What is meant by the First-Pass Effect of drugs? - Socratic
2016年2月29日 · first-pass effect is a process in which a drug administered by mouth is absorbed from the gastrointestinal tract and transported via the portal vein to the liver, where it is metabolized. As a result, in cases of some drugs, only a small proportion of the active drug reaches the systemic circulation and its intended target tissue.
Does First Pass Metabolism affect Intravenous (IV ... - Socratic
2016年2月28日 · No first pass metabolism does not affect medications given by the Intravenous(IV) route. Yes IV medication does completely bypass the liver. First pass metabolism means the metabolism of the drug that takes place before the administered drug reaches the systemic circulation from the place it was administered. This is applicable specially when the …
Calculations with wavelength and frequency - Chemistry - Socratic
First vibrational level for NaH lies at 1.154 × 10-20 J and the second vibrational level lies at 3.406 × 10-20 J. What is the frequency of the photon emitted when a molecule of NaH drops from the second vibrational level to the first vibrational level?
How is the carbon cycle related to a food web? - Socratic
2016年9月23日 · All living organisms are made up of carbon. Thus organisms are consuming carbon and being consumed by organisms made up of carbon. Food webs and the carbon cycle are very closely related because every living organism is made up of carbon. When a cow eats grass, it is consuming carbon. When a person eats the cow, the person consumes carbon. …
How does the boiling point affect evaporation? - Socratic
2015年5月23日 · See explanation. Boiling point and evaporation have an inverse relationship, that is, the higher the boiling point of a substance, the lower is the rate of its transformation from liquid to gas (or evaporation). When the particles of a substance (usually a liquid) is heated up, its particles absorb the energy provided thereby increasing their kinetic energy resulting to more …
Surface Area to Volume Ratio - Biology - Socratic
2017年3月17日 · The ratio between the surface area and volume of cells influences their structure and biology. Surface to volume ratio places a maximum limit on the size of a cell and can influence the environment in which an organism lives and gets nutrients.
How do resistors affect capacitors? - Socratic
2018年7月8日 · The larger the resistor , the slower the charge/discharge rate. The larger the capacitor , the slower the charge/discharge rate. If a voltage is applied to a capacitor through a series resistor, the charging current will be highest when the cap has 0 Volts across it. . (i.e. when it is first connected the full voltage will be across the resistor).
What is a P wave? How does it move? What materials can it pass …
2017年10月21日 · A p-wave is a longitudinal seismic wave. These waves oscillate particles parallel to the direction of the wave propagation (they stretch and squeeze like a worm.) It can travel through solids (crust, mantle and inner core) and liquids (outer core) at varying speeds.
What are the relative positions of the sun, Earth, and moon at the ...
2016年2月17日 · [1] New Moon: Earth, Moon and Sun lined up with the Moon coming between the Earth and the Sun. But usually the alignment is not perfect with the Moon's longitude lying a few degrees above or below the Sun's longitude. The Earth-Moon line and the Earth-Sun line are close to zero degree. However, occasionally the alignment could be near perfect leading to an …
How did Rutherford's gold foil experiment disprove the plum …
2014年4月27日 · Rutherford's experiment showed that the atom does not contain a uniform distribution of charge. > Thomson's plum pudding model viewed the atom as a massive blob of positive charge dotted with negative charges. A plum pudding was a Christmas cake studded with raisins ("plums"). So think of the model as a spherical Christmas cake. When Rutherford shot …
