(3) increased fatigue is your answer.
Answer:they possess notochord,dorsal tubular nerve cord , pharyngeal pouches
Explanation:chordates are animals which possess the notochord.examples are humans,birds,fishes etc
At a time in the life cycle,a chordates possesses a stiff,dorsal rod which is supporting in nature (the notochord).
They also possesses a tail that extends from behind the anus.
They possess a hollow nerve cord.
They possess gills slit.
These characteristics are present developing embryo and may disappear as the embryo matures.
In humans,the notochord is replaced by the spinal column of the vertebrate.
Answer:
The solution of P. aeruginosa will yield higher Tm value.
Explanation:
The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.
As P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.
