The ocean’s sunlight environment is generally much richer in marine life closer to the continents than is the open sea farther from the continents. Explain why the open sea is sometimes called the blue

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

the answer is a) cell division.

hope this !

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
