Why do you think<br> organisms in the<br> same kingdom are<br> not all identical?
vodomira [7]

Answer:

Evolution, mutation, and adaptation

Explanation:

Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.

I am trying to determine reactants going into the electron transport chain. Is this right?
irina1246 [14]

Answer:

Yes, this is correct.

Explanation:

  • In each glycolytic pathway, glyceraldehyde 3-phosphate dehydrogenase produces 1 molecules of NADH as a result of reduction of NAD+.
  • Pyruvate dehydrogenase converts pyruvate to Acetyl CoA producing 1 molecule of NADH per pyruvate oxidized.
  • In Kreb's cycle, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and malate dehydrogenase reactions produce 1 molecule of NADH each. Furthermore, succinate dehydrogenase reaction produces a single molecule of FADH2 per FAD reduced.
  • Since, we began with 2 molecules of glyceraldehyde 3-phosphate, we  multiply the above figures by 2 and get a total of 10 NADH and 2 FADH2.

Which two globin genes are most divergent from each other? what is the percent amino acid identity between them?
tiny-mole [99]

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.
