Venus flytrap is a carnivorous plant native in bogs and swamp lands in North and South Carolina. It was discovered in the 1700s and named after the Greek goddess Dione which gave it the scientific name Dionaea. The species name muscipula came from the Latin word “Mus” (mouse) and “Cipula” (trap). Venus flytrap is one of the only two known species of plants that use fast-closing, double-spaced trap mechanism to capture insects. The leaf of a Venus flytrap have two primary regions: a leaf-base that is capable of carrying out photosynthesis and grows out the ground and trapping mechanism; there was also a leaf-blade at the end of the leaf that is composed of two lobes hinged together by midrib. Venus flytrap each have between two to five trigger hairs on each lobe with three hairs on each lobe; the edge of the trap is lined with finger-liked cilia laced together when the trap shuts.

To attract the insect, a mature Venus flytrap will grow a very long stalk so that the insect won’t get accidentally eaten. “At the top of the stalk, white flowers that secrete sweet-smelling chemicals, pollen and seeds that are 1mm long”. Venus flytraps has to be serval years old before it can get enough energy to make flowers and seeds. (http://www.ehow.com/how-does_4911676_venus-flytrap-reproduce.html Sexual reproduction in the Venus flytrap is no different than the other plants. Venus flytraps can be self-pollinated, meaning that you can fertilize the pistil with pollen from its own anthers. A few days after fertilization, the flowers will wither and die. The seed matures in 4-6 weeks after pollination occurred. “As the seed has matured, the tiny ovary turns jet black; about 1.5mm in length”. If the pollination attempt was unsuccessful, there will only be dead plant material.
One key distinction is the sex combs on the male’s foreleg, which is characteristic that is lacking in the females. Another way to distinguish the sex of the flies is to carefully examine the tip of the abdomen in each. The females tend to have a lighter colored abdomen that is more pointy and long. On the other hand, males tend to have darker pigmented abdomen that is round and short. In general, females tend to have a larger body than males. Sex determination can easily be accomplished even under a low power magnification, which adds to the ease of using fruit flies to study genetic

1.) Discuss the meaning of the Paleolithic Venuses. Identify Rice's position and explain it. Discuss four other interpretations of these figurines mentioned in class or in the reading. Do any or all of these interpretations support the views of the 19th century evolutionist Johann Jakob Bachofen?
The Drosophila live a distinct four-staged life cycle that requires approximately two weeks to reach complete maturity2. The stages are known as egg, larval, pupa, and adult. The egg is a small oval shape, and can barely be seen by the unaided eye, they are hatched the day after being laid. In order for the larva to molt and grow in size it consists of three stages: first instar, second instar, and third instar3; during this process the larvae is preparing itself for metamorphosis by shedding body parts and consuming excessive nutrients. Through metamorphosis the immature fruit fly attaches itself to an object and its outer shell hardens, it then begins the transformation process into an adult. Once the process is completed, the adult is then able to begin the sexual reproduction process within forty-eight hours....
The life cycle starts as larva or caterpillar. First, the monarch lays the eggs on the milkweed plants. Next, the egg hatch into a caterpillar. The caterpillar then eats the milkweed plants until they are large enough to pupate (Emmel, 1999). Then, the caterpillar attaches a pad of silk to a stem of a milkweed plant so it can hang while it transform into a butterfly. Next, the caterpillar sheds it larval skin to reveal the chrysalis inside (Emmel, 1999). After it shed its skin, the pupa hardens and the chrysalis earns it name by glowing in the sun. As the pupa stage comes to an end, the butterfly can be seen through its pupa shell. The monarch emerges by splitting the pupa along the length of it proboscis (Emmel, 1999). First the legs emerge. Then the fluid fill body pumps its fluid into the veins of the wings while the body shrinks to normal size. Finally, the butterfly hangs from the pupa about two hours while the wings dry (Emmel, 1999).

Firstly, Venus’s atmosphere is heavily laden with carbon dioxide (CO2), which makes up 96 percent of its atmosphere, 3.5 percent is made of nitrogen, and the remaining 0.5 percent is a combination of water vapor, sulfuric acid (which produce Venus’s thick, stable clouds), hydrochloric acid, and hydrofluoric acid. Venus’s upper atmosphere is cool, which the lower atmosphere is extremely hot and causes the surface temperature to rise to 470C (880F). Venus’ present atmosphere is very dry, but shows signs that it may have once contained water. An abundance of deuterium—the heavy isotope of hydrogen—developed, but was broken down into hydrogen and oxygen atoms by ultraviolet radiation that could not be absorbed by Venus’s lack of an ozone layer (Seeds).
The venus flytrap is a unique plant that is known to be a carnivore. Many people are fascinated by this plant’s peculiar diet. While many people are surprised by this plant’s food, only few know how this strange plant attracts, kills, and digests their prey.
There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).
The Venus of Willendorf and the Venus de Milo are two ancient day venus sculptures representing two different views on beauty. The Venus of Willendorf is a small 4.5 inch limestone figure of a Goddess which is believed to be used as a fertility symbol, while the Venus de Milo is a tall ancient Greek statue of a Goddess which is said to represent love and beauty. The Venus of Willendorf’s body structure is very different than that of Venus de Milo. The venus of Willendorf appears to be a short lady with a large emphasis on her reproductive organs, breasts and stomach area whereas the Venus de Milo appears to be very tall with smaller breasts, and a really athletic build. She appears to have abs and looks as if she has not had children before, while the Venus of Willendorf looks like she has had children due to her huge breasts and stretched out belly button.

Abstract: Even before Darwin’s time, scientists were intrigued with the Venus Flytrap (Dionaea muscipula). Since then, much has been learned about this rare carnivorous plant that feeds on living matter rather than through the process of photosynthesis such as other plants. Researchers continue to study specific aspects of the plant such as its closing mechanism and evolutionary tree, as well as newer issues such as the value to pharmaceuticals and healthcare and its adaptation to other geographical areas such as the bottom of the sea.
The Birth of Venus by Sandro Botticelli depicts a moment from Venus birth when she stepping, almost floating, off the seashell that was blown ashore by Zephyors along with Chloris. Horae awaits Venus arrival to shore with a large red cloak to cover her naked body .Venus is the Roman goddess of love, sex, beauty, fertility, and prostitution. Venus is the Roman Aphrodite. Born of seafoam from a singled drop of blood in to the sea from the castration of her farther Uranus by his son Saturn.
Well in the spring all the males and young winged queens leave their nest and fly high in the air and mate. The few ant queens that survive this “marriage flight” cast off their wings and instinctively begin to look for a spot to start a new ant colony. After making a nest, the young queen ant seals off the entrance and begins to lay eggs. Some of the first batch are eaten by the queen for nourishment. When the surviving eggs hatch, they become like larvae. After a few weeks each larva spins a cocoon around itself and pupates.
