diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the 5 minutes given‚ giving a more pink/red color to the water surrounding the beetroot at a higher temperature‚ and at lower temperatures slowing down the molecules and making the rates of diffusion lower in colder temperatures‚ giving it a paler appearance. This explains

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

Ancient Egypt and Mesopotamia Egypt and Mesopotamia‚ although similar‚ are different as a result of one major natural resource: a river. Ancient Egypt and Mesopotamia were an agricultural based society that believed in the existence of many deities; however‚ they differed in the aspect of how they evolved as an agricultural society and whether they feared or praised their gods. Mesopotamia‚ also known as the Fertile Crescent‚ was located inside the Euphrates and Tigris River. The fertile land

Problem Question: * What effect does temperature have on the rate of Diffusion? Hypothesis: If we put the antacid in hot water‚ then it will dissolve faster than in cold water or room temperature water. Material List: * One thermometer * 3 beakers (of the same size) * 3 antacid tablets * Cup of ice * Hot plate * Paper towels * Water Procedures: Step 1: Gather materials Step 2: Label the beaker #1‚ #2‚ and #3 Step 3: Fill each beaker with the same amount of

Diffusion of Hydrochloric Acid into Different Sizes of Agar Blocks Aim: Investigating the relationship between the diffusion and the surface area to volume ratio‚ with agar and hydrochloric acid. Research Question: How does the difference in surface area to volume ratio affect the diffusion? Hypothesis: As the area to volume ratio increases‚ the time taken for a complete diffusion will also increase. Background Information: Agar is a jelly like substance and in this experiment‚ agar

Geography impacts many regions‚ but my main focuses are on Ancient Egypt and Mesopotamia. Ancient Egypt and Mesopotamia have similarities‚ but despite that‚ they also have differences. The culture‚ religion‚ and land of both regions have been impacted by geography‚ and the differences and comparasions of both will explain more of their regions background and how they were impacted over the years. First and foremost‚ Ancient Egypt has two pieces of land called the ´black land´ and the ´red land´

The change theory that could work for this proposed programme would be Rogers’ theory of ‘Diffusion of innovation’ and Lewin’s (1951) ‘Force Field Analysis’ (FFA). Rogers’ theory of Diffusion of innovation is the process of innovation communicated with participants to create and share information with one another in order to reach an equal understanding over time (Rogers‚ 2010). Rogers’ (2010) theory involved events when the change agent seeks to persuade a client to adopt an innovation. In relation

systems of Mesopotamia and Nile River Valley The ancient civilizations of Mesopotamia and the Nile River Valley varied in most aspects of society. Everything from the temples built in Mesopotamia to the technologically advanced pyramids in ancient Egypt that still stand today as historical landmarks is linked to the sovereigns that ruled these civilizations. Egyptian kings (better known as pharaohs) and Mesopotamian rulers were treated completely different. Unlike rulers from Mesopotamia‚ pharaohs

The Arise of Civilizations in Mesopotamia and the Nile River Valley The Fertile Crescent lies from the Persian Gulf to the Mediterranean Sea. The Fertile Crescent was a land named because of its good soil and its golden wheat fields. Within the Fertile Crescent was a region called Mesopotamia that the ancient Greeks had named later. This meant “between the rivers” where it was located it was between the Tigris river and the Euphrates river. In this area the world’s first civilization arose in

Factors that Affect Diffusion Biology The aim of this investigation is to prove the effect of increasing size on the efficiency of diffusion. Diffusion is the process that cells use to obtain oxygen‚ water and food. Also‚ how they lose waste substances‚ for example‚ urea and carbon dioxide. Basically‚ Diffusion is when particles move from an area of high concentration to an area of low concentration. The surface area to volume ratio of the cell is an important factor in diffusion. It is the effect
