Lateral geniculate nucleus

Cells signals can be mainly described as chemical, prokaryotes have sensors capable of detecting nutrients which helps them find food these signals can either be long distance or short distance some of the short distance could be found in muscle cells and a long distance can be describe as the releasing of an egg in the ovaries. Cells have protein receptors which will bind to protein signaling molecules triggering a respond in the molecules. Different receptors are specific for different…

be bounded by a plasma membrane (Biology Department,2015), and contain a nucleic acid: such as DNA, RNA, cytoplasm, and ribosomes. The things that prokaryotes will not have are organelles. Organelles can be known as the parts of the cell, such as: Nucleus, ER, Golgi apparatus, etc. There are there domains that exist: Bacteria, Archaea and Eukarya(Biology Department,2015) Archaea and Bacteria look very similar under the microscope and therefore it’s very hard to differentiate them. Therefore both…

Alchemists used to obsess over chrysopoeia, the transmutation of regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or…

When an organism is in an aquatic environment, they are required to maintain their homeostasis from the difference in salt and other particles in solution and in their cell bodies. The salinity and osmolality in an environment triggers a series of regulatory responses in the organism to maintain equilibrium. The equilibrium is essential to its cell’s life and ultimately the life of the organism. The response to maintain such equilibrium is an osmotic regulation, the regulation of the solutes in…

Eukaryotic cells are cells whose nucleus is bound by a membrane; these cells contain organelles, which are structures each enclosed within its own membrane found only in eukaryotic cells, each organelle has a specific function inside a cell. One type of organelle is a lysosome, which are the organelles that dispose of waste and toxins. Lysosomes are fluid filled sacks which range in size from 0.1 to 1.2 micrometres and contain around fifty degradative enzymes that enable it to effectively…

Bob The Blob and his dog Blobby were green cells that lived in a human named Tyler. It was very strange being a cell. Although, it was almost the same world that humans lived in, just different. For example, instead of roads, they had bloodstreams, instead of humans and their pets, everyone was a cell, just in a different form. Roads still existed and they were still called ‘roads’, or at least by the cells. If you were a human, you’d call it a bloodstream. The small world the cells lived in was…

The cell is stimulated by immune and proinflammatory responses. IkBa undergoes phosphorylation, which promotes ubiquitination and degradation, this enables the dimeric RELA to move to the nucleus and activate transcription. IkBa is involved in rocky mountain spotted fever, an infection caused by rickettsia rickettsia, a bacterium that is carried by a certain species of ticks and can spread to humans if they are bit an infected tick. This infection…

Difference Between Mitosis and Meiosis: Every multicellular organism has originated his life with only a one fertilized egg , which then maximized by the well known process of division of cell. In cell division process the cell is obtained by the already existed cell or pre existed cell stated by Ruolf Virchow in 1855. The process divison of cells is uasuall same in all of the living organisms. Division of cells is furtherly divided into two types :- 1) Mitosis 2) Meiosis Basic Difference…

Unit 18 - Genetics (Assignment 1) Task 1. Deoxyribonucleic acid (DNA for short) is genetic material that carry’s the majority of information for development growth and many other functions. DNA is located in the nucleus of a cell. DNA has a double helix structure and is formed by a series of bases these are Adenine , Cytosine , Guanine and Thymine. These bases have a basic pattern when forming DNA. Adenine will only join to Thymine when in DNA and Cytosine will only join to Guanine when in…

Animal Cell Mitosis Mitosis is defined as the division of the nucleus. In animal cells, consists of 5 major phases – prophase, prometaphase, metaphase, anaphase and telophase. Cytokinesis occurs immediately following telophase, the last phase of mitosis and is the division of the cytoplasm. Mitosis and cytokinesis are phases when the cell is actively dividing and these stages last for a very short time compared to interphase. For most of a cell’s life, it is in interphase, which is a phase…
