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.
The body temperature of the mammal will be higher than that of the reptile. this is because the mammal body temperature does not depend on its environmental temperature while a reptile does not have a stable body temperature and depend on the temperature of its environment.
The correct answer is option A - Lithosphere
Explanation:
John Tuzo Wilson was a Canadian geophysicist who is known for his contributions to the theory of plate tectonics.
Plate tectonics supports the idea that the rigid outer layer of the Earth or the lithosphere is broken into numerous plates. These plates move independently over the asthenosphere.
Correct answer: D). The organism is buried in sediment and then dissolved by underground water
Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.
The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.
