Sarah Phenix Let's explore the relationship between enzymes and pH. Learn how enzymes function, what pH really means, and how the two interact to result in optimal enzymatic activity. Enzymes belong to a class of molecules known as proteins, meaning they have one or more large chains of amino acids joined together by peptide bonds.

The job of an enzyme is pretty specific: In other words, the reaction could be completed without the addition of the enzyme, but the enzyme essentially 'discounts' the energetic cost of the reaction so that it can happen faster and with less energy. Another important thing to know about these specialized proteins is that enzymes are not consumed or changed in any permanent way by the reaction. This means that once they disengage from one reaction, they can move right on to another reaction.

An enzyme works by binding with a specific substrate the molecule that will undergo change at a place on the enzyme called an active site.

I had the brilliant idea that I would show my students how to factor using algebra tiles before we started using the box method for factoring. My students were frustrated. And, it was the equivalent of throwing away a day of class time. I wouldn't even classify it as a productive struggle. So, the next day, I won their hearts back by showing them the box method.

For example, if you want to become more compassionate, thinking compassionate thoughts may be a start, but giving tzedaka charity will get you there.

August 15, at 3: By relativity, only gravity can compress space and slow down time. Now you seem to say there is this great process that can expand space and speed up time in the process too which by the way sounds like antigravity to me. If we can see some of that in the lab, that would be great. Also I find it is hard to say and understand that the early universe is smaller.

How is that exactly defined? Using current space and time as reference to gauge past space and time is confusing the matter further… John Campbell August 16, at At least, in the context of the Big Bang, universal symmetrical expansion.

In , 11 Australian commandos , all white, disguised themselves as Malay fishermen by dyeing their skin brown and boarding a fishing boat. They sailed through 2, miles of Japanese-controlled ocean from Australia to Singapore. At one point they even traveled right alongside a Japanese warship without them noticing anything strange which was good, because none of the commandos could speak Malay.

They then took canoes right into Singapore Harbor, where they blew up seven Japanese ships before escaping. So racism is OK as long as you have plenty of bombs and canoes. Somehow, this totally worked, and she snagged the plans to a fort and the identities of some Confederate spies before " escaping " back to Union lines.

Your independent source for Harvard news since Features The Way We Eat Now Ancient bodies collide with modern technology to produce a flabby, disease-ridden populace. Spurlock recorded the results on camera for his film Super Size Me, which won the Best Director prize for documentaries at this year's Sundance Film Festival. My blood sugar skyrockets, my cholesterol goes up off the charts, my blood pressure becomes completely unmanageable.

The doctors were like, 'You have to stop. Spurlock's total immersion in fast food was a one-subject research study, and his body's response a warning about the way we eat now. Dun Gifford '60, LL. Everywhere in the world, the richest people build the biggest homes, but as the world's wealthiest nation, the United States is also building the biggest bodies. It's hardly cause for patriotic pride. Many foreigners already view Americans as rich, greedy over-consumers, stuffing themselves with far more than their share of the planet's resources, and obese American travelers waddling through international airports and hotel lobbies only reinforce that image.

Yet our fat problem is becoming a global one as food corporations export our sugary, salty, fatty diet: Beijing has more than a hundred McDonald's franchises, which advertise and price the same food in the same way, and with the same level of success. Two-thirds of American adults are overweight, and half of these are obese. Overweight means having a body mass index, or BMI, of 25 or greater, obese, 30 or greater:

Certain vocal intonation speech variations if body language is extended to cover everything but the spoken words also fall within this environmentally determined category.

Body language - basics and introduction Body language is a powerful concept which successful people tend to understand well. The study and theory of body language has become popular in recent years because psychologists have been able to understand what we 'say' through our bodily gestures and facial expressions, so as to translate our body language, revealing its underlying feelings and attitudes.

Body Language is also referred to as 'non-verbal communications', and less commonly 'non-vocal communications'. The term 'non-verbal communications' tends to be used in a wider sense, and all these terms are somewhat vague. For the purposes of this article, the terms 'body language' and 'non-verbal communications' are broadly interchangeable. If you carry out any serious analysis or discussion you should clarify the terminology in your own way to suit your purposes.

Does body language include facial expression and eye movement? What about breathing and perspiration? And while tone and pitch of voice are part of verbal signals, are these part of body language too? It's a matter of interpretation. A good reason for broadening the scope of body language is to avoid missing important signals which might not be considered within a narrow definition of body language.

Nevertheless confusion easily arises if definitions and context are not properly established, for example: Mehrabian's research findings in fact focused on communications with a strong emotional or 'feelings' element. Care must therefore be exercised when stating specific figures relating to percentages of meaning conveyed, or in making any firm claims in relation to body language and non-verbal communications.

And science backs that reputation up: According to one study , Match. It does a decent job, but not an outstanding one. But without the full sophistication of that algorithm, it often matched our tester with people based on meaningless similarities: The site may be better suited to the user who wants to browse matches on their own and decide for themselves whom they consider compatible.

This has been a crazy week because I've been spending almost all of my spare time prepping for a 2. The participants will actually be designing their own notebook pages during the workshop, so I've had to put a lot of time and thought into how to make our time productive and make sure people leave with an INB that they are proud of. I'm looking forward to sharing my presentation slides and documents in a couple of weeks once I've had time to tweak them and perfect them.

Today, though, I want to share about this week's puzzle table happenings. It's a short, 4-day week due to Martin Luther King, Jr. And, I was so frazzled on Tuesday that I never got around to putting out this week's puzzle. So, yesterday was the first day for this puzzle on the puzzle table. With only two days of student attention so far, it has been attempted by several and solved by one pair of students I don't even have in class this year.
