[EX Q]: A quantity analogous to this effect in electrodynamics is called the Christofel voltage, while large motions restored by it were found by Carl Rossby. The Etvs effect accounts for its vertical component, and Buys-Ballot's Law is a result of this effect in areas of different pressure. Present only in non-inertial frames of reference, this effect was also considered when Laplace derived his tidal equations, and it influences the rotation of sunspots and the circulation of the atmosphere. Proportional to the cross product of the angular frequency and velocity, this is, FTP, which force that describes the tendency of a body to drift away from its course due to the Earth's rotation

[EX Q]: One protein that binds to this protein also binds to proline-rich sequences in the membrane proteins Vasp and Mena, and another is knocked out in the singed mutant. Phosphatidyl-inositol-4,5-bisphosphate regulates the binding of vinculin to both talin and this other protein, whose function is performed by nematode Major Sperm Protein in the only (*) eukaryotic cells known to lack one form of it. In addition to the aforementioned profilin and facsin, severin and gelsolin bind to this protein and sever it. Two toxins often used to study it are cytochalasins and phalloidin. Thymosin 4 sequesters this protein, which undergoes treadmilling because the critical concentration at its (+) and (-) ends is not the same. This protein consists of G monomers which polymerize into F filaments, which make up the microfilaments of the cytoskeleton. For 10 points, name this protein that forms cross-bridges with myosin in muscle cells.
