How the need for iodine or iron in the diet differs from that of calcium or phosphorus. Introduction: Essential elements are the natural elements that are needed by an organism for healthy living and biological functions such as growth and reproduction. There are about 25 essential elements required by the human body. Trace elements are the essential elements that are only needed in very small quantities by living organisms, and constitute only 0.01 percent of the biomass. Some examples of trace elements are iron, boron, cobalt, magnesium, molybdenum, tin, zinc, fluorine, cobalt, boron, chromium, and selenium. The elements that are required in a much larger quantity are called macroelements.

Expert Solution & Answer

Explanation of Solution

Calcium and phosphorus are important components of bone and teeth. The body requires higher quantities of calcium and phosphorus. Iodine and iron are the important elements required by the body in trace amounts. Iodine is an essential ingredient of the thyroid hormone produced by the thyroid gland. It is required by vertebrates. Iron is required by all forms of life. It is an important component of hemoglobin.

Conclusion

The body requires higher quantities of calcium and phosphorus and lower amounts of iodine or iron.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
