Kidney stones are solid stone-like masses that form within the kidney and or the ureter. These solid masses are made up of salts and minerals commonly found in urine and are due to a constant build up of substances in the kidney. Depending on the size of the stone, ranging from as small as a grain of salt to as large as a golf ball, the stone may pass out of the body during urination or may get stuck in the bladder or the urethra. When kidney stones get stuck due to their large size, they may…

the cell wall has always been a known thing, however, how the pores looked under function had been unknown. That is, until 1990 when Agre became the first to discover one. Chemical signals and ion currents are also passed from one cell to the next. In 1998, MacKinnon was able to show the world what an ion channel at atomic level look like. Both of their discoveries lead to more interests and findings in the areas of bio chemistry, biology,…

each poet, that’s why Ion makes such a distinction between Homer and every other poet (531a4). Socrates believes that God instills poets with these thoughts and ideas and possesses the poet (534c3). God is the source of the poet’s motivation and inspiration (534d3). Q1ii. The dialogue is mostly concerned with knowing the poet’s thought. Ion makes it clear that he has memorized Homer’s lines when he recites what Nestor says at Patroclus’ funeral (537a8). Socrates trusts that Ion has adequately…

is electric, the two neurons will have a direct link. They will allow small ions and molecules to pass freely between the two cells. Electrical conduction will also let AP to travel from one neuron to another. If the transition is chemical, the impulse that is received will spread to the presynaptic axon terminal. There will be a change in the voltage-gated channel of calcium; this will allow the movement of the calcium ions into the terminals of the axon. This will make the synaptic vesicles to…

the rare earth metal ions (Y, Gd, Dy, Sm, Eu, Ho, Er, Tm, Tb and Lu). The first trail for synthesis of garnet Yttrium ferrite (Y3Fe5O12) was done by Bertaut and Forret in 1956 [39], this trial was followed by another one in 1957 when Geller and Gilleo prepared and investigated Gd3Fe5O12 [40]. The garnet ferrites have complex crystal structure with cubic shape. The cubic unit cell of garnet ferrites R3Fe5O12 contains 8 formula units or 160 atoms with O2 as widespread ions (96 ions). The trivalent…

Potassium ion, calcium ion, conductivity, and dissolved oxygen will be compared from Lake Mary, Colorado River Float, Lake Powell Marina, and Lake Powell Swimming locations. These 4 tests will be compared as it takes into account three popular ions found in most bodies of water (salt, calcium, and potassium), as well as the oxygen levels which is one of the most important factors to marine life. For the potassium ion test, the probe must first be calibrated. To calibrate the potassium ion probe…

The process can take place in three parts. • Filtration – This process happens in the entire nephron system. When blood goes through and into the capillary at the beginning of the nephron, small molecules, such as glucose, urea, ions and water are cleaned out and passed through the nephron tubule. The larger molecules such as blood proteins, cannot fit through the capillary wall as they are too big, therefore they stay in the bloodstream. • Reabsorption – When the small molecules are cleaned…

because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their size, charge, and how much water it is holding or attracting towards it. The channels that normally are responsible for RMP are non gated ion channels, which are normally simple non excitable cells. The ions usually moving down the…

exhalation from the body (King, 2018). Acid- Base balance are affected by hydrogen ions which are formed from the lost of electrons. When a molecule releases hydrogen ion it is determined as acid, and when it is bind with hydrogen ion it is a base. Hydrogen ion expressed in the blood is represented as pH levels, which the homeostatic level should be a pH of 7.40 ± .02. Acid- Base balance is concerned with the hydrogen ion in the blood as it…

starch, glucose, and the chloride ion molecules pass through the artificial membrane? Why or why not? Hypothesis: Tiny molecules have an easier time passing through the plasma membrane than larger molecules. Molecules that are greater than fifty atoms do not pass through the artificial membrane. This is due to its composition consists of thousands of atoms. Glucose is able to diffuse through membranes as its genetic makeup contains twenty-four atoms. Chloride Ions are also able to penetrate the…
