Answer:
We mean that a cell changes to another type of cell.
Explanation:
<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally. 
Then, a differentiated cell is a cell that had gone under the previously described process.

Answer:
C. tend to be transmitted together.
Explanation:
Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes. 
 
        
             
        
        
        
Null hypothesis<span> are never accepted. We either </span>reject<span> them or fail to </span>reject<span> them. The distinction between “acceptance” and “failure to </span>reject<span>” is best understood in terms of confidence intervals. Failing to </span>reject<span> a </span>hypothesis means<span> a confidence interval contains a value of “no difference”.
Hope this helps. </span>
