Useful traits have been accumulated in plants and animals over the centuries by how plants have undergone through certain phases, specifically called selection. Most of these traits are accumulated naturally but others may be acquired in the opposite way through man-made cultivation. Hope this answers your question.
Tornadoes<span> are often visible as a funnel cloud. Perhaps the only </span>similarity between tornadoes and hurricanes<span> is that they both contain strong rotating winds that can cause damage.
Hope this helps :)

Explanation :
The modern form of calculating any parameter is called the international system of units.
Meter, kilogram, Newton etc are the SI units of length, mass and force respectively. To express any quantity it is required to first convert it into SI units.
The length, breadth, distance and height of an object is measured in meters.
For example, Newton is the SI unit of force. Force is the product of mass and acceleration. The SI unit of mass is Kg while the SI unit of acceleration is 
. So, the Newton is equivalent to 
.
This is called a frameshift mutation....
Losing one nucleotide would cause the entire framework of codons (the 3 nucleotide set that codes for the amino acids) to move off by 1 which results in likely completely different amino acids being called for when the protein is built.
In the case of CF, the normal CFTR gene which codes for Cystic Fibrosis Transmembrane Receptor - a membrane protein, with a point mutation would not be made properly and is therefore not placed into the membrane of the cells of the offspring - this protein is very important in moving sodium into the cell - if this is messed up it results in disease.
Note that CF can result in a number of different types of mutations to the CFTR gene...a frameshift mutation is just one way.
The
correct answer is no.
<span>The
development of retinoblastoma occurs as a consequence of mutation of genes RB1
or MYCN. Those mutations occur in the early stages of fetal development and affect
the way in which cells grow and develop within the body. The more common is the
defective RB1 gene that can be inherited from either parent. The expression of
the RB1 allele is autosomal dominant.</span>
