Motor proteins provide for molecular transport of materials in cells by interacting with CYTOSKELETAL STRUCTURES.
Cytoskeletal structures refers to those structures in the cells that provide basis for movement from one part of the cell to another.
Motor protein work together with cytoskeletal structures to carry different type of materials from one point of the cell to another point.

The extra X chromosome is received from mother.
<h3><u>Explanation</u>:</h3>
Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.
Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind. 
 
        
             
        
        
        
A.chromosomes aligning themselves at the equator. 
<h3>What distinguishing features of mitosis' metaphase?</h3>
A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.
<h3>What distinguishes metaphase from other phases?</h3>
Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.
