The mass would be 0.5kg
To find the mass of an object with acceleration and force would be
m = f/a
I hope this helps. Please rate Brainliest if it did :D
<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.
They combine to form traits.
