Answer:

B)  Iodine

Explanation:

Some mineral elements are required in very low quantities by humans, but they are essential for growth, development and nutritional quality, for example, iodine (I), zinc (Zn), and selenium (Se). Nutritionally deficits of these elements are considered a public health problem. However, iodine is an element that works as an antiseptic, which means <u>it kills microbes</u>, penetrating the cell wall and inactivating cell components, its use in medicine is well known. On the other hand, Calcium, Sodium, and Phosphorus, are elements that are fundamental for both humans, plants, and microbes.

Answer:

B) Iodine

Explanation:

Iodine is related with plants and bacteria is in the form of antiseptic, to <u>eliminate microorganisms</u>, but is not linked to either metabolism.

Calcium, sodium and potassium are nutrients directly linked to the metabolism of bacteria and the formation of chemical compounds for various reactions in bacterial cells.

In plants, <u>calcium</u> is primarily responsible for plant structure and cell wall formation. <u>Potassium</u> is important for controlling the amount of water in plants and for activating various enzymes. The function of <u>phosphorus</u> is related to the formation of chemical bonds and sometimes it can be used as an energy reserve.

These all are present in liver and kidney of human as well rat. In liver rapidly fructose is change to fructose 1 through fructokinase.

loris [4]

Chromosomes exchange genetic material in step 3.

<h3><u>Explanation</u>:</h3>

The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.

The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
