All animals with limbs have a common design. If a batwing were to be formed from a person’s hand, make the fingers extremely long; a horse elongates the middle fingers and reduce and lose the outer ones; frogs elongate the bones of the leg and fuse several of them together. All in all, despite radical changes in what limbs do and what they look like, this underlying blueprint is always present.
Almost every Native American tribe has significant stories about the eagle. One story from the Walla Walla tribe concerns the two identical wing feathers found close to the breast on each wing. The two feathers are called “THE TWINS”. These feathers are aerodynamic and able to be twisted by the bird to give a smooth level effortless flight, when riding thermal currents. Indians in their superb wisdom, learned from their observation of the eagle. They had
I chose the article called “Swarms of CICADA Drones Could Aid Hurricane Research”. I chose this article because it sounded intriguing. The article explained how drones could help during natural disasters and such. These drones can go through a town after say a hurricane and it can help tell us the damage done, if there are any people in danger and it could help the volunteers locate the people in danger. I think this is incredible. I think that this is a great idea and could help save lives. A drone like this can not do anything but help, it is not gonna put people in danger or invade people's privacy, it could only help them. It can also tell the damage of the natural disaster which can be helpful when you do not know what to expect and then
There are a few key threats to the Acadian Flycatcher population. Throughout its range the species is threatened by habitat degradation and fragmentation. The main factors for loss of habitat are the conversion of natural forests to pine plantations, residential development, strip mining, and road construction. (NatureServe 2015) These impacts are found both in their northern breeding territories and in their tropical wintering
To start, a fly anesthetic was used named “FlyNap” to anesthetize the drosophila melanogaster. A fur wire was then dipped into the FlyNap and then placed into the vial with the vial on its side being careful not to uncork the foam plug. After about a minute the drosophila melanogaster become unconscious. The unconscious drosophila melanogaster are then swept onto a plate with a small paintbrush. Once they are on a plate they are then to be scored with a compound microscope. For the experiment five females and five males were required to be placed in vial with at the bottom of this vial were some parts dry fly food, mixed water, and granules of yeast. While keeping the vial sideways sliding a small portion of plastic netting and then
A bird flies wildly about, twisting and diving. It is panicked, trying to escape the boy on the ground below, who hurls small, painful missiles at it from a slingshot. The creature of the air is a splendid sight; the wings are as if covered in jade paint and the tips dipped in a ferocious scarlet. The breast is a majestic solid blue, its throat a sulphur yellow. And the head and the tail both are a livid, dark purple: beautiful.
Diversity among species begins at the embryo stage of development. Scientists have found that many of the reasons that species vary, why some fly’s had wing spots and why others did not is because DNA has the genius mechanism of switches. The switches have the ability to turn genes on or off. Finding the exact reason for why some genes are turned on or off is still being studied. Scientists are beginning to see that much of the reason there is such great diversity among species, ones that are similar and those that are completely different, lies in what happens during the growth of the embryo. By studying the Galapagos finch eggs Cliff Tabin was able to view the growth of the finch beaks and see that the exact same gene is responsible for the beak size in the smaller beaked finches and the larger beaked finches. The difference came solely from the degree that the switch was turned on, whether barely on or all the way on, when it is turned off and the precise moment when was the exact indicator for the beak size the finch would receive. It is known however that the body plan switches are the driving force behind what genes get turned on and what genes get turned off. It is amazing that we can find genes that target specific body parts and find genes that are responsible for certain duties, or even why certain genes cause certain disabilities. It is
I was doing yard work for my grandparents and i found this. I had to identify what it was and i figured out that it was a cicada bug shell.
With a gestation period of seventeen years, the Magicicada has been believed by naturalists to be a symbol of love and music and is one of the few species with such a unique pattern of emergence. Upon awakening from their seventeen-year slumber, the great cicadas emerge in swarms of millions all along the northeastern United States to sing, mate, and die. It is still unclear why this mythical emergence only occurs on a prime-number scale. Scientists hypothesize Big Idea Three of the AP Biology Curriculum Framework highlights how genetic information is a repository of instructions necessary for the survival, growth, and reproduction of the organism. Although the reasoning behind why the cicada only emerges once every seventeen years is unclear, the insect has been genetically programmed to this routine for the entirety of its existence, meaning that whatever the reason, this emergence must be essential for the bug’s survival, growth, and
The Order Trichoptera offers around 1400 species of Caddisflies in North America (citation).The caddisfly is found in almost every freshwater habitat. Temperature, water speed, and amount of sun exposure are all specifically selected by certain species (citation). They thrive mostly in cool rushing waters, but are still known to be found in lakes, ponds, springs, and temporary pools. Most often they are found in riffle areas within a cool flowing stream. In the beginning stages of the caddisfly life cycle, they are submerged underwater in a larval form. As a larvae they provide shelter to themselves by constructing a case out of natural materials they find in their environment, and silk which they can readily produce. They choose to either fix it to a rock or permanent object, or they can swim around with it attached
All across the United States, from North Carolina to New Jersey and through Ohio, legions, large groups, of cicadas are waking up and beginning to reproduce. Located in the woods and forests, cicadas are emerging from the ground and looking for partners. However, in a month, all these cicadas will be dead and the next generation will be sleeping underground.
The Venus flytrap preys on insects with its unique shaped terminal portions on its leaves called the leaf-blade. Each trap has between two to five “trigger hairs” on each lobe. The edge of the trap is lined with finger-like cilia that lace together when the trap closes. The trapping mechanism and digestion process is divided into four phases: the initial snap, the tightening phase, the sealing phases, and the reopening phase.
Birds have beautiful feathers and lovely songs that bring joy and wonder to us humans. And flight is the feature that probably captures the human imagination more than anything else. For millennia, people have watched birds in the sky and wished we could fly, too.
Among the millions of unique organisms that inhabit the Earth, one of the most breathtaking of all these creatures is the Ignis avem, more commonly known as the fire bird. This fascinating creature’s unique genetic makeup allows for its fascinating features and traits which separate it from the rest of the natural world as one of the most complex creatures alive. The Ignis avem is a multicellular organism that is classified as an animal due to its reptilian and bird-like attributes.These traits originate from its DNA, 40% of which resembles that of an alligator, 20% of a hummingbird, 20% of a falcon, and a final 20% originating from bald eagles. Each of these genetic relatives of the Ignis avem contribute a feature which allows it to be the deadly predator that it is. For example, the hummingbird’s unique wings are exhibited by the fire birds ability to flap its wings at intense speeds and change direction in the matter of seconds, allowing it to ambush it's pray effectively. In addition, the alligators dominance in the fire bird's genetic makeup is shown by its long, dagger filled snout which allows the fire bird to catch jumping fish and quick-moving birds with a single snap of its mouth. Lastly, the falcon and bald eagle facets of the fire bird are shown through its keen eyesight from great heights, as well as its deadly talons. Essentially, the firebird's unique ancestors and genetic relatives lend themselves tremendously to its unique DNA and traits which make it the
