A researcher is planning an experiment to engineer a nonfunctional version of an RTK. Which engineered protein will most likely be a nonfunctional RTK? an RTK protein with a second enzyme region in the cytosolic portion of the protein,

an RTK protein that can phosphorylate itself even in the absence of the signaling molecule,
an RTK protein that is unable to bind to the signaling molecule,
an RTK protein that has multiple phosphorylation sites

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

b. read the phase at the intersection of any given temperature and pressure.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
