Normal colour vision (trichromacy) refers to vision that uses all three types of light cones. People with defected trichromatic vision will be colour blind to some extent and these conditions are called anomalous trichromacy. Three types anomalous trichromacy ( one type of cone perceives light slightly) :
1. Protanomaly – phenotype: reduced sensitivity to red light
2. Deuteranomaly - phenotype: reduced sensitivity to green light
3. Tritanomaly – phenotype: reduced sensitivity to blue
People can also have color blindess as the result of mutation, when loss of function of one cone occurs. This condition is called dichromacy. If there is complete color blindness or monochromacy, the person can’t distinguish any color from grey.
Color blindness is an inherited genetic disorder resulted from mutations on the X chromosome.
Answer: Positive
Explanation:Because of the gain in speed
The correct sequence is sources emit greenhouse gases; global temperatures rise; snow and ice melt; and sea levels rise. The natural and man made sources emit greenhouse gases that are responsible for the greenhouse effect. The increase in the Earth's temperature due to these gases absorbing more heat from the sun caused climate change like melting of snow and ice which contributes to the rising sea levels.
