It is false that constellations are only visible in certain seasons due to the revolution of the Earth toward the constellation.
Answer:
Anatomy supports the theory of evolution because some species share similar physical features that was present in a common ancestor.
An example of shared anatomy is sharks and dolphins. types of analogous structures, such as dolphins and sharks, do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments
Molecular biology because DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
in recent research is has been shown that the myoglobin and hemoglobin sequences for dozens of mammals, birds, reptiles, amphibians, fish, worms, and molluscs were related.
Structural similarities is when different animals share the same structural similarities. For example the skeletons of turtles, horses, humans, birds, and bats are very similar, despite their t different ways of life and the diversity of their environments.
Explanation:
I believe option B would be the correct choice because, without a catalyst, the reaction will be either too slow or will not happen at all as it would not acquire a fitting activation energy for the reaction.
If you would like to know why the other options are incorrect, please read on:
Option A is incorrect because since proteins are specific in nature, so other protein cannot be replaced, for some other chemical reaction.
Option C is not correct it is a genetic defect that the protein does not form, and all cells are genetically identical, a reaction cannot take place in any parts of the body.
And finally, option D would be wrong because if a forward reaction does not take place, a backwards reaction will not occur.
I hope this answer has helped, and I apologise if somehow this answer finds itself to be incorrect. Good luck on your quiz or homework. :)
Answer:
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.
