Lateral geniculate nucleus

definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant ways as well…

During Meiosis, chromosomes are copied once, and the nucleus divides twice, hence Meiosis I and II. Also, during Mitosis, the chromosomes are copied once as well, but the nucleus divides only once. The cells that are produced by the process of Meiosis contain only half of the genetic material of the parent cell: one chromosome from each homologous pair and one sex…

The nucleus, controlling all of the cell's activities and containing its genetic information, remains the most important organelle of the cell today. Although the first observations of the nucleus can be dated back to the 1700s, Robert Brown is often the man given credit for its discovery. In 1831, he noticed an opaque mark in a plant cell. Brown was not aware at the time, but he had sparked thought for many scientists. Soon it was discovered that the nucleus could be found in more than just…

Sickle Cell Anemia is an inherited trait from a parent that causes victims to have their blood cells turn into sickle looking shapes. Their many names or it including HbS disease Hemoglobin S disease, Hemoglobin SS disease. To get this disease, the offspring has to to get the trait from both the mom and dad in order to have it. You can’t get it like the flu, you can only get by inheriting it. There are prenatal tests for Sickle Cell Anemia which means they test babies before they are born with…

in a house with people who persistently disregarded the rules and my well-being. They turned my simple apartment into a party house for the entire school to destroy against my will. Then in my junior year, I tore my ACL, my medial meniscus and my lateral meniscus, pulling me out…

POP! Your ACL just snaps in half. The pain is unbearable. It feels like your knee is just hanging because nothing is holding the back part of your knee together. You are scared to get the MRI results back because it is a huge setback. “You’ve torn your ACL.” Those are words an athlete never wants to hear. What is Your ACL? You may be wondering what your ACL is and what it does? Your ACL is the Anterior Cruciate Ligament. It is one of the four ligaments that stabilizes your knee so there is no…

(Th1) to Th2 immune responses leads to B cell hyperactivity and the production of pathogenic autoantibodies. Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease characterized by the production of antibodies to components of the cell nucleus in association with a diverse array of clinical manifestations.…

Fossils are a large part of discovering about the past, but to understand how fossils change over time, genes also need to be investigated. These investigations are just as important as the fossils, because of how DNA can be tested through the use of embryos. During Shubin’s expeditions into the Artic, one researcher, Randy Dahn, was experimenting with the embryos of sharks and skates. He would use various chemicals on the embryos, and examine the results to see what changes that the chemicals…

Nucleus In each cell, there is one nucleus. It is in the center of the cell, and takes up about ten percent of the cell’s volume. It is a large, oval-shaped structure bound by a double membrane called the nuclear envelope. Inside the nucleus, are organelles called nucleoli, which assemble RNA and synthesize ribosomal subunits. Throughout the inside of the nucleus, is a substance called the nucleoplasm, which suspends the nucleus’ structures. The nucleus controls the activities of the cell to…

1. What other labels, like frequent flyer, exist in your surroundings that create a bias as to how we treat others? What are the consequences of labeling people? A common label that exists in everyday life is idiot, or any word that indicates unintelligence in someone. Once this word is diagnosed to someone, anything that person does that contradicts the person’s intelligence is denied by the diagnoser. Similarly, as soon as Amy’s mother was thought of as a hypochondriac, or “frequent…
