X = about 1 or x = about -2
9x^2 + 12x - 24 is standard form: ax^2 + bx + c
quadratic formula: x = (-b ± <span>√(b^2 - 4ac)) / 2a
x = -12 </span>± <span>√(12^2 - 4(9)(-24)) / 2(9)
</span>x = -12 ± <span>√(144 - (-864) / 18
</span>x = -12 ± <span>√(144 + 864) / 18
</span>x = -12 ± <span>√(1008) / 18
</span>x = -12 ± √(1008) / 18
x = −2 ± 2√7/3
x = -2 + 2√7/3 or x = -2 - 2√7/3
x = 1.0971675407097272 or x = −<span>2.4305008740430605</span>
Answer:B
Explanation:
Agonist-induced desensitization involves phosphorylation of G protein-coupled receptors by two currently recognized classes of serine/threonine protein kinases. Second messenger-dependent kinases, phosphorylating a variety of proteins, mediate a generalized cellular hyporesponsiveness termed heterologous desensitization. G protein-coupled receptor kinases (GRKs) phosphorylate specifically agonist-occupied, or activated, receptors, and thereby initiate receptor-specific, or homologous, desensitization.
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion
