Speciation is one of the driving processes of evolution and results in the formation of new species.
<h3>What is evolution?</h3>
Evolution is the process by which new organisms are formed from existing organisms due to changes that result in increasing complexity of the organisms.
Speciation is the process by which new species are formed from existing species.
Therefore, it can be concluded that speciation is one of the driving processes of evolution.

Answer:
G-banding or Giemsa banding is a technique used to study the chromosomes by staining then at condensed stage. The visible karyotype can be used by this technique. The genetic diseases can be easily identified by this G banding technique.
The base composition of the genes (nucleotide) are stained by the dye known as Giemsa stain. The nitrogenous base adenine and thymine of the heterochromatic region of chromosome stained darkly in this technique. The darkly stained area is generally gene poor area.
Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
Answer:
Answer is B. Carefully select the food s rich in nutrients but low in calories.
Explanation:
Myplate is a kind of chart showing the amount of food to put in plate in order to stay healthy.
In Margaret situation, the best thing for her is to start selecting food items that are low in calories, and at the same time rich in nutrients. Because if she does not put the nutrients level in consideration, her health will be severely affected.
Some of the examples of foods that are low in calories and rich in nutrients are fish, egg, oats,cabbage, popcorns, brocolli and fruits like apple and berries.
