Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

Enrich Garden Soil in 4 Ways Plants rely on proper soil conditions to give them nutrients and minerals, and sometimes the ground is just depleted of these elements. This can be due to several factors, including the plants that have been grown in the past. Some plants add to the quality of the soil, and many plants can actually drain soil of those all important nutrients and minerals. There are things you can do to improve the quality of your soil to ensure that next year's garden has a better chance of success. It is best to start preparing soil in the fall for the spring growing season. That way, your amendments have the winter to break down and enrich the soil Fertilizer One of the best ways to improve soils nutrient content is by adding organic fertilizer. Compost Adding compost will always improve soil quality. Wood Ash If you have a fireplace, you can use some of the left over ash to add to the soil. Biochar is charcoal that is made in a controlled environment. Green Manure

Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon The size of the carbon atom is based on its van der Waals radius.

Fertilizer Friday Composting IV -- pH It's Friday, and that means a visit to Fertilizer Friday over at Tootsie Time.Check out her blog party and see what other people have blooming in their gardens. This is my fourth post in my series about Composting. You can read the others here: Composting I -What is Compost? Composting II -Getting Started Composting III -What to Compost Composting Q & A This week I am going to talk about pH. I remember the first time I was introduced to the concept of pH. I can still sing the jingle, but I didn’t have a clue what pH balance meant, and I venture a guess that neither did most of the population. Then, in the 80’s I worked at a swimming pool. We had to test the chlorine level and the pH level every hour, and write the numbers down on a little chart. Once a day, the maintenance guy would take the chart go and fiddle with the knobs and switches in the control room. I still didn’t have any idea what pH was, I just knew that it had something to do with shampoo. But it’s more than just that.

Cryo-electron microscopy wins chemistry Nobel : Nature News & Comment Left: Marietta Schupp/EMBL. Centre: Jorg Meyer. Right: LMB-MRC. From left: Jacques Dubochet, Joachim Frank and Richard Henderson helped to develop cryo-electron microscopy. The 2017 Nobel Prize in Chemistry has been awarded for work that helps researchers see what biomolecules look like. Jacques Dubochet, Joachim Frank and Richard Henderson were awarded the prize on 4 October for their work in developing cryo-electron microscopy (cryo-EM), a technique that fires beams of electrons at proteins that have been frozen in solution, to deduce the biomolecules’ structure. For decades, biologists have used X-ray crystallography — blasting X-rays at crystallized proteins — to image biomolecular structures. Imaging solutions In the 1970s, Henderson, a molecular biologist who works at the MRC Laboratory of Molecular Biology in Cambridge, UK, and his colleague Nigel Unwin were trying to determine the shape of a protein called bacteriorhodopsin.

3 formas de crear un juego de laberinto en PowerPoint Pasos Método 1 de 3: Crear un botón de acción personalizado 1Abre PowerPoint. Anuncio 2Agrega un título y un subtítulo. 3Haz un menú rápido agregando un botón de “Jugar” y otro de “Instrucciones”. 4Construye lo siguiente (lo cual se usará en el juego):FigurasBotones de accionesBotones personalizados 5Dibuja un botón de acción, llenando toda la diapositiva. 6Ahora haz una diapositiva de “Game over”(para cuando alguien pierda). 7Regresa a la diapositiva donde hiciste el botón de acción. 8Haz clic derecho en el botón. 9Haz clic en la pestaña que dice “Acción del mouse”. 10Coloca un hipervínculo hacia la diapositiva de “Game over'. 11Cambia el color de relleno y contorno a blanco para que las personas no vean dónde está. 12Haz un laberinto con las figuras predeterminadas. 13Guarda el archivo. Método 2 de 3: Usando imágenes para bloquear los caminos Método 3 de 3: usando la configuración de acciones Consejos ¡Las animaciones se ven muy bien en el juego! Advertencias
