The purpose of this study is to understand the feeding rate of Daphnia magna. D. magna is a species of Daphnia that belongs to the suborder Cladocera (Ebert, 2005). They live in freshwater and feed on small, suspended particles in the water. They are filter feeders. Phyllopods, which are leaf-like appendages, provide a filtering apparatus for the collection of food. These structures beat to produce a constant current of water, allowing particles to be filtered by fine setae on the thoracic legs. The particles are then transferred to their mouth groove to be ingested. D. magna typically feed on planktonic algae (Ebert, 2005). The following experiment uses algae to test what affects the feeding rate of D. magna. The rate of filtration is dependent on multiple factors including temperature, food density, body size, and water pH.…
The popular name for Daphnia is ‘water fleas’ because they resemble fleas in shape and movement. Unlike fleas, which are insects, Daphnia are crustaceans classified under the scientific order, Cladocera. The purpose of this experiment was to examine the alertness of Daphnia ambigua alertness at different temperatures. It involved the incubation of 30 Daphnia ambigua in three 100ml beakers. Exposing each beaker to a different temperature revealed that temperature of the surrounding environment had a significant impact on the alertness of the Daphnia. The control group for this study was the Daphnia placed at room temperature i.e. 22° Celsius. The experimental groups were the ones placed at 5° and 28° Celsius. The constant variables were food…
This will depend on the number of microscopes you have and access to a healthy culture of Daphnia. Students can readily follow this procedure working in pairs. Because of the variability of results between individual Daphnia it is not appropriate to make conclusions from one set of results, so each pair (or group) of students should carry out more than one investigation to contribute to the class set.…
2. What might be suggested by the fact that Oedipus had to send twice for Teiresias?…
Aeolus and the Aeolian Bag could have been avoided if Odysseus has inspired a shared vision and encourage the heart. Like the text mentions, leaders cannot expect commitment if you are not putting in the effort to encourage it. (Kouzes and Posner 2014, p. 17) If Odysseus had been more transparent about his decisions, his crew would have been committed to him and probably trusted the fact that he would not save treasures for himself. Odysseus must have not been good about recognizing his crew’s contributions for them to distrust him and open the bag full of wind. Odysseus should have done better at showing his appreciation and recognizing individual successes. (Kouzes and Posner 2014, p. 22)…
Phaethon was the son of the God Helios, who drove the chariot of the sun, but he lived with his mother, the gentle Clymene, in a beautiful valley in the east. However, his companions did not trust him that his father was the Sun King. He bravely began to climb the unused path which led to the palace of the sun in order to prove that he was indeed the son of Helios. Helios let Phaethon ask any gift he wanted so as to put an end to his doubts. To Helios’s surprise, Phaethon quickly said,” Oh, my father! Let me drive the wonderful golden chariot of the sun, which was my greatest desire in my heart, for just one day.” Helios refused, because Phaethon has neither the strength nor the wisdom for the great work. Nevertheless, Phaethon…
Apollo has many attributes, but he wasn't originally the chariot-riding sun god Helios. He was god of prophecy, healing, music, archery, light, and truth, the twin brother of Artemis (Greek) or Diana (Rome) who became associated with the moon.…
Alexander, son of king Philip II and Olympias was born in 356 B.C.E, and at age 19, became king of Macedon. With a great army at his disposal and his brilliant military mind, he started his conquest. From 337-323 B.C.E Alexander conquered Greece, Egypt, Mesopotamia, and a large part of Asia. Alexander ruled from Macedonia to the northern part of India. He defeated the Persians numerous times with his incredible military strategies, even when his armies were outnumbered by almost 200,000 Persian soldiers. The sheer size of his empire was unlike anything ever seen before but when he died in 323 B.C.E, the three main areas he conquered (Greece/Macedonia, Egypt, and Mesopotamia/ Asia) were split up and became their own kingdoms. The area that was once Greece and Macedonia became the Antigonid Kingdom, the Egyptian are became the Ptolemaic Kingdom and the Asia/ Mesopotamia area became the Seleucid Kingdom.…
The Teaching Theology and Religion Journal published a peer-reviewed article in April 2014 entitled “Teaching Soren Kierkegaard’s Fear and Trembling.” The author of the article is Jonathan Malesic (2014), an associate professor of theology at King’s College in Pennsylvania. The article discusses Professor Malesic’s attempt to teach his students about Kierkegaard’s very influential work, Fear and Trembling (Malesic, 2012).…
This paper presents The Aeneid Vergil, a book translated by Sarah Ruden. It will mainly focus on the books 4 and 6, in which the principal character Aeneas experiences important events: love and its arrival to the promise land. This analysis will consist in identifying how fate has impacted Aeneas’s life since the beginning of his journey. Also, it will discuss on whether fate goes along with one’s happiness or contradicts it.…
The practice of leaving offerings for the Gods was common in Greek religion, offerings could be left at the temple of a certain God in order to gain their favor, or in gratitude for successes which could be attributed to that God. The size and grandeur of the offerings differed drastically among social classes, the poorer classes often offering only small terracotta figures of animals in place of an actual blood sacrifice. The physical objects left behind can be highly revealing of the society at the time, and when supplemented with literary sources, they become even more informative.…
Ptolemaic empire which started with Ptolemy I Soter's accession after the death of Alexander the Great in 323 BC, which was the second empire to spilt by the hellenistic kingdom. The Ptolemaic empire ended with the death of Cleopatra VII and the Roman conquest in 30 BC. The Ptolemies of Egypt was found by Ptolemy who declared himself a Pharaoh of Egypt. Ptolemy created a Hellenistic dynasty that ruled from southern Syria to Cyrene to south of Nubia, which became a powerful Hellenistic dynasty. The capital of city is named after Alexander the Great called “Alexandria”.…
Sophocles’s use of both plot and character within his classic tragedy “Oedipus the King” portray the religious and ethical views of the Classical period of Ancient Greece to such an extent that Knox goes so far as to say that “the audience which watched Oedipus in the theatre of Dionysus was watching itself.” Marlowe uses similar tools of character construction and plot in “Dr Faustus” to reflect the beliefs and moral attitudes held in Elizabethan England. The playwrights both use the conceptions of their protagonists to present contemporary beliefs; for example, the initial portrayal of the characters of Oedipus and Dr Faustus demonstrate ideological characteristics of a man within their respective contexts. On the other hand, with the…
Meno begins his quest to have Socrates explain virtue by nature by stating that having beautiful things is to have virtue. “So I say that virtue is to desire beautiful things and have the power to acquire them” (77b). To help him to understand that this statement is not complete, Socrates inquires about specific characteristics that might comprise having something beautiful. These characteristics include wealth, a position of honor, justice, and the pursuit of happiness. Only in perfect combination to all of these specific characteristics assert “virtue as a whole” (77a)…
Scientists continue to search for and conserve little-known plants those whose medicinal properties have become crucial in the fight against diseases. Moreover, lessons from folk medicine, indigenous knowledge and Chinese medicine on crude extracts points to possible finding of novel promising and strong pharmaceutically bioactive constituents. Arum palaestinum, commonly known as Black Calla Lily, is one of the important medicinal plants belonging to family Araceae which has not been well studied. Little is known about its pharmaceutically bioactive substances and effective conservation through the use of biotechnology so; it is selected and reviewed for its phytochemical analysis and its biological activities. Besides, the tissue…
