When  sodium chloride  is formed  from a positively charged sodium atom and a  negatively  charged  chlorine  atom,  the charge  on the salt becomes  neutral   is true
  Explanation
 Sodium  ion ( positively  charged)  combine with chloride  ion ( negatively charged)  to  sodium chloride which  is neural  according  to equation below.
 Na⁺   +  Cl⁻    →  NaCl  (<em>neutral</em>) 
Equal  number  of positive  and negative  charges  add up to make neutral  Nacl therefore the statement above is true.

The allele for dwarfism - D its dominant 
Recessive allele -d
If the person has heterozygous alleles -Dd the person will have achrondroplastic dwarfism
However if the person if homozygous for the allele DD it’s Lethal and person can’t survive
If both parents are Dd 
 Dd X. Dd
Offspring DD Dd Dd dd 
Probability of children who survive with the trait have the genotype Dd 
Probability - 1/4 + 1/4 
 Probability of having surviving children with the trait -1/2 -0.5
        
             
        
        
        
Answer:
The power of the lens of an eye adjust or bends the light rays to provide an image on the retina depending on distance of the object.
Explanation:
 The lens of an eye and the cornea work together in forming a real image in the retina that houses numerous receptors in the fovea and blind spot of the optic nerve.
Image will be formed  in the retina when light rays converging most at the cornea upon entering and exiting the lens.The power of adjusting the eyes focal length is known as accommodation.
