A.) The two most significant environmental or physical geographic factors that contributed to the development and expansion of the United states had to be the Gold Rush‚ and the Irish Potato Famine. The Irish potato famine was devistating to Ireland and laid waste to it’s population‚ but ended up spurring Irish immigration to the United States‚ leading to both growth and expansion. The gold rush that took hold in the United States was one of the biggest factors that pushed people west and lead to

AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion. Diffusion is a movement from a higher

Aspartame usually increases the muscles movement that is uncontrollable usually caused by Tardive Dyskinesia (a condition whereby an individual experiences movements that are involuntary in their lips‚ tongues‚ face and even trunk). Aspartame can affect the unborn child of a woman who has phenylketonuria in that it can cause the child to be born with conditions like impaired neurological function; a situation whereby the neurological system is not functioning the way it normally should‚ congenital

It will led the cells move randomly around to others. For this molecular movement‚ there are two results that might happen. Diffusion is one of them. Diffusion is the movement of molecules that between the high concentration and the low concentration

A. Environmental factor that contributed to the development of one early human society: Andean Civilization - The Inca Empire ran north to south in the Andes Mountain Range. It was located 50 km in land from the coast. We also know that the Inca Empire occurred during a period of major environmental change on a global scale. The most important environmental factor played in the development of the Inca civilization was the weather. Inca Empire was located in areas where weather would fluctuate depending

able to receive the nutrient in the 1 cm cell and almost all of them in the 0.5 cm cell. This is caused due to the larger surface area to volume ratio as the cell size depends on the efficiency of the material to flow in and out through diffusion. Through diffusion‚ the organelles in the cell receive all the vitally needed nutrients to survive. If there is a big surface area to volume ratio such as 1:2‚ then this process will be delayed due to the sodium hydroxide having to cover a larger distance

P2 – Factors that affect development. There are five main factors that affect a person’s development‚ they are: Genetics factors. Environmental factors. Socio-Economical factors. Life style factors. Biological factors. Genetic factors Each cell in the body contains 23 pairs of chromosomes‚ half from your mother‚ and half from your father. The chromosomes contain the genes you inherit from your parents. For example‚ for the gene that determines eye colour you may inherit a brown gene and a blue gene

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch
