reason for this is that a variety of commonly digested fruits are extremely acidic. This experiment will test the pH level of everyday fruits to see how acidic they actually are. When eaten‚ which fruit will have the lowest pH (be the most acidic)? Hypothesis A sign that a fruit is acidic is

called Tucson‚ whether the simulation has an identical experience to the real Tucson is not the philosophical point. The Matrix hypothesis is the same as the metaphysics hypothesis David Chalmers claims. The metaphysics hypothesis is made up of three hypotheses. These three hypotheses are known as computational‚ creation and mind body hypotheses. The computational hypothesis “Microphysical processes throughout space-time are constituted by underlying computational processes” (Christopher Grau‚ pp137)

A researcher thinks that if expectant mothers use vitamin pills‚ the birth weight of the babies will increase. The average birth weight of the population is 3.0kg. b. An engineer hypothesizes that the mean number of defects can be decreased in a manufacturing process of compact disks by using robots instead of humans

1. The Schumpeter hypothesis links firms operating under a monopoly market structure as most important for technological innovation. Arrow‚ on the other hand‚ suggests most progress can be achieved in a perfectly competitive market. Compare and contrast these two arguments. An important issue in economics is how market structure affects innovation. In 1934‚ Schumpeter observed that some markets become increasingly concentrated‚ both with respect to innovation activities and market competition

An interesting question can produce some interesting answers. One of these is the question of what living things are made of. There are many possible answers‚ depending on who you ask. A young child asking his parents may simply be told: “Stuff”. A chemist may go into the detail of the basic common organic elements: Carbon‚ Hydrogen‚ Oxygen‚ Nitrogen and Phosphorous (Starr et al.‚ 2009) and the different compounds that are formed. As biologists‚ we tend to look at the composition of living things
