Because of the property of paleomagnetism, iron rich rocks show the location of magnetic poles at the time of their formation.
Paleomagnetism is concerned with the study of materials that have a record of the earth's magnetic field due to the content of magnetizable material within them. As iron is easily magnetized, materials with a high iron content are likely to indicate the nature of the magnetic field of the earth when they are formed.
Answer:
kinetic energy
Explanation:
kinetic is when something is moving and potential is when an object isn't moving, but has the potential of having an increase in energy :)
Oxygen molecules are too small and glucose molecules are quite large than oxygen. So they can't passively disuse inside a cell.
Option C
<h3><u>Explanation:</u></h3>
Glucose molecules are large molecules with a molecular formula of C₆H₁₂O₆ These molecules need special protein channels or transporters called Glucose Transporters or GLUT to make them way through the cell membranes. While smaller molecules like oxygen, carbon dioxide, smaller polar molecules like <em>water</em> or even fat soluble molecules like chloroform and benzene do pass through the membranes easily by means of passive diffusion.
The oxygen molecules are needed inside a human cell for aerobic respiration and glucose molecules are needed because of a respiratory substrate. So Glucose needs receptors and transporters to pass through the membranes.
