Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

Maybe it’s because I live in Rhinelander‚ Wisconsin‚ where Brett Favre draws more of a crowd on Sunday than any religious service‚ cheese is a staple food‚ it’s sub-zero during global warming‚ current "fashions" come three years after they’ve hit it big with the rest of the world‚ and where all children by the age of ten can use a 12-gauge like it’s their job. I shouldn’t have told them I live on a farm with a barn‚ ten chickens‚ a dog‚ a canary‚ two thousand deer‚ coyotes and beautiful Silver Bass

Anthocyanins are water-soluble and are dissolved in the cell sap rather than bound to the membranes as chlorophyll is. If cell sap in a leaf is very acidic‚ then anthocyanins make the leaves a bright red color‚ but if it is less acidic the color

A vegetable is an edible plant or part of a plant‚ but usually excludes seeds and most sweet fruit. This typically means the leaf‚ stem‚ or root of a plant. The non-biological definition of a vegetable is largely based on culinary and cultural tradition. Therefore‚ the application of the word is somewhat arbitrary‚ based on cultural and/or personal views. Vegetables are most often cooked in savoury or salty dishes. However‚ a few vegetables can be used in desserts and other sweet dishes‚ such as

Stacy Hernandez Period 1 Mrs. Riley 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

What drove European involvement in the world of Asian commerce? They wanted tropical spices such as cinnamon‚ nutmeg‚ mace‚ cloves‚ and‚ above all‚ pepper. They also had Chinese silk‚ Indian cottons‚ rhubarb for medicinal purposes‚ emeralds‚ rubies‚ and sapphires. To what extent did the Portuguese realize their own goals in the Indian Ocean? They would steal goods from cargo ships delivering goods. They had ships that could outmaneuver other ships and they had on board cannons that other ships

EYMP3-4.3 Explain how to prepare and store food‚ formula and breast milk safely according to health and safety guidelines. Babies between the ages of birth to 24 months have immune systems that are still developing‚ leaving them more susceptible to germs and bacteria. Bacteria that comes in contact with an older child or adult may not have the same impact that it will have on a baby‚ which is why it is extremely important that food safety be managed diligently. food In my setting‚ food is prepared
