The fungus develops in the root collar area of the tree. It travels underneath the bark by forming distinctive white mycelial fans and rhizomorphs. White mycelia fans are mats of irregular fan shaped mycelium. It grows between the wood and bark and girdles it, causing the separation between the two. The mycelia releases biopolymer degrading enzymes that allows the fungi to penetrate the bark and is used to break down the wood. The secretion of enzymes and with the separation between the wood and bark, causes the death of the tree. After decomposing, the mycelium fans leaves an impression in the resign saturated inner side of the bark.

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.
The sixth lab I completed in Biology 101 taught me how autotrophs (self-feeders) and heterotrophs (other-feeders) make organic food molecules by using photosynthesis. Photosynthesis uses the energy from the sun and it is captured and stored in the chemical bonds of organic molecules. The sunlight consists of different wavelengths of light. In plant chloroplasts, they have different pigments that capture different wavelengths of light. Light capturing pigments in green plants are called chlorophylls and these absorb all the colors of light except green, which is mostly reflected. To separate molecules from each other according to their solubility in a particular solvent is done by the process of chromatography. This basically means that polar
Growing up on a Navajo reservation in Northern Arizona, White-Kaulaity never heard about parents reading to their children. White-Kaulaity was surprised to hear her former college peers talk about how their parents use to read to them. She grew up seeing parents read to their children on television.
Every year, thousands of people of all ages are diagnosed with leukemia and other life-threatening diseases. Many of them will die unless they get a bone marrow or cord blood transplant from a matching donor. Seventy percent of people do not have a matching donor in their family and depend on the Be The Match Registry to find a match to save their life. The National Marrow Donor Program, which operates Be The Match, is an Institute Award for Excellence winner (Balanced Scorecard Institute, 2016). But. The not-for-profit organization matches patients with donors, educates healthcare professionals and conducts research so more lives can be saved. During the summer of 2006,
You may have heard of this so-called thing called a ‘white girl.’ What exactly is this creature? Well . . . they are swarming across the internet, high school hallways, and college campuses. These girls are so basic that they are taking over the world faster than Donald Trump and Daniel with the white Vans. Let me show you how to spot a “Basic White Girl” as I sip my skinny vanilla latte with soy milk no foam, from Starbucks.
Though the beetle chooses the victim, it is the fungus it carries, Grosmannia clavigera, that delivers the fatal blow (Safranyik and Carroll 2006). Working in tandem with the insect, the fungus spreads across the surface of the trunk, dismantling all defenses. So refined is this relationship that the beetles store the fungus in specialized containers. Sap, which trees use to wash out offending beetles, crystallizes, forming a “pitch cap” characteristic of infected trees. Cut off from nutrients, the host begins to wither away. It can be a slow process, with some trees standing, in limbo, for up to a decade.
Declining trees very often fall victim to insects that feed on their woody tissue, making their condition worse. They are referred to as boring insects, and they make tunnels through the bark of trees while in their larval stage. When they reach the sapwood of the tree they feed on the nutrients that the tree is transporting to and from its branches. This drain on the energy of the tree causes a failure to thrive, and eventually death by starvation. If the tunneling is prolific, the structural integrity of
Blood is the most commonly tested lab sample. In order to identifying health problems and diagnose diseases, tests are often performed to determine how its composition compares with normal values. These tests commonly include hematocrit, hemoglobin, red and white blood cell counts, WBC differentials, RBC indexes and so on. In this lab students will measure hematocrit and perform manual and electronic count of red and and white blood cells as well as determine the white blood cells differentials. Hematocrit is used to determine the pack cell volume. White blood cells help fight infections by attacking bacteria, viruses, and germs that invade the body. A WBC count can detect hidden infections and undiagnosed medical conditions. The number of
Compromised Wood: In some cases, the exposed wood underneath the bark may be soft, decomposing, or riddled with fungi. No matter the symptoms, a diagnosis from an experienced arborist like Kruger Arborists will help you determine the safest course of action for your property.
Bones have tons of information, facts, sections, vessels, and cells. There are many different types of bones according to shape: long bones, short bones, flat bones, irregular bones. Long bones, like the femur, are found in arms and legs. Short bones are cube like and mostly found in wrists and ankles. Bones are covered with periosteum, a tough connective tissue that contains blood vessels. These vessels transport blood and nutrients to nurture bone cells. Also inside the cell are two types of marrow, red and yellow. Bone marrow is soft, spongy tissue found in hollow spaces inside bones. Red bone marrow is made of mainly hematopoietic tissue while yellow bone marrow is made of fatty tissue. These two tissues give marrow its color, vascularity,
White Night was initially considered in Paris in 2002 and stimulated by Paris' Nuit Blanche and the international system of White Night programs the world over around 20 cities in the world. It is one of the biggest art festivals that celebrate in summer. The white night in Saint Petersburg is mostly famous for remarkable fireworks and scarlet sails, also known as different names such as White Night, Light Nights. White Night Melbourne is Australia's most celebrated social occasion and the famous cultural festival. White Night Melbourne was initially arranged in 2013 and was a moment accomplishment with 300,000 individuals getting a charge out of the throughout the night occasion. It was the National and international artist from all over the
Bucculatrix ainsliella is a foliage-feeding lepidopteran species that causes defoliation on oak trees, specifically red (Quercus rubra) and black (Quercus velutina) oaks. The first instar larval stage are leafminers, which burrow into the leaf and consume the nutrients between the layers of the leaf. Once they progress into the final instar larval stage they start to defoliate the trees. This stage of Bucculatrix ainsliella consume the external underside of the leaf, leaving the veins, which causes the leaves of the oaks to become less efficient in producing photosynthate (Baker 1972; Gelok et al. 1998; Klass 1985; Van Nieukerken et al. 2012). At the end of the final instar larval stage, they build 3 millimeter
Catching a cold, flu, or nausea is very common, but where did it come from? Germs are everywhere on countertops, doorknobs, in laundry and in bathrooms. One of the most common places to find germs are on the hands. There is not just one type of germ, there are many such as protozoa, fungi, viruses, and bacteria. Protozoa are one-celled organisms that love moisture and often spread diseases through water. Some protozoa cause intestinal infections that lead to diarrhea, nausea, and belly pain. Fungi are multi-celled plant-like organisms. Unlike other plants, fungi cannot make their own food from soil, water, and air. Instead, they get their nutrition from plants, people, and animals. They prefer to live in damp, warm places which is why athletes
