Asheet-like body that cuts across rock layers and is produced when magma is injected into a fracture is called a

Is called a di-ke.

(The correct writing is without the hyphen, but I had to put it because of the censorship).

Explanation:

Di-ke is a term used in geology to indicate a tubular formation that provides cuts in a rock. In other words, a di-ke is a leaf-shaped body that cuts through rock layers and is produced when magma is injected into a fracture in a rock. The dimensions of a di-ke are variable, may have millimeters and even masters, sometimes heads to reach kilometers, but is rare.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
