guapka [62]

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

  • In water molecules hydrogen bonds provides a special dipole - dipole attraction.
  • Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
  • This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
  • This makes the molecule of water polar.
  • By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.

Serga [27]

Answer:

The correct answer is dominant.

Explanation:

On the basis of the given question, both the parents are suffering from piebald spotting, that is, a condition in which patches of the skin is devoid of pigmentation. It is given that one of the progenies of the parents is exhibiting normal skin, while other is exhibiting piebald spotting.  

The condition results due to the non-tendency of the cells that generate pigment to migrate appropriately at the time of development indicate that if the trait would have been recessive, then both the child should have been suffering from the condition. As this is not the case, it shows that the trait is dominant, and it also shows that the two parents are heterozygous for the trait not homozygous.
