Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
Sediment. So the river picks up sediment when it is moving quickly and deposits it when it slows down (or when there is a bend in the river).
B, cold with a high salt content, I believe.
Since density is mass divided by volume, adding salt would increase mass.
Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles.
Generally cold water is more dense. Hope i helped :D
Al3+ represents aluminium ions
Answer:
Structure. The IVC is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord.
