If light strikes one receptor, the net effect is to ________ the nearest bipolar cell and ________ other bipolar cells to the si
mrs_skeptik [129]

If light strikes one receptor, the net effect is to excite the nearest bipolar cell and inhibit other bipolar cells to the side because of the contributions from horizontal cells.

<u>Explanation:</u>

On striking the receptor with light, the nearest bipolar cells respond to the light at the most inside the circumference. The bipolar cells which are outside the circumference responds least to the phenomena. Overall, the net effect thereby when seen, is to excite the nearest bipolar cells.

By the excitement of nearest bipolar cells, other farther cells are inhibited as a result as the horizontal cells are also excited and they contribute to inhibit the bipolar cells which are not near to the receptor cells in the eyes.

Mnenie [13.5K]

Hallo~~

Your question is related to genetics.

Have you ever done a Punnett Square? This question forces you to make one. If your cross a homozygous type A (AA) and homozygous type O (OO) you should get 100% AO. Understanding genetics, an AO gene means a type A blood. Therefore, it's 100% type A blood (AO).

Nuetrik [128]

Answer:

Explanation:

LPG gas is basically propane and butane, and it is odourless in its natural state. The smell that you notice when there is a leak is actually the stench of an entirely different agent, called Ethyl Mercaptan (C2H6S). This substance is added to the gas when it leaves the main storage terminals.
