The abiotic factors that affect plant growth and development include topography, soil, and climatic factors. They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetic factor is expressed in the plant. Topography Topography is a nonliving factor that refers to the “lay of the land.” It includes the physical features of the earth such as the land elevation, slope, terrain (flat, rolling, hilly, etc.), mountain…

It was found that the cores were too weak due to an engineering flaw when curing the concrete. Engineers in an effort to save time on the project moved to accelerate the curing process. In order to accelerate the process nitrogen gas was added to the concrete mixture. The nitrogen gas expedited the curing process however there was a cost the came with the accelerated curing. The cores produced using the accelerated process were found to be too weak to withstand certain pressure surges caused by…

And I find chopsticks frankly distressing. Am I alone in thinking it odd that a people ingenious enough to invent paper, gunpowder, kites and any number of other useful objects, and who have a noble history extending back 3,000 years haven't yet worked out that a pair of knitting needles is no way to capture food?" (Gunpowder quotes), this quote talks about how the Chinese made many great inventions like gunpowder. Gunpowder is very important because it created a weapon of mass destruction that…

begin to be absorbed into the blood and tissues keeping in mind that with depth, the chest is being compressed simultaneously. Consequences can be the immediate release of Pn2 and Po2 back into the body causing nitrogen narcosis (Encyclopedia, 2014). 2) Decompression Sickness is when the Nitrogen that was stored in the blood and tissues while descending in the water, forms bubbles within the tissues upon the ascending or pressure decrease (Encyclopedia, 2014). 3) Signs and symptoms of…

1. Even though, the eruption of Mount St. Helens volcano was one of the most severe eruptions yet, some plants survived the upheaval. Ecologists were surprised to find the emergence of plants in the mass of ash covered terrain. As the ecologist Dale quoted, “It gave the impression of total lifelessness.” However, roots being guarded in moist soil, resilient plants, and snow sheltering trees were the three main reasons vegetation survived. 2. The plants, and trees that endured the eruption are…

Back on the date of June 18, 1773 Joseph Priestley was in his science lab exploring and studying about the elements. Priestley had done a lot of experiments to find more about the element now known as oxygen. The first experiment dealt with using the previous methods Carl W. Scheele used. Carl W. Scheele was a chemist from sweden, but in his discovery of oxygen he had other people helping him throughout the process. Joseph had thought in his mind, “ If I can do this scientific inquiry on my own,…

What kind of soil structure that supports the growth of garden landscaping? The structure of the soil fertile and flat is coveted for each kind of garden landscaping. But for those of you that have outdoor areas like slopes, how to make garden landscaping? What is the area of hillside garden landscaping can be made? Of course it can, although the contours of the land are like that, you can still create a garden or often called the hillside landscaping. But when you happen to have to make the…

The invention of gunpowder was drastic and life altering discovery. Gunpowder was discovered in Ancient China in the 9th Century during the Han dynasty, by an alchemist named Wei Boyang (A&E). Boyang was one of the many alchemists hired by the government to create an exlir that would satisfy the emperor’s search for immortality. Through his research he accidentally came across gunpowder. The alchemists “experimented with the Sulphur, common charcoal, and saltpeter heating the substances in order…

Bud bank dynamics (Benson, Hartnett et al. 2004) study suggest that the densities and dynamics of tallgrass prairie plant populations, as well as their response to disturbance (e.g., fire and grazing) and climatic variability, may be mediated principally through effects on the demography of belowground bud populations. Patterns of seed reproduction and seed bank populations have little influence on short-term aboveground population dynamics of tallgrass prairie perennials. Our results indicate…

Fertilizer is a key variable in growing nice and healthy plants for your garden. You don't want to give to little or too much fertilizer to your plants, because then your plants won't grow so good. To prove this I took five plants and used Miracle Gro 3x fertilizer and used eighty to two hundred and twenty five milliliters of fertilizer. The steps i took for this experiment was pretty simple i filled the containers with soil and tomato seeds. Then I used measuring cups for the fertilizer…
