The amount of energy at each trophic level in an ecosystem decreases as it moves through the ecosystem. Typically, only about 10 percent of the energy at one trophic level is transferred to the next level. The remaining energy is lost through metabolic processes as heat.

Suppose that, in the ecosystem modeled above, 150,000 kcal (kilocalories) of energy are contained within green plants. Assuming that the amount of energy transferred from one trophic level to the next is exactly 10 percent, determine the following amounts of energy in the ecosystem.

Answer:

Explanation:

Energy transferred to next trophic level=10%×150,000kcal

=10/100×150,000

=15,000kcal

The amount of the energy in the ecosystem should be considered as the 15,000kcal.

Since there is  150,000 kcal (kilocalories) of energy are contained within green plants.

And, 10 percent of the energy at one trophic level is transferred to the next level.

So here the amount of energy be like

= 10% of 150,000

= 15,000 kcal

Hence, The amount of the energy in the ecosystem should be considered as the 15,000kcal.

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples in these videos. Now you will write a 2-3 page discussion of protein denaturation putting all that together Make sure you cover both the academic side (lecture knowledge) and practical side (what is done and observed in the lab). Make sure the answers to the following questions are contained in your report. Do NOT just answer them separately, but rather incorporate them seamlessly in your writing. This is a very broad topic, so comprehensive coverage is hardly expected, but you should demonstrate a good beginner's understanding. As usual, reference any and all resources you use.
a. What are the various levels of organization that any protein structure may have that gives it its 3-dimentional shape?Which of these changes during denaturation?
b. For each change made to a protein solution that you have seen or read about how might it affect the interactions that are involved in a protein's shape?
c. What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?
d. If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)
e. For changes that precipitate a protein, are some more likely than others to be denaturation?
f. Etc. If you find one aspect of what you've see more interesting, go ahead and learn more and expand that section of your report and keep the other sections more basic.

Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.

Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?

A. The steel wool should be burned inside of a sealed jar or other closed system.

B. The steel wool should be burned over a long period of time (at least two hours).

C. The steel wool should be burned in a room that is at room temperature (20–25°C).

D. The steel wool should be burned in its entirety so that no iron is left in its original state.

To approximate the actual concentration of enzymes in a bacterial cell, assume that the cell contains equal concentrations of 1,000 different enzymes in solution in the cytosol and that each protein has a molecular weight of 100,000. Assume also that the bacterial cell is a cylinder (diameter 1.0 m, height 2.0 m), that the cytosol (specific gravity 1.20) is 20% soluble protein by weight, and that the soluble protein consists entirely of enzymes. Calculate the average molar concentration of each enzyme in this hypothetical cell.

For over a decade, farmers in the U.S. have been planting genetically modified crops. An example of one of these crops is corn that is resistant to weed-killer. This makes it so that no corn is lost due to contact with herbicide meant to kill weeds. While this is seen by many as a positive development, others see it as a cause for concern. What is one possible negative side effect of planting genetically modified corn?
