Answer:
A. ecosystem, community, population
Answer:
a. PPOs are denatured at high temperature
Explanation:
Polyphenol oxidase, PPO, is one of the most studied enzymes in the food industry as it is responsible for enzymatic browning reactions in fruits and vegetables. One of the reasons why its study is important is because commercially it is undesirable, since it modifies the sensory, nutritional and in general quality properties that impair the commercialization of a product.
The importance of controlling polyphenol oxidase is that it largely determines the quality and economic value of fruits and vegetables harvested, stored and processed. Bruising, chopping and other mechanical procedures damage the walls of fruits and vegetables which allows oxygen to penetrate, resulting in darkening or enzymatic browning reactions.
Enzymatic browning can be controlled through the use of chemical and physical methods, often used in combination. The commonly used physical methods are the reduction of temperature, oxygen and the use of modified atmospheres or coating films. The use of chemical methods will depend on what you want to inhibit, be it the enzyme, the substrate (oxygen or phenolic compounds) or the products.
<span>The independent variable is the variable that does not change despite inputs. In this experiment, the independent variable is the color of mashed potatoes. The control group is what the experimental group is measured against to determine how much change there is. Plain potatoes is the control group. Number of samples is how many different opinions are taken into account. In this instance, the number of samples is equal to the number of students, or 100. There are no repeated trials. She only did the experiment one time.
The hypothesis is what the experimenter believes will happen. Gloria did not state the hypothesis for the experiment. She could have said, "I believe that students will choose colored mash potatoes than plain."
This experiment can be improved by repeating the experiment at more schools. Also, it can be improved by increasing the number of students tested.</span>
The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.
