Snakes are absent 18. Yes 19. No 20. B 21. Experimental Study 22. Field Study 23. Paint the same colors in a non-ringed pattern 24. Less ringed replicas would be attacked‚ because the milk snakes would become more of a prey 25. You could do a lab experiment on the snake attacks and change what the models look like. Such as ring size or color combination to see what they attack more or less.

is formed in plant cells from glucose and is stored in the form of grains. As it has compact and insoluble molecules‚ it is an ideal form in which to store glucose molecules and these can be reformed by hydrolysis later when needed. Starch is a mixture of two types of chain (amylose and amylopectin) formed from alpha-glucose. Amylose is formed when many alpha-glucose molecules condense together forming 1‚ 4 glycosdic bonds‚ so producing long unbranched chains. These chains take up a coiled or helical

The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

Chemistry Lab Write-Up Title: Paper Chromatography of Powdered Beverage Mix Purpose/Objective: The purpose is to be able to use liquid chromatography to separate dyes in a powdered beverage mix‚ calculate the Rf values for each dye‚ and rank the polarity of each dye present. Hypothesis: If we are to use the liquid chromatography to investigate the different dyes‚ then I think the different dyes will come up having different polarities and Rf values. Procedure/Method: Draw a line across

Egg-speriment Write-up Part 1- Purpose: Why did we do the experiment? The purpose of this experiment was to understand how osmosis works and that the cell membrane is selectively permeable. Osmosis is the diffusion of water molecules through a selectively permeable membrane. Many cells cannot function without adequate water‚ so cells depend on osmosis. When a cell is selectively permeable‚ it means some substances can pass through while others can’t. Many examples of these were shown throughout

d 7. e 8. Chloroplasts store energy in food molecules. Mitochondria release the energy stored in food molecules. Plants need chloroplasts and mitochondria because they require both functions. 9. Possible student answer: One function of lysosomes is to remove debris that might clutter a cell. This is analogous to the work a cleanup crew in a factory might perform. 10. A plant cell has cell walls and chloroplasts‚ structures not found in animal cells. An animal cell has the unique structures

waterBoiling chipProcedureA Separation of a Sodium Chloride and Charcoal Mixture#1 Place 4 g of the salt/charcoal mixture in a 100 mL beaker and add about 15 mL of distilled water. Stir the mixture for about two minutes to allow the salt to dissolve. #2 Set up a filter funnel with filter paper on a filter funnel stand. Filter the mixture and collect the filtrate in a 100 mL beaker as shown in Figure 1.1. #3 Wash the solid with a further 5 mL of water but do not add this to the filtrate. Note and record
