  2. Blending inheritance - Wikipedia

    en.wikipedia.org/wiki/Blending_inheritance

    Blending inheritance is an obsolete theory in biology from the 19th century. The theory is that the progeny inherits any characteristic as the average of the parents' values of that characteristic. As an example of this, a crossing of a red flower variety with a white variety of the same species would yield pink-flowered offspring.

  3. Miscibility - Wikipedia

    en.wikipedia.org/wiki/Miscibility

    Miscibility (/ ˌ m ɪ s ɪ ˈ b ɪ l ɪ t i /) is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution). Such substances are said to be miscible (etymologically equivalent to the common term "mixable").

    RNA folding problem: Is it possible to accurately predict the secondary, tertiary and quaternary structure of a polyribonucleic acid sequence based on its sequence and environment? Protein design : Is it possible to design highly active enzymes de novo for any desired reaction?

  5. Mixing (process engineering) - Wikipedia

    en.wikipedia.org/wiki/Mixing_(process_engineering)

    Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...

  6. Miller–Urey experiment - Wikipedia

    en.wikipedia.org/wiki/Miller–Urey_experiment

    The experiment used methane (CH 4), ammonia (NH 3), hydrogen (H 2), in ratio 2:2:1, and water (H 2 O). Applying an electric arc (simulating lightning) resulted in the production of amino acids. It is regarded as a groundbreaking experiment, and the classic experiment investigating the origin of life (abiogenesis).

  7. Mixing study - Wikipedia

    en.wikipedia.org/wiki/Mixing_study

    If the problem is a simple factor deficiency, mixing the patient plasma 1:1 with plasma that contains 100% of the normal factor level results in a level ≥50% in the mixture (say the patient has an activity of 0%; the average of 100% + 0% = 50%). [3] The PT or PTT will be normal (the mixing study shows correction).

  8. Mixing (mathematics) - Wikipedia

    The process is called ρ-mixing if these coefficients converge to zero as t → ∞, and “ρ-mixing with exponential decay rate” if ρ t < e −δt for some δ > 0. For a stationary Markov process, the coefficients ρ t may either decay at an exponential rate, or be always equal to one. [3] The α-mixing coefficients of the process {x t} are
