Biomass Pyramid Online Biology Tutors Tutorpace

Biomass Pyramid Online Biology Tutors Tutorpace Food chains involving various living organisms in a community can also be represented in a graphical manner by drawing pyramids called ecological pyramids. An ecological pyramid is the graphical representation of a specific parameter (such as number, biomass, and energy) of a food chain. Ecological pyramids have various levels. The producer level is represented by the base of the pyramid. And as the trophic level increase the pyramid goes on tapering upwards. The carnivores are on the top of the pyramid. Biomass is the total weight of organisms per unit area. The graphic representation of biomass of organisms of the successive trophic levels of an ecosystem in the form of a pyramid is called pyramid of biomass. In most ecosystems the biomass at the successive higher levels decreases. For example, in a forest ecosystem, there is a gradual decrease in biomass of organisms at successive food levels from producers to the consumers. In most of the ecosystems, the pyramid of biomass is upright. It is because of the biomass at the successive higher levels of the ecosystem decreases. For example, forest ecosystem. In a forest ecosystem, there is a gradual decrease in biomass of organisms at successive food levels from producers to carnivores. In certain ecosystems, the pyramid of biomass is inverted .Example: deep water bodies. The pyramid of biomass for a lake ecosystem is inverted because, the biomass of a number of short lived producers (standing crop of phytoplankton) at a particular time is less than the biomass of large standing crop of zooplankton.

Subtracting Rational Expressions Online Tutoring

Subtracting Rational Expressions Online Tutoring Rational expressions are the expression which consist of constants and variables combined together by addition, subtraction, multiplication or division. The coefficients of the variables (the numbers beside the variables) are usually in the form of fractions. Subtracting rational expressions involves combining the like terms together and if there are fractions involved, we have to make sure that they are of the same denominator. If the rational expressions are not of the same denominator, then we have find their least common denominator and then simplify the expression accordingly. Example 1: Subtract the given two rational expressions:(5x/6) (2x/3) In order to subtract the rational expressions, we have to first find their common denominator. The LCM of 6 and 3 is 6. Here the first term, 5x/6 has the denominator as 6 so the term stays the same. For the second term, multiply the numerator and the denominator by 2 to get the common denominator 6== (2x* 2)/ (3* 2)= 4x/6 Now, 5x/6 4x/6 = (5x- 4x)/6 = x/6. Example 2: Subtract the given two rational expressions: (3a/2) (4a/5) In order to subtract the rational expressions, we have to first find their common denominator. The LCM of 2 and 5 is 10. For the first term, multiply the numerator and the denominator by 5 to get the common denominator 10-(3a* 5)/ (2* 5) = 15a/10. Similarly, for the second term multiply the numerator and the denominator by 2 to get the common denominator 10== (4a* 2)/ (5* 2) = 8a/10 Now we have, 15a/10 8a/10= (15a- 8a)/10= 7a/10.

Aircrash Survivor Stories Preparing For Your ICAO English Exams

Aircrash Survivor Stories Preparing For Your ICAO English Exams When we think about air crashes, we generally think of the worst case scenario â€" fatalities. However, there are also survivors of these traumatic and surreal events with vivid stories to tell and valuable lessons learned.The UK Guardian featured a series of interviews with survivors of air disasters in its newspaper in February 2009.  These interviews were  carried out by Ros Anderson and Charlotte Northedge .Let’s look at one of these stories and answer the questions that follow it.Interview with: Upton Rehnberg, 72Flight: United Airlines flight 232 Crash landing: Sioux City, Iowa Date: 19 July 1989Id changed on to flight 232 at the last minute in the hope of getting home from a business trip for my sons ninth birthday. I usually ask for a seat at the back, but 9A, a window seat by the left side emergency exit, had been one of the last available. If Id taken my usual seat, I would be dead.I was sitting in front of a flight attendant and, just over an hour into our journey, I le aned over to her and said quietly, The pilot is flying this plane in a very strange way. There had been a loud explosion, but an announcement had reassured us that we had lost only one engine and everything seemed to return to normal. The attendant said, softly, Hydraulics. I didnt know that everything on that plane worked off the hydraulic system, and it had lost all power.The flight attendants gave every appearance of business as usual. Then, 30 minutes after the explosion, they told us to adopt the brace position. They said we should be prepared for the worst.I still didnt think we were going to die. I assumed they would be able to get the aircraft down. It was quiet. I remember taking off my tie I dont know why. I put my reading glasses in my shirt pocket, tied my shoelaces and waited.I later learned that we hit the ground at 260mph; the normal landing speed is around 150. The right wing hit the ground first and started a fire. The plane slammed down, bounced up, came back down on to its nose and began to cartwheel.The noise and impact were incredible. I couldnt hold the brace position and I bounced upright with my arms over my head. A fireball of burning fuel came through the seal of the door next to my left knee and hit me in the face. It melted the front of my Dacron shirt, burned my chest and the gap between the tops of my socks and my trousers.The plane broke into five sections and each went in a different direction. We were thrown around viciously, and I was knocked unconscious. When I came round, I was hanging upside down from my seat belt. I undid it and walked across the ceiling of the cabin to the exit. There were cables hanging down, so I held them up, letting the people behind me get out. I was just aware of the need to keep people moving so they werent blocking each other.In a plane crash, people sit around waiting for direction, but being prepared can make all the difference. Now when I fly, I wear natural fibres. Often I wear a sweatshirt w ith a hood. A man in the burns unit with me was a flight engineer, and he told me that when airline personnel are passengers, theyre taught to cover their head with a blanket in an emergency landing. But there arent enough blankets for every passenger.Dressing in a way that covers up as much of your body as possible, counting the rows from your seat to the emergency exits, knowing how to open them and moving quickly can make all the difference. You are the person you have to look to to save your life.QuestionsWhat led Mr Rehnberg to think that something was wrong with the aircraft?When the passengers were warned they should prepare for the worst what was his reaction?How was he injured in the crash?What does he say makes all the difference in the aftermath of an air crash?What is his advice to future aircraft passengers?Did you find this blog helpful?

Check out some of my favorite ways to creatively cook with cauliflower below and find your own cauli-inspiration! Cauliflower Crust Pizza Image via brit.co This is one of my favorite recipes right now as I make it at least every other week.   I am an avid pizza lover (I mean who isn’t?) but I am not a lover of all of the fat and calories hiding in those cheesy delicious pies. Instead of giving in to your pizza temptations you can make this seriously easy and delicious low-carb alternative. You simply make the crust using riced cauliflower, and you can even make several at a time and freeze them for later use. Top the crust with whatever you would like and the best part is that you don’t have to feel guilty about loading up on cheese! This is all you need for your crust: a small (emphasis on small!) head of cauliflower, one egg, some mozzarella and Parmesan cheese, salt, pepper, garlic powder, oregano, basil and crushed red pepper flakes. That’s it! Plus, whatever toppings you choose. Check out this awesome recipe courtesy of tastykitchen.com! Cauliflower Hot Pockets Image via brit.co YAS, this is so epic. Finally a healthy take on the Hot Pocket! These deliciously melty pockets are the adult version of everyone’s favorite childhood treat and they are practically guilt free.

The beauty is that the cauliflower actually resembles the taste of rice so you’ll actually feel as though you are eating fried rice. While conventional takeout inspired cauli-fried rice is never a let down, the ginger in this specific recipe kicks it up a notch. This rice has a delicious and complex flavor profile with lots of fresh ginger, onion, some soy sauce and a bit of heat from the Sriracha. And sure, you can mix a beaten egg into the mixture, but I like a fried egg on top better. Or, you can even do both. Up to you! Cauliflower Brownies Yes, you read that right!

Algebra Stress Test

Algebra Stress Test After tutoring this young man in Intermediate Algebra for a few weeks, I could see that hes really on the ball. A sharp, intelligent kid. It certainly was a joy to work with someone who is not only smart, but polite as well. I’m sure there are many like him but I’ve seen more who were not. So it goes. When we went through the problems I could see he had many concepts down pat. I watched as he solved many of the workbook problems by himself. If fact occasionally I would be stumped on something that I hadnt seen for twenty years and he would explain it to me. Now how about my tutoring skills?   The point Im trying to make is that this guy seemed to know much of what I was there to tutor him in. Of course as a high school student in second semester algebra, there were plenty of areas that he needed some explanation for. But on the whole he was doing really well. As we were wrapping up our final week of tutoring before the final exam, I mentioned to his parents how well he was doing and they told me that last semester he was doing well and helping other kids in Algebra 1, explaining to them some of the concepts they could not understand. Yet when it came time for the test he would do poorly. They could not understand the drop off from studying with other kids and then stumbling through the exam. It didnt make any sense. Suddenly I saw myself a few years ago, back in school as an older student (nontraditional they called it). Whenever I was taking a math or science course, I would seem to slowly get the ideas, as I plodded along. I would sit with a study group and be able to participate in the work we did together. Yet when exam time came, I would study all the harder, but when I sat down to take the test I would very often do poorly even though I seemed to know the material beforehand. Like many other students I would get to class early on exam day and sit there and cram like all those around me for every last minute, before the exam was handed out. What I discovered was that I did everything right until the day of the exam. That was the only thing I needed to change in order to improve my grades. What did I do instead? Nothing! Well not exactly nothing, but the one thing I did not do was study. Thats right. Up until test day I would work hard, join groups, get a tutor if the subject was too much for me. I recommend all those things. However, on test day I would make sure I had a good meal, did something good for myself, maybe exercise or go for a walk with a friend. Especially, I would meditate just before exams, rather than cram more information into my head. You see, what I realized was that all the information I needed was there days before, but as I kept frantically pushing through more information or the same information again, all I was doing was stressing me out.   So by the time I sat down for the test my head was spinning. What I found, by trial and error, was that if I do all the legwork beforehand and study real hard, get help if needed (see TutorZ.com), the only thing left to do was to relax. So on the day of the exam I would make sure I had a decent nights sleep, instead of staying up late cramming. Then I would have a good breakfast; get a little exercise and head to school. When I get to the campus I would not rush to class early to reread as much as possible until exam time. Rather I would find a nice spot on the grass some place under a tree and meditate for 15 to 20 minutes. And BAM! I’m ready for the test. Dont ask me how or why, all I know is when I used this approach for test preparation I ALWAYS got a much better grade! Always.
