this is because they swim in water.Their streamline body makes them ideal to swim underwater.Penguins cannot fly in air but it can be said they fly through water
The amniotic fluid helps keep the temperature of the prenatal world constant.
Amniotic fluid surrounds the developing fetus inside the womb and protects the fetus from injury and temperature changes. It additionally lets in for freedom of fetal movement and permits musculoskeletal improvement.
Amniotic fluid is chargeable for: defending the fetus: The fluid cushions the infant from outdoor pressures, acting as a shock absorber. Temperature manipulation: The fluid insulates the child, maintaining it warm and preserving a normal temperature. contamination control: The amniotic fluid carries antibodies.
In the beginning, amniotic fluid is especially water with electrolytes, however, using approximately the 12-14th week the liquid also incorporates proteins, carbohydrates, lipids and phospholipids, and urea, all of which aid in the growth of the fetus.

<h2>Next generation
DNA sequencing</h2>
Explanation:
CDC must use Next generation DNA sequencing method to determine the DNA sequence of the dengue virus.
The mostly used sequencing methods now a days are called Next-generation sequencing methods. They are faster, cheaper , accurate and need a small amount of sample.
Next generation sequencing platforms perform massively parallel sequencing, during which millions of fragments of DNA from a single sample are sequenced in unison. Massively parallel sequencing technologies facilitates high -throughput sequencing, which allows an entire genome to be sequenced in one day.
in Medical research where speed is necessary and sample size is small, these sequencing technology will be best to be used.
I believe it is either B or A, personally i'm leaning towards B, but at the same time, i don't think that we would be obtaining materials via pollination, so it then causes A to make more sense.
