2. Although vitamins and minerals are vital for the proper functioning of human cells, excess intake of certain vitamins and minerals can have deleterious consequences in the human body. Suppose you were to ingest all vitamins and minerals daily, but in slightly excessive amounts each day, over a long period of time.

Which effects would you expect to observe first: those of an excessive intake of watersoluble vitamin, or those of an excessive intake of a fat-soluble vitamin, or those of excessive intake of a mineral? Briefly explain your reasoning.

Which effects would you expect to be easier to reverse: those of an excessive intake of water-soluble vitamin, or those of an excessive intake of a fat-soluble vitamin, or those of excessive intake of a mineral? Briefly explain your reasoning.

Black-yellow cancer tissue c, substrate d consisting of fibrous crystals surrounding the radius. tissue e. tissue consisting of two seven-way crystals with distinct size differences. assembly tissue g. consisting of crystals of almost the same size. an organization consisting mostly of large crystals of a diameter of more than lcm.

The following is a description of the terms used to describe igneous rock tissue. What is the appropriate term for each explanation?
a. a gaseous air gap
b. Obsidian tissue
c. a substrate consisting of serpentine crystals surrounding the reaction.
d. tissue whose crystals are too fine to be seen without a microscope.
e. an organization consisting of two crystals with distinct size differences.
f. assembly tissue consisting of crystals of almost the same size.
g. a tissue consisting of large crystals of most diameter over 1 cm.

A is called porous tissue and B is called hyaline tissue, but I don't know the answer to f. Let me know which organization f belongs to.
