I believe the correct answer is C. Nektons include bony fish and squid.
Answer:
B
Explanation:
Building more parks and houses will take away homes for animals living there.
<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.
They produce narrow-band high-frequency sound to help them navigate in water. These high-frequency sounds are used in echolocation. Echolocation is used to identify and locate prey and also avoid the predators. Marine mammals like whales and dolphin use echolocation in different manners.
