Hi There!
Question:
Which statements indicate what the fossil record suggests about evolution on Earth? Check all that apply.
Answer:
Organisms originally lived only in Earth’s water.
Plants did not have flowers when dinosaurs existed.
Why:
Plants existed when dinosaurs did but they didn't have any flowers, because flowers came along way after plants existed. When earth was form you see that it says earliest waters so that would have meant the first organism brought to earth were organisms that lived in the water.
Hope This Helps :)
Answer:
The correct answer is c) They are used to form ATP by chemiosmosis
Explanation:
In cellular respiration, glucose is oxidized into carbon dioxide and water and converts into NADH a FADH₂ during glycolysis and Kreb cycle. Then these reduced molecules are used to provide the source of electrons during chemiosmosis.
This transfer of electron to electron transport chain brings the conformation change in proteins that helps in transport of H⁺ions across the inner membrane of mitochondria. This transport of ions increase the proton gradient in the membrane.
So to equalize the proton gradient H⁺ moves towards the matrix through ATPase which allows the formation of ATP from ADP. Therefore the right answer is c) They are used to form ATP by chemiosmosis.
The evidence that supports the autogenic hypothesis is that transfer of DNA occurs between bacteria species.
The endosymbiotic hypothesis is that a prokaryotic cell “ate” smaller organelles which evolved into what they are today.
