Cones are concentrated at the center of retina called fovea centralis where no rod cells are present.

The retina is the innermost lining of the eye, made up of thousands of light-sensitive cells, with an inner part of nerve tissue and a pigmented outer part. It plays a fundamental role in the formation of images, which will be projected and then sent to the brain, through electrical impulses.

The retina consists of three types of layers: bipolar neurons, ganglion neurons and photosensitive cells.

Bipolar neurons promote the union of photosensitive cells with ganglion neurons, which are grouped with nerve fibers and thus originate the optic nerve. It carries nerve impulses to the brain. Photosensitive cells, due to their shape, are named in two types: cones and rods.

There are about 6 million cones that are concentrated in a small depression located in the macula lutea (center of the retina) called the fovea. They have an elongated and cylindrical shape, with conical outer segments. It is in this region that the image is most clearly formed, as they are stimulated by the most intense light. Cones are specialized in the accuracy of daytime vision and in recognizing color. There are three types of cones that have fundamental photopigments that respond to light of wavelengths (λ): cyanopigment - S cones (short λ) - sensitive to blue color, chloropigment - M cones (medium λ) - sensitive to green color and erytopigment - cones L (λ long) - sensitive to red color. The brain interprets the signals received by these cones, which allows it to process color differentiation.

What makes argentina culture different to the south america culture?
Anvisha [2.4K]

Answer:

Argentine culture is different from south american culture because it has many more european immigrants than other countries. This is because argentina has many more european immigrants than other countries. This is partially due to the fact that many nazis came here to escape prosection. But other than that they have a lot of italian and spanish immigrants as well.

Which statement about an opinion is false?
pickupchik [31]
Actually, I would argue that to some extend all of them are true:

An opinion is a personal view or attitude.
-this is definitely true, it's basically a definition of an opinion

An opinion is often indicated by the use of adjectives.
-this is true! for example "my teacher is nice"

An opinion is often used as evidence in a news article.
-this is the weakest statement (but I think that it's still not false). I would however choose this as the right answer: opinion is not an evidence for anything except this opinion ( so it's valid for example for the news of "the president thinks that" if the opinion is that of the president.

An opinion has the potential to promote bias. - this is true!

explain why some african amerian were loyalists while others were patriots during the american revolution
krek1111 [17]
One reason that some african americans were patriots was because a few of the high people during that time were racist. (This does not just go to african americans. White people were also patriots) 
One reason that some african americans were loyalists was because some of the people that were in high power were actually african americans. These high powered african americans were not interfered with, due to there were many other people that bad guys wanted to turn into patriots. (DURING THIS TIME, very few african americans were in high power)

I hope that this helped! Please! Please! Please do not feel offended! I was only answering your question! And I caps locked "during this time" because this racist situation was only a big problem during the american revolution.
