Amembrane protein that spans the phospholipid bilayer one or more times is

The right word to fill the blank space is TRANS MEMBRANE PROTEINS.

Explanation:

Membrane proteins are proteins that are found in the cell membranes of living organisms. There are three major types of membrane proteins, these are integral, peripheral and lipid anchored proteins. These proteins perform diverse functions in the transport of materials in and out of the living cells.

The integral proteins refer to those proteins that are permanently anchored to  the cell membranes. Integral proteins are attached to the cells in various ways, some integral proteins are attached to only one side of the membrane and do not span across the whole membranes while some span the whole phospholipid bilayers one or more times.  The integral membrane proteins that span the phospholipid bilayer one or more times are called TRANS MEMBRANE PROTEINS.

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.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
