How Venus Fly Traps Catch Their Prey 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. To begin with, the upper and the lower leaf on the venus flytrap produces a sweet nectar, that is spread on the open traps of this plant, for attracting insects. Then, the insects smell the nectar and land on the plant’s leaves causing them to trigger the venus flytrap’s trap. At first the plant closes it’s trap lightly so that small insects, that the plant does not want to eat can escape, but once larger insects start to struggle, the leaves will clam together tightly over the plant’s meal. Substances produced by insects can cause, the trap’s leaves to be more tight when closed, because of that it only takes a few minutes for the traps make airtight seals.

Each side of the trap has about three or four hairs that can sense insects, but even though the hair can sense them, an insect still must trip the same hair two times or trip to two hairs in 20 seconds. If not, the trap will not respond. The venus flytrap has this feature so it doesn’t snap shut on false alarms such as raindrops, or pieces of debris. When a hair is first triggered, it creates an electrical signal that travels on the trap, which much like an electrical signal that would travel through an animal cell. Than the energy is stored. When the insect trips, that will generate another electric signal. With the energy from both signals, it will require the trap to

The objective of this experiment is to determine what genes are responsible for the white-eye color in two strains of Drosophila melanogaster, known as the common fruit fly. Drosophila is used as the experimental organism for many reasons which include its small size, easy maintenance, short 10 day generation time, and a fully sequenced genome. The characteristics of the wild type, which is the most common phenotype found in nature, include brick red eyes, long wings, gray/tan body, and smooth bristles. Of course, there are mutations that occur that cause specific traits to deviate from the wild-type phenotype. These traits include wing length, bristle shape, body color, and eye color.
The purpose of this experiment is to conduct genetics studies using drosophila fly as the test organism. Scientists can study the basic biology that is shared by all organisms using a model organism, such as drosophila fly1. Drosophila fly, or more commonly known as fruit fly, has several qualities that makes it well suited for experimental genetics cross. First, fruit flies are low maintenance organisms. They are small in size (few millimeters long), so they occupy a small space and a lot of them can fit in one vial at the same time. They only require a media to feed on. In this lab, instant media was used, which is efficient as it only requires the addition of water to be used. This media contains ingredients that the fruit fly can feed one,

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).

A hundreds or sometimes millions of pollen grains per flower are collected by honeybees and packed into pollen pellets on their hind legs with the help of special combs and hairs (Krell 1996). While forager bees forages on the flower for nectar, the pollen particles get dusted on them. Pollen is brushed of the worker’s body by their front and middle legs and transferred to a special structure in the hind legs called the cubicula or pollen basket. Forager bees unload their pollen by kicking the pollen pellets off their legs into the cell. These pollens are refe...
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).
Venus’s standing inside a large pearl colored seashell with golden edges, represents female genitalia giving a symbolic birthing scene, and has been blown ashore by Zephyors and Chloris who’s floating above the sea on the right of Venus. Zephyors is the god of the west wind ,his face shows strain from the power of his breath his cheeks inflated with air ,lips puckered , forehead wrinkled with by the force he’s expelling the wind. Zephyors skin is tan with long brown hair the same as the color of his angelic wings , his body is in a bracing pose with his arms pushed back with his hand opened his chest exposed and forced forward, his blue cloak tied around his neck is blown back from the winds wrapping around his right arm and pelvis. Zephyors left hand is wrapped around Chloris. Chloris is a nymph associated with spring and blossoming flowers, her arms are wrapped around Zephyors with her fingers intertwine on his right side her right leg is hooked on his upper left pelvis down to his knee. Chloris upper body is facing Zephyors with her head nearly touching his looking towards Venus, her mouth is slightly open face relaxed her eyes focused on Venus almost in awe of her beauty .Chloris cloak tied on her left shoulder rich dark green color with gold highlights draped over her body with her left breast exposed. Her skin
In his studies, Lindeur found that about a hundred scout bees leave the swarm to find a satisfactory nest site. He also discovered that when a scout has found a possible site, it will come back to the swarm and communicate the location of the site to other scouts. The honey bee does this by perf...

On day’s one-two, they clean cells. After the worker bee emerges and grooms herself, she cleans her own cell and others so they can store new eggs. Once the cells are tidied up, new eggs can be placed in the cells so more honeybees can be born.
One of the first reason why insects are so successful because they possess a tough exoskeleton that is covered with a waxy water repellant layer. The exoskeleton of insects also has helped them survive. An insect's external skeleton, or exoskeleton, is made of semi-rigid plates and tubes. In insects, these plates are made of a plastic like material called chitin along with a tough protein. A waterproof wax covers the plates and prevents the insect's internal tissues from drying out. Insect exoskeletons are highly effective as a body framework, but they have two drawbacks: they cannot grow once they have formed, and like a suit of armor, they become too heavy to move when they reach a certain size. Insects overcome the first problem by periodically molting their exoskeleton and growing a larger one in its place. Insects have not evolved ways to solve the problem of increasing weight, and this is one of the reasons why insects are relatively small. But compared to animals the Exoskeletons d...
Venus was formed 4.6 billion years ago along with the Sun and the solar system. Large amounts of dust and gases accumulated over many years to form the planet. Venus is thought to be the result of a large collision. This is due to the fact that Venus rotates differently than the other planets in our solar system. Venus is commonly referred to as Earth's "sister planet" because of their similarity in size as well as a similar gravitational force. Although Venus and Earth share some similarities, it has shown to be very different from Earth in many other aspects. It has the most dense atmosphere out of the four terrestrial planets. Venus consists of more than 96% carbon dioxide. The surface shows evidence of extreme volcanism, and the sulfur in the atmosphere may mean that there have been some recent eruptions. Venus is covered by a thick atmosphere, creating a blazing environment with temperatures reaching high enough to melt lead. Much of Venus's surface appears to have been shaped by volcanic activity. Venus is home to about 167 large volcanoes. Some stretching over 100 km long. Ven...
