The Western Honey Bee and its twenty sub species have been extensively spread across the planet due to economic benefits relating with pollination and honey production. Honey bees live in colonies and split the division of labor among individuals. There are three castes of Western Honey Bees: Workers, Drones, and Queens (Krell 1996). Worker bees are non-reproductive females that make up the largest group in the colony. They specialize in the collection of pollen/nectar and feeding the young.…

glycoproteins. Next, viral glycoprotein D, which is associated with glycoprotein H and L, binds a coreceptor, and the viral envelope fuses with the cell membrane, releasing the capsid and tegument into the host. Tegmental protein VHS disassembles cytosolic ribosomes and digests RNA, thwarting host protein production. Cellular microtubules ferry the capsid to nuclear pores where tegmental proteins facilitate the transfer of viral DNA into the cell nucleus. In the nucleus, the viral dsDNA becomes…

The nature versus nurture argument is, and has been, one of the most hotly debated topics in modern science for decades. The argument of whether humans start out as a “blank slate” or Tabula Rasa, as opposed to being predisposed with certain environmental effects out of their control transcends even natural science and enters into the realms of philosophy and psychology. It is nearly undeniable that the ideas of Mendelian inheritance are sound theories, yet the argument for…

2. The element being described is Sodium its symbol is Na it has an atomic mass of 22.989769. It has an atomic number of 11. This element has 11 protons, 11 protons, and about 11 neutrons. Protons have a positive charge, electrons have a negative charge, and neutron have a neutral charge. Electron shells are the outer parts of an atom containing the electrons. Valence electrons are electrons in the outermost shell. Valence electrons tell us whether an atom shares, transfers or receives electrons…

the bacteria could be resistant to that particular drug. (5 pts) As the name implies 50s subunit protein synthesis inhibitors such as erythromycin inhibit protein synthesis by binding to the 50S subunit of the 23S rRNA molecule of the bacterial ribosome. This ultimately acts to block the exit of the growing peptide chain. It should be noted that gram+ bacteria more effectively accumulate erythromycin than gram negative bacteria thereby making it more effective in this group of bacteria.…

chemicals from planet Earth around 4 billion years. One of the most simple and primitive cells, the E. coli cell, is still vastly complex with a detailed structure. An E. coli cell must contain a capsule, a cell wall, plasma membrane, cytoplasm, ribosomes, plasmid, pili, bacterial flagellum as well as a nucleoid. The idea that one of the most primitive cells on Earth appeared spontaneously from inert chemicals out of chance opposed to the idea of the creation of a primitive yet complex cell from…

through binding of BAX preventing it from degrading the mitochondrial membrane that result in caspase-induced apoptosis. Furthermore, activation of AKT pathway signals Rheb that triggers mTOR activation translation factor S6K, which binds to the large ribosome subunit and promotes RNA translation (Davis et al., 2014). This suggest that AKT activation enables cell proliferation by inducing increased protein translation and cell growth. The activated AKT pathway also promotes phosphorylation of…

unigenes) processes. The molecular function classification showed a predominance of the ATP binding category (4,689 unigenes), followed by structural constituents of the ribosome (2,828 unigenes) and zinc ion binding (2,801 unigenes). Under the cellular component category genes coding for proteins integral to membrane (3,966 unigenes), ribosome (2,578 unigenes) and nucleus (2,058 unigenes) were observed to be highly…

Neutral community theory, also known as the unified neutral theory of biodiversity and biogeography was set-forth in literature in 2001 by Stephen Hubbell however it draws largely upon pre-established, and widely accepted, ecological theories of island biogeography (MacArthur and Wilson, 1967). The original model proposed by MacArthur and Wilson was constructed to account for variation in the composition of birds found in different sized areas as well as their relative abundance and…

Body Planes, Regions, Cavities, and Directional Terms The fundamentals of learning the body in the medical field are body planes, regions, cavities, and directional terms. First up are the body planes, which the definition of a body plane is simply a two-dimensional surface. The dimensions of the body plane are both of length and of width and the body planes are used to describe the different locations that are located in the body or are just used for the point of location. There are three…
