Answer:
The female (XcX) is carrier for color blindness while the male (XY) is normal. The carrier female transmits its one X chromosome with gene for color blindness to one of her sons making him color blind.
Explanation:
Color blindness is X linked recessive disorder and followed the criss-cross inheritance wherein the color blind sons get the gene from their carrier/affected mother while the color blind father would transmit the gene to his daughters along with X chromosome.
Since both the parents are normal, the mother (XcX) should be carrier for the disease to get the color blind son. A cross between carrier mother (XcX) and normal father (XY) would make 50% of their sons color blind.

Language degradation is occurring because of the adoption of foreign languages.
<h3>How does this adoption take place?</h3>
The constant presence of foreign media and the adoption of foreign language terms is the main way to adopt a new language.
This adoption allows the local population to start mixing the two languages.
Over time this process becomes more intense, causing the local language to be replaced by a foreign language over time.
Language degradation is a process that occurs in many regions, but maintaining these languages is very important.
