What purpose does a fish ladder serve?
Whitepunk [10]

<u>Answer</u>: Option A

<u>Explanation</u> :

  • A<em> fish ladder</em> is also known as fish steps, fish pass or fishway.
  • It is built around waterfalls, dams and locks.
  • The purpose of building a fish ladder is to<em> facilitate the natural migration of diadromous fishes.</em>
  • A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.
  • Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.

How do the three types of colorblindness differ in genotype and phenotype?
vfiekz [6]

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.
