crop rotation or resting the soil. Production levels on dryland outfield plots cropped in maize decrease immensely over time, because of the decline in soil nutrients critical for plant growth. Maya kings monopolized artificial reservoirs and other water sources during annual drought as a way to adapt during the…

The Cremation Process, Explained Cremation refers to the combustion, oxidation and vaporization of a corpse to basic chemical compounds, including gases, mineral fragments and ashes. Following cremation, the family of the decedent receives a container or urn that holds their loved one’s ashes. Many times, for financial reasons, an individual will forego a funeral with a burial, opting for cremation: The National Funeral Directors Association (NFDA) states that since 2005, cremation rates have…

Within the human body, the natural process of moving soluble molecules across a membrane is referred to as passive transport. For this type of transport chemical energy is not necessary. Two of the main types of passive transport that the human body utilizes are osmosis and diffusion. Diffusion is the movement of a hydrophobic substance across a semi-permeable membrane without the use of cell energy from a gradient area of higher concentration to an area (either inside or outside of the cell)…

Pablo By: Rok Outside of the water there were kids playing on the beach while their maid drones supervised them. Oops! I forgot to introduce myself! I’m Pablo, Pablo Ferisa. You may not be able to tell this but I am a sea monster. But I’m not scary! I’m really nice! I just want to be the humans’ friends, but their maid drones just protect their children. I was swimming near the beach in the Florida Keys. I slowly surfaced. I swam by a piece of trash. These maid drones discard their…

great, gather the materials needed; such as dog friendly soap, a cup/bucket to wet the dog’s fur, have a towel or two ready for when the bath is over, one to place on the floor so water does not get all over the place and one to dry off the dog. Grab a plug or a small wash cloth to stop up the drain, being running the bath water, it should not be scalding hot but also not shivering cold. After all these steps are completed go fetch the sticky fur ball and remove his/her collar. If the dog is…

On May of 1980, Jimmy Carter who was the President of the United States at that time issued an emergency disaster declaration, based on the mental distress the residents of the Love Canal had experienced, instead of the chemical and physical hazards the community was exposed to. The state of New York subsidized the project and sold the houses at a lower rate with the intention to end the disaster that occurred in the area, as both New York and the city of Niagara Falls wanted to put to rest and…

attracted to the white or colored “nurdles”, possibly thinking it is fish eggs or food of some kind. The plastics are ingested and the toxicity is transferred to the fish tissue and magnifies up the food chain. Any oceanic animal that filters the ocean water through their system is affected by the plastics that have been broken down by UV rays into smaller and smaller pieces. Many of the harmful effects are impacting the endocrine systems of the ocean animals. Third world countries have no clue…

through a thermal decomposition reaction that causes it to dissociate into potassium chloride and excess oxygen. The gummy bear is mostly made up of sugar and causes a combustion reaction when mixed with the excess oxygen. Carbon dioxide and gaseous water are released as a result of the reaction. The purple flames that arise are the result of an exothermic reaction and heat being released is the result of an energy transformation. Although there are many chemistry concepts exhibited in this…

metal surfaces are exposed to. Therefore, metal surface acquire different potential between different aerated areas. It has been found experimentally that poor-oxygenated parts are anodic. Examples:  The metal part immersed in water or in a conducting liquid is called water line corrosion.  The metal part partially buried in soil. If the metal is partially immersed in the electrolyte, the area above the liquid is more aerated and becomes cathodic area and that area which…
