7-8 layers

Heterogeneous systems can have varying numbers of layers depending on the specific context, such as in computing, material science, or geology. For instance, in a heterogeneous neural network, there can be multiple layers, including input, hidden, and output layers. In material science, a heterogeneous material may consist of several distinct layers with different properties. Therefore, the number of layers is not fixed and can differ widely based on the application.
there are 3 layers to the animal and human eye: 1. External, which includes cornea and sclera 2. Intermediate, which has two parts a. Anterior, includes iris and ciliary body b. Posterior, includes choroid 3. Internal, which is the retina. Some nocturnal animals like cats for instance have a layer in the back of the eye that reflects/multiplies light coming into the eye, thus allowing them to see in the dark better. This layer is called the "Tapetum lucidum".
No and many people think the cornea is in the corner of your eye it is located in the center of your eye.
Cows cows cows.
Yes, There are many cows in Africa.
you can have as many cows you can fit on your farm
Well, isn't that just a happy little puzzle! Let's break it down nice and easy. If Fred has 15 cows, and John has twice as many cows as Fred had when Fred had as many cows as John has now, John must have 30 cows. So John has 30 cows in this peaceful little scenario.
Blue cows are in 17.
Many studies were done but besides infections one of the dangers that involve long-term contact lenses wear was that it induces significant changes in all layers of the cornea.
Many types of cows originated in Europe. These cows can just reproduce, but other cows can be imported from all over.
About half as many cows died as pigs.
