Answer:
<h2>C. To date rock layers</h2>
Explanation:
<em>They can help determine the relative age of rock layers</em>.
Explanation:
As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.
Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

The procedure of dialysis maintains the body in balance by withdrawing waste, extra water, and salt by preventing them from accumulating up in the body when the kidneys fail. It helps in maintaining a safe level of some kinds of chemicals in the blood, like sodium, potassium, and bicarbonate. It helps in monitoring blood pressure.
Hence, dialysis helps in performing a function for the circulatory system of the body.
Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol, SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses, SRP binds to its receptor, Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
Answer:
Enzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed. In nature, exergonic reactions do not require energy beyond activation energy to proceed, and they release energy.
