Answer:
The correct answer is option D. "generally is of higher velocity, although it is masked by reduced turbulence".
Explanation:
In most rivers, the downstream portion is both wider and deeper than the upstream portion. This means that there is more water in the downstream portion, which in consequence results in the river having a higher velocity. However, this is masked by a reduced turbulence since a higher amount of water tend to overcome more easily all the obstacles that can generate friction.
Calcium provides strength as a element, though it is present as calcium chloride on the exoskeletons.
Answer:
The circulatory system
Explanation:
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH,
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.
