Describe passive transport using the words concentration and concentration gradient
dsp73
Passive transport<span> is a movement of </span>biochemicals<span> and other </span>atomic<span> or </span>molecular<span> substances across </span>cell membranes through <span>concentration gradients</span><span> without need of </span>energy<span> input. Unlike </span>active transport<span>, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in </span>entropy<span>. The rate of passive transport depends on the </span>permeability<span> of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane </span>lipids<span> and </span>proteins<span>. The four main kinds of passive transport are simple </span>diffusion<span>, </span>facilitated diffusion<span>, </span>filtration<span>, and </span>osmosis.

Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. What
Radda [10]
Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles.
So, if father has dominant allele (H), the probability that a <span>female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:
 
                    Father              Mother
Parents:       H             x          Hh
Daughter:     HH or Hh

</span>      Father              Mother
Parents:       H             x          HH
<span>Daughter:     HH
</span>
      Father              Mother
Parents:       H             x          hh
<span>Daughter:     Hh or Hh
</span>
But, if the father has recessive allele, the probability that a <span>female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype.
If mother is dominant homozygous, there will be 0% of possibility:
</span>                       Father              Mother
Parents:             h          x          HH
<span>Daughter:     Hh
</span>
If mother is recessive homozygous, the possibility is 100%:
                    Father              Mother
Parents:           h         x         hh
<span>Daughter:     hh
</span>
If mother is heterozygous, the possibility is 50%:
                   Father              Mother
Parents:          h         x         Hh
<span>Daughter:     Hh or hh</span>
