My prediction is that as the concentration increases, the potato cell will lose more weight. This is because of the osmosis of water particles from the potato cell cytoplasm to the solution, resulting in a loss of weight. As the concentration decreases, the potato will lose less weight until a certain point where the osmosis of particles in and out of the potato cells will be equal. I also predict that as the salt

6. Describe several adaptations that enable plants to reduce water loss from their leaves. Include both structural and physiological adaptations.

|(2 marks) | |c. |State two symptoms that may have led the veterinarian to suspect that George was suffering from a thyroid hormone |

3. State the name and structure of the functional group for each type of biologically

7)a) You would do the Benedict’s reagent test for simple sugars and the Lugol’s solution or Iodine test for polysaccharides and starch. To test the lipids you would use the Sudan iV test and Biurets reagent test for protein.

Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab.

What sort of environment (hypotonic, hypertonic, isotonic) did the extra fertilizer create around the roots of the corn?

In eukaryotes, stored primarily in the cell nucleus. A nucleic acid using deoxyribose rather than ribose.

A. Imagine if scientists discovered a new plant, a plant they say has the potential to both save money and conserve the environment.

Based on the current conditions of the area, we hypothesis that tree survivability will be highest in elevations above 3,000 feet and below 3,300 feet, highest in slopes between 0 - 45 degrees, and highest in aspects between 0 - 33 degrees. Tree survivability will also be highest in area with the best soil, water quality, and forest health conditions for successful tree sapling growth.

Osmosis is defined as the tendency of water to flow through a semipermeable membrane to the side with a lower solute concentration. Water potential can be explained by solutes in a solution. The more positive a number is more likely it will lose water. Therefore should water potential be negative the cell the less likely it will lose water. In using potatoes the effects of the molarity of sucrose on the turgidity of plant cells. According to Clemson University, the average molarity of a White potato is between .24 M and .31 M when submerged in a sorbitol solution. This experiment was conducted with the purpose of explaining the relationship found between the mass in plants when put into varying concentrations of sucrose solutions. Should the potatoes be placed in a solution that contains 0.2M or .4M of sucrose solution it will be hypotonic and gain mass or if placed in .6M< it will be hypertonic and lose mass instead. Controlled Variables in this lab were: Composition of plastic cups, Brand of Russet Potatoes, Brand of Sweet Potatoes and the Temperature of the room. For independent variable that caused the results recorded it was the different Sucrose concentrations (0.0M, 0.2M, 0.4M, 0.6M, 0.8M, 1M). The dependent variable was the percentage change from the initial weighs to the final. The cup with .4 molarity was the closest to an isotonic solution and was used as the control group for the lab. Water potential is the free energy per mole of water. It is

The dreaded tree disease that’s one letter away from cancer. Moreover, think of canker as a cancerous sore in the tissues of the tree caused by pathogens. The Morton Arboretum defines canker” as a symptom of an injury often associated with an open wound that has become infected by a fungal or bacterial pathogen”. Again, one should take phone pics immediately to your local county agent for diagnosis. Also, if the tree is your treasure, don’t hesitate to call (and pay) a certified arborist. Certified arborists act as impromptu tree oncologists. I refer most of my clients to Mike Johnson of Horticulture Solutions. His reputation precedes him. Plus, the business is in my neighborhood! My experience has been that, of all the “bleeders” mentioned, ‘Autumn Blaze’ hybrid maple is most subject to canker. Although ‘Autumn Blaze’ boasts the most intense, amazing, scarlet fall color…it is after all, a glorified Silver Maple. (A loathed weed tree for horticulturists and gardeners in the Oklahoma City area) Stick with any Acer rubrum (‘October Glory’ has outrageous fall color too!) or our only native sugar maple, Acer saccharum ‘Caddo’. Such North American natives make the best tree selections since they perform in our Oklahoma elements and soils. Not to mention, they are ecological contributors. Meaning they don’t just sit selfishly consuming resources but support pollinators and other local wildlife. Thus, native trees are far less likely to develop diseases like

What is your favorite thing for breakfast? French toast? Pancakes? Do you like your steaming stack of French toast or fluffy pancakes with maple syrup? I thought so. Using your homemade made maple syrup will make them taste even better. So, why not go back to the basics and make you own maple syrup. Believe me, it is worth your effort. There are three basic processes involved in maple syrup production, taping and collection, reduction of sap, and canning or bottling. ??

5. Explain the reproductive mechanisms of plants in natural reproduction and artificial propagation (e.g., germination of seeds, leaf cuttings, grafting of branches onto a host tree)?
