Placental Ruminants and Herbivorous Marsupials of Australia
The marsupial animal species that have evolved on the isolated continent of Australia are unique compared to the rest of the animal kingdom in many ways due to the harsh and distinctive environment found on the continent. The major area of marsupial biology that distinguishes them from all other eutherian mammals is their mode of reproduction. However, it can be said that there are many other areas in which unique differences can be seen between marsupials and eutherian mammals; one such area of adaptation is in the anatomy and physiology of digestion, which distinguishes them from many other similar animals worldwide.
The foregut fermenters, such as kangaroos and wallabies, evolved in regions of poor forage quality to be able to extract the most nutrients out of the poorest feeds. Fermentation in the foregut has many advantages over hindgut fermentation, which is seen in marsupials such as the koalas and wombats. The anatomy and physiology of the digestive tracts of both types of fermenters, however, are uniquely suited to their individual modes of nutrition.
It can be suggested that the foregut fermenters of the marsupials are very similar to the eutherian ruminants, as both types of adaptations are designed to increase fiber digestibility and increase nutrient absorption. However, there are many major differences between the two groups. Ruminants have developed a four-chambered stomach system, which is not seen in the marsupials, as well as a rumination cycle which allows for the rechewing of previously ingested meals. While regurgitation may be evident in marsupials, it is, however, not analogous to rumination, and is instead called “merycism.”...

One of the few differences in mink and human digestive organs is that the large intestine is much smaller in the mink and doesn’t coil around the abdominal cavity like the large intestine in a human organism. Furthermore, the size of the stomach in minks is required in order for them to eat much larger prey and be able to store more energy. The pyloric sphincter, which is useful in preventing the bringing back the food from the small intestine back into the stomach, plays a more significant role in the digestive process of the mink compared to a human. The mink and human are similarly related on an evolutionary chain.

The digestive system of the horse consists of a simple stomach, small intestines, cecum, large and small colons, rectum and anus. The horse’s stomach is comparatively small for its size. The stomach of an average horse has a holding capacity of about two gallons. This may be the reason horses eat small but frequent meals. From the stomach food moves to the small intestine, which is the main site of digestion. The small intestine empties into the cecum. The cecum; along with the large colon; make up the large intestine. Digestion in the large intestine occurs by action of bacteria and protozoa. (arg.gov.sk.ca)
...all intestine (Chiras, 2013). According to Chiras (2013), the contraction of the smooth wall of the organ pushes the feces along the large intestine. The fecal matter accumulates in the rectum, the last part of the large intestine (Chiras, 2013).
Throughout this tragedy Brutus exhibits many character flaws. He starts off by attempting to be too honorable for the adoring people of Rome. He tries to protect him from what Caesar could potentially become, a tyrant. “Wolf but that he sees the Romans as but sheep, he were no lion, were not the Romans hinds”(903). At this point Caesar has not shown any tyrannical ambition. He has been shown to be all for the people without the venture of self gain. “Thrice did I present a kingly crown and thrice did he refuse” (951). He was slightly ambitious, but what human is not? Another flaw we discover in Brutus is that he is an easily swayed man. The truculent and virulent Cassius is able to alter his perception on life especially about his people and the ambitious Caesar. Every move this confused man makes is justified by some flawed logic. This is augmented in his idiotic choice to underestimate Antony and allow him to live. “For Antony is but a limb of Caesar let us be sacrificers not butchers Caiu...

The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
In conclusion, Brutus’ mistakes and flaws are overshadowed by his honorable intentions and genuine motives. In a society littered with dishonorable, deceitful people like Antony, Brutus, with his sense of honor and integrity, contrast them all. Brutus’ greatest weakness is his tendency to believe people who script words to purposely lie or misguide him. Due to his actions, he ends up dying an honorable death of a self-suicide. Having genuine compassion and sympathy towards others is not a bad thing. However, decisions should not be so heavily influenced by the opinions of others. The significance of planning things out before doing them is clearly illustrated, as it is a way to foresee possible complications or problems that may arise. Ironically, the conspirators’ cause is for naught as Antony becomes the tyrant that they fear Caesar would have become.
In order to understand the importance of the function of dietary fiber in the diet of monogastric animals, one must first understand dietary fiber. Dietary fiber is the sum of all plant derived carbohydrates that are indigestible to digestive enzymes in the gastrointestinal tract (GIT) of mammals. The simplest definition of dietary fiber is that it is composed of plant derived polysaccharides that are not degraded by digestive enzymes in the small intestine of monogastric animals (Urriola, 2016; Hunag et al., 2016). The variation of ingredients in overall dietary fiber including crude fiber, neutral detergent fiber, acid detergent fiber, and the total dietary fiber content are what create the physiological affect in the diet of monogastrics’ such as the pig.
Companies merge and acquire other companies for a lot of strategic reasons with different degree of success. The success of a merger is measured by whether the value of the acquiring firm is enhanced by it. The impact of mergers and acquisitions on organization can be small and big in other cases.
Q1) Saliva has many important functions in mammals and birds and there are distinct differences in the salivary glands of some species. Describe the anatomical location of the buccal salivary glands in ruminants and describe the function of saliva in the ruminant digestive system. [15 marks]
In the world today, many mergers and acquisitions are happening as a result of financial losses, gaining an advantage on a competitor, increasing capabilities, and strengthening services by diversifying the products. There are numerous other reasons, but this paper will focus on the reasons indicated above.
When entrepreneurs plan their business future they will consider how they can increase their business size or profit in a short period. Entrepreneurs may consider growing their business or company by using a merger or an acquisition. These methods can be a speed up tool and a short cut to enlarge their business. (Burns, 2011) Also they can reduce competition, make it easier for entrepreneurs to think about the market and product development and risk reduction. Furthermore, some lesser – known companies can improve their firm’s image and market power by using merger and acquisition with larger firms. However, there may be risks associated with merger and acquisition related to lack of finance and time. (Burns, 2011) This essay will discuss more deeply the advantages and disadvantages of using mergers and acquisitions, showing how it can affect firms and market with the case study.
Hi there. My name is Albert and this is my adventurous story of my journey through a human. I was a delicious gourmet hamburger with fresh ingredients like salad, mustard and an angus beef pattie. I was dumped into a family feed box labelled with a massive golden arched ‘M’. Now, I’m quite an intelligent burger, unlike my other food companions and I love studying about the fascinating human digestive system when I went to Burgerton College. I’m here to tell you first-hand about my digestive journey into the human body! Here is a map of the human digestive system for your convenience to pinpoint where I am in my journey as I am recounting my story.
