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.
Answer: I think it's A: the DNA of all organisms contains the same four bases.
1. <span>D. Molten material beneath Earth's crust rises to the surface.
2. </span><span>A. The mid-ocean ridges
(This is asking for what form. The Andes is a mountain range in Peru)
3. </span><span>C. Subduction causes the ocean floor to sink into deep ocean trenches.
(Subduction is when part of the ocean floor sinks under a deep-ocean trench and return the the mantle; this is caused by the movement of tectonic plates)

Answer:
causing degradation of transcription factors and changing which genes are expressed
Explanation:
Ubiquitination (addition of ubiquitin to a protein) is the first step in protein degradation process, and it directs protein to the proteasome for degradation. This process involves three steps with specific groups of enzymes to perform them, which are activation with ubiquitin-activating enzymes, conjugation with ubiquitin-conjugating enzymes and ligation with ubiquitin ligases. These enzymes would be most likely to regulate gene expression by causing degradation of transcription factors and changing which genes are expressed.
