What is an isotope? What is meant by isotopic stability? Are the chemical properties of different isotopes of the same element the same? Do all elements have at least several isotopes?What happens in the nuclear equation of beta decay? a. the new nucleus contains 2 fewer protons b. the ...
What is the concept of equilibrium in biology? a) How does synchrotron accelerates work? b) Describe what might happen to the particles in the acceleration if the magnetic field was too weak? Explain the difference between an isotope and an ion. ...
isotope isobar isochronous isogloss isomer isometric isotherm isomorphic Life is not easy for any of us. We must work, and above all, we must believe in ourselves. We must believe that each of us is able to do something well, and when we discover what this something is, we must work ha...
The typical interpretation of what is meant by an "extra" toe is that the bird exhibits the anisodactyl condition: the hallux points posteriorly, while digits II–IV point anteri- orly (Fig. 7a). The anisodactyl condition gives the birds with this trait an opposable hallux useful for ...
(Side note: this is why I’ve always rejected the notion of Paleo as an “all-meat” diet; a more accurate descriptor would be a plant-based diet that also contains animal products). When we consider the importance of both essential and nonessential nutrients, it also becomes clear that ...
However, with targeted agents functional imaging changes are likely to be apparent at lower doses than the MTD because of biological activity of the agent by direct target inhibition. A plateau level at which increasing dose is not followed by an imaging parameter change suggests that imaging may...
The “extra toe” is not in fact extra: it is simply pedal digit I, the hallux, more familiar to us as the big toe of humans or the dewclaw of the hind foot of some dogs. The typical interpretation of what is meant by an “extra” toe is that the bird exhibits the anisodactyl ...
An element is defined by the number of protons in its nucleus, so this process transforms iron into heavier elements, like gold, in what is almost a form of cosmic alchemy. It is theradiation from the decay of the radioactive elementscreated during the r-process that makes the material eje...
When hydrated, magnesium sulfate becomes magnesium sulfate heptahydarate. The chemical compound is represented as MgSO4(H2O)7. The magnesium sulfate molecule is the MgSO4 portion of the symbol of Epsom salts, and the (H20)7 is meant to show that the magnesium sulfate molecule is bound to sev...
My textbook states that: "Resistance of a given conductor is due to the collisions of free electrons with the ions or atoms of the conductor while drifting towards the positive end of the conductor." What is meant by "collision" here? If we think deeply, can the free electrons actually "...
