Virtual Fetal Pig Dissection | Whitman College (philippe) Welcome to the Whitman College Biology Department's Virtual Pig Dissection (VPD)! This site is designed as a supplement to laboratory dissections exploring introductory mammalian anatomy and physiology — it is basic and many details have been omitted for clarity. We hope that it is suitable for AP Biology students or for students of introductory anatomy and physiology at the college level. We have revised this site to improve the learning experience and accessibility. Within this site, you can navigate to any chapter from the links at the left. Pascaline On your bike: how muscles respond to exercise We all know that exercise makes us fitter and healthier – but what changes take place in our cells to make this happen? Next time you are working out in the gym, or pounding the streets running or jogging, ponder this: the idea of ‘muscle memory’ – that today’s exercise has effects on our muscles years from now – has never been demonstrated scientifically. Does it really exist, and if so, how does it work? These are some of the questions we hope to answer in our on-going research, which aims to pin down the changes that occur in muscles when we exercise, and how our muscles ‘know’ to respond differently to, say, endurance training as opposed to strength training. Helping us to investigate these questions is a large team of volunteers. We assess the fitness of our volunteers before and after participation in the studies by measuring their maximal oxygen uptake. Of course, we already know that regular exercise produces health benefits. Building mitochondria Epigenetic factors Acknowledgement
problème obésité : Persuasive Games -Fatworld (laura philippe) Fatworld is a game about the politics of nutrition. It explores the relationships between obesity, nutrition, and socioeconomics in the contemporary U.S. Fit or Fat? In the last two decades, obesity has soared in the United States. Public and private organizations have mounted ongoing efforts to change Americans’ behavior toward nutrition and exercise. More importantly, these efforts assume that our obesity crisis is caused solely by lack of self-control: if only everyone would choose to eat right and exercise, the problem would go away. Fatworld is a videogame about the politics of nutrition. Existing approaches to nutrition advocacy fail to communicate the aggregate effect of everyday health practices. You can choose starting weights and health conditions, including predispositions towards ailments like diabetes, heart disease, or food allergies. Interested in politics?
A Serious Game on Biodiversity in Wheat Farming | KTM Advance April 28, 2014 A Serious Game on Biodiversity in Wheat Farming Lu, the leading French cookie manufacturer, further confirmed its desire to minimize the company’s impact on the environment by creating LU Harmony. This new wheat network, created in partnership with French farmers, favors biodiversity and guarantees quality wheat farming. In 2010, KTM Advance created a serious game to allow young players to learn about the sustainable development LU defends and dive into the wheat field ecosystem. They also learn how to grow quality wheat and maintain local biodiversity. The “Harmonyculteurs,” or “Harmony Farmers,” deals with complex information in a fun and accessible way.

The lifeblood of the colony is fresh green leaves - the resource the player must gather in order to grow the colony and trigger the flying ant’s nuptial flight.
Endurance exercise 'interferes with heart rhythm' Pascaline Athletes beware - endurance training may make it more likely that you will need a pacemaker, scientists believe. A British Heart Foundation team found exercise in mice triggers molecular changes in the part of the heart that generates its natural beating rhythm. This may explain why elite athletes have low resting heart rates and more risk of heart rhythm disturbances, they told Nature Communications. However, the benefits of exercising still outweigh any risks, experts say. Super-fit Endurance athletes are generally very fit. Yet, paradoxically, they are more likely to have heart rhythm disturbances, known as arrhythmias, especially as they get older - although the risk is still small. Experts have suspected that this is because long-term training for extreme endurance events such as marathons and triathlons slows the heartbeat down. Cyclists Sir Chris Hoy and Miguel Indurain reportedly had resting heart rates of 30 and 28 beats per minute. How to exercise
1ère ES/L : Food Preservation Methods: Canning, Freezing, and Drying (Nico&Camille) You can preserve foods inexpensively by using canning, freezing, or drying techniques. Modern-day food preservation methods, such as water-bath canning, help you can and preserve with ease. After you understand the basic procedures for a food preservation method, you'll just need to concentrate on preparing your recipe. About canning food Canning is the process of applying heat to food that’s sealed in a jar in order to destroy any microorganisms that can cause food spoilage. Although you may hear of many canning methods, only two are approved by the United States Department of Agriculture (USDA). Water-bath canning: This method, sometimes referred to as hot water canning, uses a large kettle of boiling water. Don’t confuse a pressure canner with a pressure cooker, which is used to cook food quickly. Older canning methods are unreliable and, for that reason, aren’t used or recommended today for home-canning. About freezing food Here are three things to help you avoid freezer burn:
audio et texte en anglais sur le tabac (laura et philippe) Tobacco by Claire Powell and Dave Collett What’s in a cigarette? What’s in a puff? Tobacco smoke contains about 4,000 chemicals. Some of which are harmful, others deadly. Tar Tar, a mixture of chemicals such as formaldehyde, arsenic and cyanide, can cause serious lung diseases. Nicotine Many people are unaware that nicotine is more addictive than heroine. Carbon monoxide Carbon monoxide is a poisonous gas formed when a cigarette is lit. From seed to smoke What do tomatoes and tobacco have in common? Seeds and fertiliser are often provided by British American Tobacco. Harvest In most countries harvesting is done by hand. Curing There are four main methods. Air-cured tobacco is hung in unheated, ventilated barns until the tobacco dries and the tobacco leaf becomes a light to medium brown colour. Flue-cured tobacco is made when heat is introduced into a barn through pipes from a furnace outside. Sun-cured tobacco leaves are hung out on racks and exposed to the sun’s rays.

Lucie Lt Reconstitution d'un paysage ancien La région Charolaise au Trias était quelque peu différente de ce que l’on connait aujourd’hui : de vastes plateformes lagunaires voyaient s’ébattre quelques dinosauriens de bonne compagnie là où s’ébrouent actuellement les vaches blanches mondialement connues. Un ensemble d’indices sédimentologiques relevés dans une ancienne carrière permet de reconstruire progressivement le paysage et le climat de l’époque, dans une démarche basée sur le principe d’actualisme. Le site présente des photographies des indices relevés, des photographies d’indices actuels comparables, avec les mécanismes qui en sont à l’origine, et des pages résumant "ce que cela nous apprend". Cette activité permet de développer les compétences : prise d’informations simultanée dans des documents de natures différentes (texte et image), mise en relation de données issues de documents différents. Ces compétences sont mises en jeu à un niveau relativement élevé, vu le nombre d’informations à gérer simultanément.
