<u>Answer:</u>
During Meiosis I the cell transform from diploid cell to haploid and ends after Telephase I.
<u>Explanation:</u>
The one and only purpose of Meiosis is to produce gametes-sex cells or sperm and eggs in the human body. The objective is to make daughter cells with precisely half the same number of chromosomes as the starting cell. In humans, meiosis is a cycle of division that .allows cell transformation from a diploid cell (one with two sets of chromosomes) to haploid cells (one with one set of chromosomes).
Their is a two-step division cycle in meiosis. During the first round of cell division, homologue pairs divide, called meiosis I. During a second round, sister chromatids split, called meiosis II. As the cell division during meiosis occurs twice, one starting cell can produce four gametes (eggs or sperm). Cells pass through 4 stages in each round of division like prophase, metaphase, anaphase, and telophase. The cycle can be understood as follows:
<u>Meiosis I: </u> Before entering meiosis I, a cell must under go an interphase. The meiosis-I involve prophase-I , metaphase-I , anaphase-I and telophase-I. The starting cell is diploid (2n=4)
- during prophase-I homologous chromosomes pair-up and exchange fragments called as "crossing over".
- during metaphase-I homologue pairs line up at the metaphase plate.
- during anaphase-I homologues separate to opposite ends of the cells and then sister chromatids stay together.
- during telophase-I the chromosomes reach at opposite poles of the cell and result each chromosome has two sister chromatides, non identical in nature.
- Finally the newly forming cells are "haploid" i.e n=2.

Answer:
Minerales
Explicación:
Los minerales son los componentes de los alimentos que mantienen las funciones energéticas, estructurales o reguladoras del organismo porque los minerales tienen nutrientes que nuestro cuerpo necesita para realizar funciones estructurales y reguladoras. Los minerales son muy importantes para la formación de enzimas y hormonas en nuestro cuerpo. Nuestro cuerpo necesita algunos minerales en grandes cantidades, mientras que otros en menor cantidad. Ejemplos de minerales son magnesio, hierro, zinc, yodo, cromo, cobre, fluoruro, calcio, fósforo, potasio, sodio, cloruro, molibdeno, manganeso y selenio.
Sammy might be suffering from Cerebral Palsy (CP), as only the motor functions of Sammy are suffering, but the intelligence is unaffected. CP can be defined as a neurological disorder which affecting the communication between the muscles and the brain which leads to the poor motor function. And because of this, the patient is unable to stand, coordinate, balance, or control his body movements. However,, Cerebral Palsy have no derogatory effect on the intelligence or the thinking of the patient.
