FAQs on Human Eye Colourful World - MCQ, Science, Class 10
| 1. What is the role of the iris in determining eye color? |  |
Ans. The iris is the part of the eye that determines eye color. It is a muscle that controls the size of the pupil, which regulates the amount of light that enters the eye. The color of the iris is determined by the amount and type of melanin in the front layers of the iris.
| 2. Can two parents with blue eyes have a child with brown eyes? | |
Ans. Yes, it is possible for two parents with blue eyes to have a child with brown eyes. Eye color is determined by multiple genes, and it is possible for recessive genes for brown eyes to be passed down from both parents and express themselves in their child.
| 3. What are some factors that can affect eye color? | |
Ans. Eye color can be affected by several factors, including genetics, age, and disease. Some medications and drugs can also cause changes in eye color, as can exposure to certain chemicals.
| 4. Is it true that people with lighter eye colors are more sensitive to light? | |
Ans. Yes, it is true that people with lighter eye colors tend to be more sensitive to light than those with darker eye colors. This is because darker irises contain more melanin, which helps to absorb more light and protect the eye from glare.
| 5. Can eye color change over time? | |
Ans. Yes, eye color can change over time, especially during childhood and adolescence. This is because the amount and type of melanin in the iris can change as a person ages. Certain diseases and medications can also cause changes in eye color. However, once a person reaches adulthood, their eye color is usually stable and does not change significantly.
