Now-a-days cornea transplantation is very popular. The reason is that it:
1 Cornea is easy to preserve
2 transplanted very easily
3 can be easily obtained
4 Cornea does not link with blood supply and immune system
Explanation:
D Cornea is the only human part where there is no blood supply cornea can absorb oxygen directly from the air. So that cornea transplantation is more successful. The transplantation of cornea called keratoplasty.

A person is wearing spectacles with concave lenses for correcting vision. While not using the glasses, the image of a distant object in his case will be formed
1 on the blind spot
2 behind the retina
3 in front of the retina
4 on the yellow spot
Explanation:
C The person wearing spectacles with concave lenses for correcting vision suffers from myopia (near sightedness). In this case the object image will focus before the retina. It is due to eye ball become large or eye lens become thick when lens become thick focus distances decreases. A concave lens is also called a diverging or negative lens.

Which part of the human eye adjusts the focal length of lens?
1 Cornea
2 Aquous humour
3 Conjunctiva
4 Ciliary body Rajasthan
Explanation:
D The ciliary body is a circular structure that is an extension of the iris, the colored part of the eye. - The relaxation or contraction of cilliary muscles changes the curvature of the eye lens. The change in curvature of the eye lens change the focal length of the eyes. Hence, change in focal length of an eye lens is caused by the action of cilliary muscles.

Which of the following pair is monosaccharide?
1 Glucose and sucrose
2 Ribose and maltose
3 Fructose and glucose
4 Ribose and sucrose
Explanation:
C Monosaccharide's are the simplest form of carbohydrate. They consist of one sugar and are usually colorless, water soluble and no need digestion glucose, galactose and fructose are monosaccharide and share the same molecular formula \(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\). However the arrangement atoms is different is each of these three sugars.

Too short eye ball and too flat lens produce :
1 Near sightedness
2 Far sightedness
3 Astigmatism
4 Presbyopia
Explanation:
B Farsightedness or Hypermetropia is caused when the eyeball of a person is too short or the lens of the eyes is too flat. In such cases the eyes are not able to focus the incoming light on the retina wall instead focus it behind it due to insufficient accommodation by the lens.
