High risk foods particularly protein foods such as chicken and dairy products are rich in nutrients and moisture and so promote bacterial growth. Time – If provided with the optimum conditions for growth, bacteria can multiply to millions over a small period of time via binary fission .

Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.

Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell.

How to Find Your Blind Spot

1. Close your left eye.
2. Stare at the circle.
3. Move closer to the screen, then farther away.
4. Keep doing this until the plus sign disappears.
5. When it disappears, you found your right eye’s blind spot.

Some blind spots can be caused by migraine, while others can be caused by more serious conditions, such as glaucoma, macular degeneration, or retinal detachment.

The blind spot is located about 12–15° temporally and 1.5° below the horizontal and is roughly 7.5° high and 5.5° wide.

With both eyes open, the blind spots are not perceived because the visual fields of the two eyes overlap. Indeed, even with one eye closed, the blind spot can be difficult to detect subjectively because of the ability of the brain to “fill in” or ignore the missing portion of the image.

If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet. 20/20 vision only indicates the sharpness or clarity of vision at a distance.

A scotoma is a blind spot in your vision. It can be temporary or permanent, and it may stay in the same place or move around in your vision. The spot may be in the center, or it may be around the edges of your vision.
