In a motility assay, investigators attach myosin motor proteins to a glass slide and then add actin filaments. once the filaments have bound to myosin, what can be expected to occur?

 The correct answer is :  In the presence of ATP, the filaments will glide toward their minus ends

Explanation:  During muscle contraction, the myosin and actin filaments do not change in length. Actin filaments are important because they perform several major functions in some types of cells including muscle contraction.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
