Direction Q.31 to 35

Animals emit low frequency electric fields due to process known as osmoregulation. This process allows the concentration of ions (charged atoms or molecules) to flow between the inside of our bodies and the outside. In order for our cells to stay intact, the flow of ions needs to be balanced. But balanced doesn't necessarily mean equal. The concentration of ions within a shrimp's body is much lower than that of the sea water it swims in. Their voltage, or potential difference generated between the two concentrations across 'leaky' surfaces, can then be measured.

Read the above passage carefully and give the answer of the following questions..

The Gaussian surface for ions in the body of animals:

A) can pass through a continuous charge distribution

B) cannot pass through a continuous charge distribution

C) can pass through any system of discrete charges

D) can pass through a continuous charge distribution as well as any system of discrete charges
