Answer: Second option is correct.
Explanation:
Valley and mountain breezes are examples of local winds.
It occurs one by one on a regular cycle.
Valley and mountain breezes is similar to sea and land breezes.
Hence, second option is correct.
Answer:
Water is bolar
Explanation:
One side of the water molecule is slightly positive and the other is slightly negative. Water is made up of two hydrogen and one oxygen atoms. The bond in this arrangement is called a covalent bond. In addition to this, water is also called the universal solvent and is capable of sharing charges with a large amount of ionic compounds when mixed allowing them to be dissolved. In essence the strong bond is reduced. This weakens the ionic and hydrogen bonds in the presence of water. Next, in a vacuum, there are no other electrons to share charges with and the hydrogen and ionic bonds are said to be strong to an immeasurable amount, in some reports, infinity.
A covalent bond I believe.
Answer:
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
Explanation:
From the Punnet's square analysis (see the attached image);
- <em>A_B_ 9/16 </em>
- <em>A_bb 3/16</em>
- <em>aaB_ 3/16</em>
- <em>aabb 1/16</em>
A_B_ and A_bb will always give offsprings with bright white fur since allele A always mask the effect of B.
aaB_ will always give offsprings with black fur since allele a does not produce any protein.
aabb will give offsprings with brown fur since b codes for brown fur colour.
Hence, the phenotypic ratio of the offspring will be;
<em>Bright white fur 3/4</em>
<em>Black fur 3/16</em>
<em>brown fur 1/16</em>
