Which part of the eye helps the eye to focus on objects at different distances?

Explanation:

The Lens (also called the Crystalline Lens) is the adjustable focusing element of the eye. It is located just behind the iris. This process of adjusting the focus for different distances by changing the shape of the lens is called accommodation.

It is the second part of the eye which is basically after the cornea. It's called the retina.

It lets us focus on objects and light 25% to 35%.

Hope this helps

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
