Color blindness, also known as color vision deficiency, is the inability to distinguish certain colors in the visible light spectrum. It affects around 8% of men and 0.5% of women, with the most common type being red-green color blindness.
Color blindness can be caused by genetic factors or acquired through injury or disease.
Symptoms include difficulty distinguishing between colors, difficulty identifying colors, and difficulty seeing color in low light or bright light.
Treatment for color blindness is not available, but people with the disorder can often find ways to adapt, such as using color-coded objects or specialized lenses.

Reproduction in Animals: Question and Answers CBSE/NCERT For  Class 8th Chapter 9

Define test-tube baby?
Ans: In-vitro fertilisation, or IVF, is a method used by women who have blocked oviducts and are unable to conceive naturally to create a test-tube baby. For IVF (in vitro fertilisation), doctors take freshly released eggs and sperm and keep them combined for a few hours (fertilisation outside the body). The zygote is given a week to develop if fertilisation occurs before being inserted into the mother’s uterus. Like any other infant, the baby grows completely inside the uterus before being born. Test-tube babies are those born in this manner. This is a misleading term because babies cannot develop in test tubes.
