2. Homothallism - Wikipedia

   en.wikipedia.org/wiki/Homothallism

   Homothallic refers to the possession, within a single organism, of the resources to reproduce sexually; [1] i.e., having male and female reproductive structures on the same thallus. The opposite sexual functions are performed by different cells of a single mycelium. [2] It can be contrasted to heterothallic. It is often used to categorize fungi.

3. Heterothallism - Wikipedia

   en.wikipedia.org/wiki/Heterothallism

   Heterothallic species have sexes that reside in different individuals. The term is applied particularly to distinguish heterothallic fungi , which require two compatible partners to produce sexual spores, from homothallic ones, which are capable of sexual reproduction from a single organism.

6. Chemical physics - Wikipedia

   en.wikipedia.org/wiki/Chemical_physics

   The term "chemical physics" in its modern sense was first used by the German scientist A. Eucken, who published "A Course in Chemical Physics" in 1930. Prior to this, in 1927, the publication "Electronic Chemistry" by V. N. Kondrat'ev, N. N. Semenov, and Iu. B. Khariton hinted at the meaning of "chemical physics" through its title.

7. Chirality - Wikipedia

   en.wikipedia.org/wiki/Chirality

   In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. [4] Not to be confused with helicity , which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin.

9. Chirality (physics) - Wikipedia

   en.wikipedia.org/wiki/Chirality_(physics)

   A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality).The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality.
