55. a) Cuticles on the outermost layer of angiosperms are clear, which allows for light to pass through. The leaf is shaped in a way that will allow it to absorb more sunlight and be more efficient. Photosynthesis takes place in the spongy parenchyma and the palisade parenchyma. In order to obtain food, it is controlled by the stoma which controls the passage of gas and water.…
Choose an appropriate number scale for the Y-axis and label it Number of Infections. Choose an appropriate number scale for the X-axis label it Number of Exchanges.…
The purpose of the lab is to discover what happens when someone executes a series of procedures, beginning with copper metal.…
Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts, enzymes work by lowering the activation energy for a reaction, thus dramatically increasing the rate of the reaction. As a result, products are formed faster and reactions reach their equilibrium state more rapidly. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts in that they are highly specific for their substrates. Enzymes are known to catalyze about 4,000 biochemical reactions.…

For each onion, make a solution consisting of one tablespoon (10 ml) of liquid dishwashing detergent or shampoo and one level 1/4 teaspoon (1.5 g) of table salt. Put in a 1-cup measuring cup (250 ml beaker). Add distilled water to make a final volume of 100 ml. Dissolve the salt by stirring slowly to avoid foaming.…

The aim of this experiment is to measure and calculate the resonance frequency in different ways. Meanwhile, there is a requirement to use the apparatus proficiently. For the last part of the experiment, there is a demand to analyze the phenomenon and get a better understanding. Moreover, from this experiment, we can understand the principle of this experiment and learn some circuit knowledge.…
Introduction: All life and existence makes an unavoidable journey towards an ultimate end. Immortality is a mythical unattainable existence, barred by the presence of entropy. Mortality is a constant found in everything that was, is and will be.…
Enzymes Introduction This study allows the investigation of enzymatic reactions behavior. An enzyme is a protein catalyst reaction by lowering the activation energy required for that reaction. The enzyme is unaltered at the completion of the reaction.…
Obeserve under low power and draw what you see in your notebook. This slide shows you the spicules, wich make up the support system of the sponge. They are produced by amoebocytes and come in a variety of shapes: needle, multipronged '' jack,'' hooked or barbed. The shape of the spicules is used to classify sponges.…
