What is the blind spot of the eye?
explain it.

Answers

Answer 1
Answer: A blind spot, scotoma, is an obscuration of the visual field. A particular blind spot known as the blind spot, physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc. Since there are no cells to detect light on the optic disc, a part of the field of vision is not perceived. The brain interpolates the blind spot based on surrounding detail and information from the other eye, so the blind spot is not normally perceived.
Although all vertebrates have this blind spot, cephalopod eyes, which are only superficially similar, do not. In them, the optic nerve approaches the receptors from behind, so it does not create a break in the retina.

Which statements describe color and streak? Check all that apply. - streak is the color of a minerals powder.
- most minerals occur in more than one color
- color is more accurate than streak in identifying minerals
- steak is tested by scraping a mineral across a streak plate
- the color of the streak is the same as the color of the mineral

Answers

Answer:

A mineral is an inorganic substance that is extracted from the ore after the mining process. The mineral can be identified on the basis of physical properties like color, luster, appearance, texture and by the chemical composition.

The streak is the method of mineral identification in which the mineral is scrapped off across a streak plate to determine the exact color of the mineral by the color of the powder as two or more minerals may look alike on the basis of color. This method will allow to determine the exact color of the mineral.

On the basis of the above description, these are correct statements:

- streak is the color of a minerals powder.

- most minerals occur in more than one color.

- steak is tested by scraping a mineral across a streak plate.
