Osmosis in Potato Cells Interpretation My results show what I predicted would happen. My prediction was that as the concentration of sucrose increased the amount of water moving in or out of the potato would change. A low concentration of sucrose solution would make the potato increase in length and mass (become turgid). A high concentration of sucrose solution would make the potato shrink (plasmolysed) We can see this occurred‚ as at 0.1mol of sucrose solution the potato’s size increased by an

Functionality At Various Ph Level Abstract Enzymes can be denatured at various ph levels in which then affects the shape of the enzymes structure and reactivity. The altering of shape causes substrates to not bind in the active site (Scott Freeman‚ Micheal Harrington‚ Joan. C Sharp‚ 2009). Amylase is used as a catalytic enzyme to determine the time period to convert starch into glucose monomers and transport into the bloodstream at different ph levels. Methods involved are

years are each given a weight of 1. c. Which method do you think is best? In this case‚ the 3 year moving average is the better method as the Mean Absolute Deviation (MAD) is only 3.042 as compared to 3.347 for the weighted moving average method. What it actually means is that each forecast missed the actual value by 3.042 units instead of 3.347 units. d. Develop a trend line for the demand for fertilizer using any computer software. e.

She belived in child-led education and learning through senses‚ and developed constructive play‚ but felt that if children were encouraged to learn skills such as drawing then they would have the skills to develop their own ideas . Montessori encouraged children to learn through participation in ‘real life’ activities such as sweeping leaves and serving meals. Montessori developed

Income Level Income level has an effect on behaviors‚ including what people buy and how much they will pay. According to Bieker‚ consumer spending forms two-third of all spending in the economy. A change in consumer income will result in consumers buying more or less of product at all possible prices and also cause a change in demand and a shift of the demand curve. If the income and savings of consumers are high (the high consumer spending level)‚ their purchase is parallel or even more expensive

1. In your own words summarize the “Social Environmental” level of the Social Ecological Model (3-4 sentences). The Social Environmental level of the Social Ecological Model deals with factors such as social support‚ social capital‚ social norms‚ and more. It is based on relationships on a larger scale than seen in the interpersonal level. It is essentially the emotional or social environment constructed by the personalities that live in an area (neighborhood)‚ or that are found participating in

What is the difference between oxidative and substrate level phosphorylation? Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce ATP. Oxidative phosphorylation uses the electrochemical gradient‚ set up by the oxidation of nutrients‚ of protons across the inner mitochondrial membrane to generate ATP from ADP. During oxidative phosphorylation‚ electrons are transferred from electron donors to electron acceptors such as oxygen‚ in

controls over variables. A laboratory experiment is a conducted under highly controlled conditions. It is the most commonly used when conducting experiments. However this only happens when the research manipulated the independent variable to see what effect it has on the dependent variable in the experiment during research. By changing the independent variable‚ and measuring the dependent variable‚ we control the confounding variables (E.V.s) others as much as possible. This allows a more reliable
