Seed Dispersal
The experiment will be investigating how seeds are dispersed by nature. Seed dispersal is the transportation of seeds from their parent plants. Plants are not mobile, therefore seed dispersal is necessary to transport their seeds. Seed dispersal is important because if the seeds are not scattered, then the seeds will grow near parent plants, thus resulting in competition for light, water, space, and nutrients. Seed dispersal also helps reduce predation for the seed. Predators tend to direct towards areas of high concentration. Seeds can be dispersed in four ways. First, seeds can be dispersed by wind. Seeds with feathery bristles can be carried long distances by the wind, while some seeds are carried freely. Sometimes wind dispersal is not as effective as other dispersal methods, so plants need to produce a great quantity of seeds. Second, seeds can be dispersed by water. Plants that grow near a body of water often rely on water for transportation of their seeds. Some seeds produced by tropical plants can be carried thousands of miles. Plants like the willow produce seeds underwater, while plants like the water mint produce seeds on land. Third, seeds can be dispersed by animals. Animals will eat the fruits, and deposit the seeds in their droppings miles away. Another way animals disperse

For the experiment, the seed will be taped to the structure and dropped from the second floor. The seed should be dropped straight down and the airtime should be measured from the drop to the point of first touching the ground. The surrounding environment should not influence the experiment in any way. The data recorded is the time in the air (airtime), and the distance from the point of first touching the ground. The control group in the experiment is the seed dropped without the structure which aids in the dispersal
That is why a group of students in Winnepeg decided they were going to grow the seeds. The seeds were from a type of squash, which was extinct. The students were able to bring this squash back to life by growing the seeds. The students are eager to let the rest of the world know about the squash.
Did you know that our food supply depends on seed banks? This essay will tell you all about them! Seed banks are important to maintain both national and global seed banks, as well as what may threaten the survival of the seeds kept there because they keep seeds from going extinct, they supply farmers with seeds whenever they need them, and they protect the seeds. First off, seed banks are important because they keep seeds from going extinct. We need most seeds to survive.
A seed is planted and taken care of
The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
Science 1. Free ears in dogs are controlled by dominant allele (F), and attached ears are controlled by the recessive allele (f). In addition, Short dogs is due to a dominant allele(S), and long hair is due to a recessive allele (s). Which of the following is the genotype of the dogs with free ears and short hair? a. ffss b. FfSs c. ffSs d. Ffss 2.
Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O
Wheat, oats, and barely are all new foods brought to the Americas which also had weeds in between the seeds which displaced native flora and fauna.
Predators then eat the animals who eat the plants and each
8) Explain how each experiment type (question 7) differs from the
All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.
If you are passionate about something you should believe in it, and also take the risk and aim for it. In “Field of Dreams” Ray Kinsella takes an enormous risk by building a baseball field when he hears a voice. In “The Thrill of the Grass” the narrator strongly dislikes the use of artificial turf so he sneaks into a stadium changing the field one square piece at a time. Both characters face tremendous chances, but with the people they love they follow their hearts and take these great risks.
In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Thus the measurements will repeat for each experiment, where the paper cup’s height from the ground varies in each
This experiment has to be carried out carefully
The experiment shall use several concentrations of sucrose solution and a substance known as Methylene blue. A piece of potato/ carrot shall be placed in a boiling tube and the solution shall be poured into it. This tube shall have Methylene blue added into it. After incubation some of this solution shall be taken out with a pipette and inserted into a separate boiling tube containing the same sucrose solution however this solution shall be known as the pre-incubated solution. The drop shall be watched so as to see if the density of the water and concentration of sucrose has increased or not, displaying the water
