Answer;
-The third stage fever
Explanation;
-Fever, also referred to as pyrexia and febrile response, involves having a temperature above the normal range (above 37.5 or 38.3 °C) due to an increase in the body's temperature set-point (36.5–37.5 °C). This increase in set-point temperature triggers increased muscle contractions and causes a feeling of cold.
-The first stage of a fever is marked by headache and body aches, the second stage is marked by the chills, and the third stage is the flush state. The fourth stage is defervescence.
Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
Your answer is C.) The hydrogen bond between complementary nucleotides
Those rectangles are nucleotides, and the nucleotides are held together by hydrogen bonds.
Hope this helps!
