The nature of the indicated covalent bond is polar.

Explanation:

The given diagram is the Lewis structure of Methylamine which has the formula, CH₃NH₂.

In order to know that it is polar, we will discover that in the Lewis structure there are unpaired electrons in the central atom. Also, the bond that exists between the hydrogen and nitrogen shows that it is polar.

CH₃NH₂ is seen to have two charged ends that are opposite and the bonds that exists between hydrogen and nitrogen, which makes it a polar molecule.

The electronegativities of carbon, hydrogen and nitrogen can also be used to determine its polarity.

explanation:

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
