Answer:

Option D

Explanation:

Given -

Duchenne muscular dystrophy is an X-linked recessive disorder.

The mother is heterozygous recessive for the Duchenne muscular dystrophy.

In this case if X' represent the affected allele, the genotype of affected female would be  XX'

Also, the father is unaffected but is the carrier of recessive affected allele. Hence, Genotype of father would be X'Y

Cross between XX' and X'Y would give the following offspring -

XX', XY, X'X', X'Y

All the female offspring will have recessive allele for Duchenne muscular dystrophy disorder

Hence, the probability of a female offspring with recessive allele for Duchenne muscular dystrophy disorder will be 100 percent

Hence, option D is correct

AlekseyPX

The right answer is Filtration.

A water filter is composed of a filtration system that aims to separate the water from the solid particles (residues) by passing it through a porous medium, which allows only the liquids and the finer solid particles to pass through. as the filter holes (porosity). The water that comes out of this filtration system is rid of solid particles larger than the pores of the filter.

Some water filters are designed to make drinking water (very fine filtration, less than the size of a microbe).
