On the basis of gram reaction only can you distinguish between staphylococcus and streptococcus?
If the Gram stain is properly done, and based on color alone: - you CANNOT distinguish between Staphylococcus (positive/purple) and Streptococcus (positive/purple) - you CAN distinguish between Staphylococcus (positive/purple) and Neisseria (negative/red) - you CANNOT distinguish between Escherichia (negative/red) and Proteus (negative/red) - you CAN distinguish between Escherichia (negative/red) and Bacillus (positive/purple) Gram positives will stain purple because of the retention of the dye (crystal violet) in their thick peptidoglycan cell walls. On the other hand, Gram negatives have a thin cell wall and cannot retain the purple stain, so when they are counterstained, they will appear red
Do cats see black and white or colour?
No, they are not color blind. They see some colors, but not all colors. Cats seem to be able to distinguish between higher frequency colors, meaning cats respond to the colors purple, blue, green and possibly yellow range. Red, orange and brown colors appear to fall outside cats color range and are most likely seen as shades of grey or purple. Purple, blue and green appear to be the strongest colors perceived by cats. Tests suggest cats can distinguish between more shades or levels of gray than can humans. Color is of little importance to cats. Their prey is any color of bird, fish, etc. So they hunt by the motion of their prey, not by its color.
Can cats see colors and what colors can they see?
Cats can indeed see some colors, but not all colors. Research has found that cats have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do.

Can domestic house cats see in color?
Yes, all domestic cats can see in limited color. Research has found that cats have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do.

What color do cats see?
We believe cats do see in color, although not exactly the way we do. In past tests, cats appeared to distinguish between the low to mid light wave spectrum (higher frequency), meaning cats responded to the colors purple, blue, green and yellow range. Red, orange and brown colors appear to fall outside cats color range and are most likely seen as shades of gray or purple. Cats appear to see less saturation in colors than do humans, meaning cats do not see colors as intensely or vibrantly. Blue and green appear to be the strongest colors perceived by cats. Tests suggest cats can distinguish between more shades or levels of gray than can humans.Cats, like dogs, can see some colours: They can tell the difference between red, blue and yellow, and between red and green, although these are less distinguishable. Cats are able to distinguish between blues and violets better than between colours near the red end of the spectrum.Colour is of little importance to cats. They hunt by the motion of their prey, not by its colour.
Do cats hate the color red?
