Answer:
The correct answer is A and D
Explanation:
According to Russell's conception that lies in natural proton gradients. He states that Four billion years ago, alkaline fluids bubbled to produce mildly acidic oceans (As CO2 levels were about a thousand times higher, and it reacts with H2O to form carbonic acid, rendering the oceans mildly acidic). Acidity is just a measure of proton concentration, higher in the oceans than in vent fluids. This difference has given rise to a natural proton gradient across the vent membranes that had the same polarity (outside positive) which is similar to the electrochemical potential as modern cells have. This might be the reason that last universal common ancestors of all the three domains have evolved proton pumps.
Answer:This relationship is an example of a morphological similarity reflecting a likely evolutionary link
Explanation:
Lungfish and Coelacanths are distinct from other fish because they are lobe-finned species.
Lately, major palaeontological studies proposed that Lungfish and Coelacanth form a monophyletic sister group that is related closely to the tetrapods.
A monophyletic group is a group of organisms that include all the descendants and they share a common ancestor.
Based on the information above, the correct answer to the question would be a. Percy will likely make an external attribution. Since he does not remember anything that would cause him to think that he can be a reason why one of his windows is broken, then he most probably will attribute it towards an external event.
