Explanation:
Exothermic reaction are those reaction in which energy is released as a product. The temperature of the surrounding increases.
Exothermic reaction are those reaction in which energy is absorbed by the reactants . The temperature of the surrounding decreases.
A) In process-2 , glucose molecule is broken down into water and carbon dioxide along with the release of an energy. This reaction is an example of exothermic reaction.
B) In process-3,4, glucose molecule is broken down into respective product along with release of energy.
C) Process -1 ,2.
Process-1 chemical representation of photosynthesis process found in plants .
Process-2 chemical representation of cellular respiration are found in plants cells.
D) Process-2,3.
The process -2 is a chemical representation of cellular respiration and process -3 is a chemical representation of anaerobic cellular respiration(takes place in the absence of oxygen).

Explanation:
Wegener was intrigued when the same Mesosaurus fossils, an ancient freshwater reptile, showed up on different continents.
What hypothesis did he propose to explain this?
A: The continents were at one time joined together.
B: The Mesosaurus swam between the two continents.
C: The fossils were moved by humans.
D: The fossils must be of different species.
Wegner simply defined it by saying that the continents were all together at one point in time. He defined this by explaining his Continental Drift theory. Hence option A is appropriate.
Alfred Lothar Wegner as is known as one of the foremost and most important people of his time. He was a Geologist as well as a climatologist.
Wegner during his time as a Geologist had given a path-breaking discovery that later the world cherished and became a ground for a lot of future generations. After, looking at the work of the solid spheres over time, and also by finding the Mesosauraus Fossil he could only come to the idea of Continental Drift Theory.
The Continental Drift Theory is such that, Wegner believed that during the Ancient Greek Civilizations, Earth was one big continent., Later on, the Pangea of the whole continent broke, and thus fragments of the continents started to float around and got separated. Hence, option A is correct.
