NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT
Why do amines exhibit high solubility in water? Explain why the solubility of oxygen is lower in water. Does a strong electrolyte dissolve in water to give ions, molecules, or both? Explain. Why kind of molecule is water and what are its characteristics? Give an atomic-level re...
Vegans, however, are not as lenient in consuming cheeses and other animal based products. Do Plants Have Feelings? They have a quest to “never hurt a living thing,” all the while forgetting that plants have feelings too. They have also conveniently forgotten that nature shows us a ...
or programmed cell death.Loss of apoptosisrefers to the “immortality” typical of cancer cells. Normal body cells are programmed to die off when appropriate.130Cancer cells have lost this ability (often as a result of DNA damage), which allows them to reproduce essentially without ...
The fumes of cooking oils contain polycyclic aromatic hydrocarbons (PAHs), heterocyclic aromatic amines, benzene, and formaldehyde, which cause oxidative damages. These toxic particles irritate respiratory membranes, cause coughing and throat burning, increase the risks of respiratory infections, are carcino...
Lewis Structure: The valence electrons in an atom are depicted as dots in Lewis structures, visual representations of molecules. Because it aids in forecasting the quantity and nature of bonds that can be formed around an atom, the Lewis dot struc...
As it seems amazing to have receptors with extremely low affinity for biogenic amines, in the micro to ten millimolar range, one can question the pairing of these molecules with these receptors. Indeed, while one might think that the affinity for its cognate receptor of a blood-borne ...
hydrogen peroxide, copper-containing amine oxidases catalyze the oxidative deamination of primary amines to aldehydes, releasing hydrogen peroxide and ammonia, and tyrosinase oxidizes biological phenols, such as tyrosine and dopamine, participating in this way to the formation of melanin pigments [4,5]...
amines, nitrites, N‑ and O‑heterocyclic hydrocarbons, pesticides, and alkali nitrates have been detected.[30] Toxic metals including mercury, lead, chromium, and other trace elements and several free amino are also present.[31] Nicotine, the addictive substance, exists in two forms, acid...
Beryllium and aluminimum exhibit many properties which are similar . But, the two elements differ in AForming covalent halides BForming polymeric hydrides CExhibiting maximum covalency in compounds DExhibiting amphoteric nature in their oxidesSubmit ...
