Explanation / Answer

Ans 6: I could taste sweet (or salty) on more than one part of the tongue tested - receptors must be located at least in these areas of the tongue.

Since the tongue tested the taste in more than one part, the receptors indeed are located at least in these parts. As such the tip of the tongue has taste buds that are sensitive to sweet taste and laterally that are sensitive to sour taste.

Ans 9: Photoreceptor

Photos = light.

Ans 10: black.

Rods respond only to difference sin light intensity and thus can respond well to black, white and shades of grey.

Ans 11: True.

Anatomically, the eye does have a region where they aren't any photoreceptors and this corresponds to the position of optic disk.
