To test ideas of surface-to-volumeratios, he makes a quarter pound hamburger and a quarter pound meatball and cooks them at the sametemperature. One night, Hans decides to cook a hamburger and spaghetti with meatballs. From what was observed in the potato procedure, how do the rate of diffusion and surface-to-volume ratio limitcell size? (5 points)15. Which cube would be most efficient at moving materials into and out of thecube? Briefly explain the answer. What is the surface-to-volume ratio and rate of diffusion for each potato cube from Procedure 3b? (6 points)a. Based on what thestudent learned about osmosis, provide an explanation that supports or refutes this information. People always say that leeches can be removed from the body by pouring salt on them. Provide a possibleexplanation for why the carrots weighed more at the store, based on the information learned in this lab. They also no longer seem as crisp and taut. After returning home, she weighs the carrots again anddiscovers that they weigh only 4.2 lbs. She notices that the grocerystore constantly sprays its produce with distilled water. A student purchases and weighs 5 pounds of carrots from a local grocery store. What would happen if a marine organism were placed in freshwater? (3 points)10. Use the terms iissottoniicc, hyypottoniicc and hyypeerrttoniicc in the answer. Explain what would happen to a freshwater unicellular organism if it were suddenly released into asaltwater environment.

In osmosis, which direction does water move with respect to solute concentration? (2 points)9. What extraneous variables might have affected how the results came out in the osmosis experiment? Describethree. What were the percent differences between the volumes of the potatoes in the osmosis experiment for eachsalt solution? (8 points)a. In the Spirogyra cells observed on the virtual microscope, about how many circular green chloroplasts wereseen in a single cell at 40X magnification? (2 points)6. Where in the cell are the chloroplasts located? (5 points)5. Explain why William came to this conclusion. Provide a probable name for this organism (1 point)b. William is observing a single-celled organism under a microscope and notices that it has a nucleus and iscovered in small, hair-like structures.a. Below are five structures observed in cells.

Ron Blakey is professor emeritus of geology at Northern Arizona University and founder of Colorado Plateau Geosystems Inc.1. Tim Montenyohl is a 3-D Artist and Animator at International Mapping. Slide through the timeline above to explore how the globe has changed over seven major “snapshots” in our climate history, and to see how it might look in the far future.Īlex Tait is Vice President of International Mapping in Ellicott City, Maryland. Understanding how humans are affecting Earth’s system requires a better grasp on the natural cycles and events that have shaped our planet through deep time. But scientists agree that human activity has now begun to influence the planet, changing the climate and drastically altering surface conditions.

This constant reconfiguration has been a huge driver in the development of life on Earth. Earth is a planet defined by change, swinging through periods of intense heat and deep freeze even as oceans and continents are reshaped by the actions of plate tectonics.
