<span>The migration routes of Homo sapiens reveal
that they went through many environmental and physical challenges but adapted
everything much quickly in comparison to the other animals. The evolution
allowed other species also to adopt these changes but it took them a long time
to fit in the new environment, a sub species of a species adopted the new and
the previous one could not, but Homo sapiens invented ways and tools to combat
and evolve much quickly. It included their living, dietary needs, clothing and
much more.</span>

Its called pigment chlorophyll
Answer:
64.
Explanation:
It is 64 because there are 20 amino acids with four bases ( A,T,C and G).
and genetic code can be read in triplets and also the four bases can occupy the positions. Eachh amino acid can be coded by the triplet codons. A triplet codon shows three nucleotides of the mRNA template that can code for amino acid
Therefore the number of codons is 4×4×4= 64.
There are choices for this question namely:
<span>
Leukopenia
Weight gain
Polycythemia
Hepatomegaly
Jugular vein distension
The correct answers are "weight gain", "hepatomegaly" and "jugular vein distension". Along with bipedal edema, these signs are associated with the complication of COPD which is called <em>cor pulmonale</em>. Cor pulmonale is a kind of right sided heart failure wherein blood pools to the systemic circulation because the right side of the heart cannot overcome the pulmonary vascular resistance brought about the COPD. Pooling of blood in the systemic circulation causes bipedal edema, hepatomegaly (cardiac cirrhosis; congestion of the liver), weight gain (increased interstitial fluid volume), and jugular vein distension. </span>
