Answer:
The Earth's crust is broken into plates that lie over the mantle. Because the mantle is hotter toward the interior and cooler toward the exterior, convection currents occur, which causes the plates to move above them. ... Volcanoes, earthquakes and mountain building or orogeny are found along plate boundaries.
Explanation:
Answer:
The correct answer would be option C.
Plants evolved different methods to prevent or reduce the effects of photorespiration.
The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.
The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.
In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.
The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.
The second law of thermodynamics states that not all of the energy is used because some of the energy is lost in the form of heat. The lost heat energy is an unusable form of energy, and it causes an increase in the entropy of the universe. Thus, no energy transfer process is efficient due to the loss of energy.
Answer:
The sites of replication.
Explanation:
Linear DNA is and advantage for bigger organisms because there can be many places where replication can occur, otherwise, in circular DNA replication can only happen in he ORI place, that is unique. This feature allows to replicate several genes in the same amount of time being more efficient in protein synthesis.
