Seed Dispersal by Wind
Sujit Vankineni
Introduction: Seeds can move in many different in which some are by water, animals, and wind. The most easiest to conduct would be the wind and that is why we are using wind as the type of dispersal for the seed. In animals, seeds can be dispersed by barbs or other structures that can get tangled in the animal fur and the animals take the seed some other place until the seed gets untangled. Another way the animals can disperse seeds is when the seeds is digested and dropped through the anal after digesting the seed. Some animals bury seeds in the ground. Examples of these animals that do these type of seed dispersing include squirrels, birds, snails, and catfish. Water can disperse seeds by

In trials 2,3,4,11,12,13,14, and 15 all supported the hypothesis. The reasoning for the carrier being able to carry the black eyed pea seed at least 85 centimeters was because of the gliders lightweight and the wings of the glider or the aerodynamic of the glider. The formation of the glider easily allowed the air to circle around inside making the glider go farther as the glider went down. Also the weight was never too much on one side of the glider instead the weight was always balanced making the glider more easier to fly down. Some inferences about the Seed Dispersal Lab by Wind experiment that can be made is that in nature the seeds sometimes bounce off wherever they land to get farther or sometime the seed lands next to the offsprings parents if the wind isn’t strong enough. Another inference that could be made is that out of all the other wind dispersal typed a glider is not the best way all the time, this is because if there is not enough wind the glider cannot go anywhere as in a helicopter or spinner they can travel more farther than a glider because they have wings that can take the seed longer distances. Some sources or errors include, that the teams glider sometimes kept on hitting the wall of where we were standing which lead to interfering with the groups data as the data would not be constant because the glider did not always hit the wall. Another source of error is that the glider kept on hitting people as the glider came down and that source of error interfered with the team's data as well. A crucial source of error is that the glider got a small cut around the 10th trial which made the glider lose balance as the air went in more on one side than the other side. Some questions that could be asked from this experiment is “What happens

Does a father love his son? Josh wondered if his father loved him many days during his younger years, and love takes on a whole new meaning in Irene Hunt’s book No Promises in the Wind. The book starts out in Chicago in 1932 during the Great Depression period, times are tough as Josh’s father is without work and putting a simple meal on the table is a blessing. Josh also finds himself resenting his brother Joey because when he was born was when all happiness in the family ended, due to Joey’s many medical problems. This is one of the reasons that prompts Josh and his friend Howie to run away and find a better life, while Joey
We then allowed the larvae to hatch, and counted and recorded the total number of flies, the phenotype, and the sex. After taking down all this information this would allow us to perform a F1 cross, we made sure to examine the flies carefully since we needed virgin flies. We prepared a new vial with the a 1:1 ratio of medium and water. After recording the data of the F1 generation, and picking out the virgin flies for the crossing, and we killed of the rest of the flies using the oil method. After some time passed the F1 generation had larva in the vial. Once we noticed the larva we had to put the flies to sleep and collect the data. We then had to prepare another two new vials and medium and water. Carefully observing the flies and picking out three males and three female virgin flies to place into the new vial. Than killing of the other flies. After about a week we had the F2 generation. This was the most important generation, it was what we were looking for to allow us to observe and compare our experiment to Mendel’s experiment. We were looking for a 9:3:3:1 ratio with our flies. Using a basic Punnett square table and the crossing that we had accomplished our results should have looked like the following Punnett square.
The purpose of the first experiment, Ebony vs. Vestigle was to see how many of the offspring had normal bodies and normal wings, normal bodies and vestigle wings, ebony bodies and normal wings, and ebony body and vestigle wings. The purpose of the second experiment White vs. Wild was to see how many of the offspring were red eyed male, white eyed male, red eyed female, and white e...

...der was designed to hold a pilot on his stomach in the center and would control the movement of the craft through a process that would become known as "wing warping". (Cite) On a windy day, the brothers tested their glider. Wilbur was the pilot while Orville and a man named Bill Tate held ropes that would steady the glider like a kite. The craft was successful and lifted fifteen feet off the ground. (Cite) After the successful flight though, the brothers ran into a slight set back. While adjusting the glider, a wind lifted the craft off the ground and the glider was smashed onto the ground a few yards away. This crash was not the last setback the wright brothers experienced. After many successful flights later on, the brothers began to look for a way for the glider to be self-powered, and not have to rely on the wind. Their glider needed a propeller and an engine.
When it comes to genetic diversity and migration, migration is known as the movement of genetic diversity within a species. Migration of genes not only happens in animals but also in plants through pollen dispersal, vegetative propagules like rhizomes and suckers among others. Migration or in other term gene flow, is said to take place both with the proceeding front of a population when it is colonizing new areas. This happens when genes of two or more populations mix through pollen and seed dispersal. In this case, migration rate is mainly related to the frequency of reproduction and the distance over which seeds and pollen usually disperse.
Seedfolks is a book about family. One day, a little Vietnamese girl named Kim plants some lima beans in a vacant lot in Cleveland to honor her father who was a farmer. A neighbor notices and decides to plant her own plants. Soon, more neighbors notice and do the same. Soon, the vacant lot turns into a community garden. The people of Cleveland have to avoid their differences and come together as a family to make it successful. The book Seedfolks implies that family is the true source of love because almost everybody in the book does something to express their love through the garden. The garden becomes somewhat like a family, and brings the community together.
Imagine a world where animals walked, talked, and lived like humans; where rats went boating, toads drove cars, and moles went on picnics. This is the reality in The Wind in the Willows by Kenneth Grahame. The river, the forest, even the prison are all locations you'll get to visit in this tale revolving around the adventures of Rat, Mole, Toad, and Badger. Grahame's rich language and enjoyable characters are captivating, making you want to find out what happens next to these four friends.
E.K. Hornbeck through his language in “Inherit the Wind” (1955) tries to show the town of Hillsboro the way that their thoughts are harmful and wrong. Hornbeck backs that up by using a sarcastic tone to show them how ridiculous they are being, by using metaphors and similies to give the citizens context from the outside world that they might not always consider due to their closed mindedness, and by using syntax to prove that he is better than them and making himself and his views credible. His purpose is to get the town to change their viewpoint so they can see that they need to move forward with the time. He establishes a superior relationship with his audience of small town people with narrow viewpoints who need to learn to be more accepting.
A theme in W.P. Kinsella’s “The Thrill of the Grass” is change, for better or for worse, affords the opportunity for us to acknowledge our emotions and love of memories and encourages us to stand up for what we truly believe in. Change, sentiment, reminiscence and defiance are portrayed through the protagonist and the plot in this admiringly, well written short story.
UXL Encyclopedia of Science (2002), stated that seeds are a part of plant. It can be the cause for a new plant. When plants grow they will produce another set of seeds until the plants spread through the given space to them.
The trials and tribulations of flight have had their ups and downs over the course of history. From the many who failed to the few that conquered; the thought of flight has always astonished us all. The Wright brothers were the first to sustain flight and therefore are credited with the invention of the airplane. John Allen who wrote Aerodynamics: The Science of Air in Motion says, “The Wright Brothers were the supreme example of their time of men gifted with practical skill, theoretical knowledge and insight” (6). As we all know, the airplane has had thousands of designs since then, but for the most part the physics of flight has remained the same. As you can see, the failures that occurred while trying to fly only prove that flight is truly remarkable.
The seed could be anything during one’s life. The seed could be one’s goodness or forgiveness. The seed could be one’s perseverance and/or faith. As long as one plants these seeds with honesty, courage and trust throughout one’s life and career, they will reap the greatness of friends, miracles and victory.
