Answer:
We can easily find out the beginning point of the line by using dot representation. When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system. The vector is a straight line that has a certain end which is fixed to its body.
<span>Meiosis I
Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span>

Answer:
The correct answer is option c. Haploid spores.
Explanation:
In the plants, spores are normally unicellular and haploid and produced by the process of meiosis in the sporophytic body of the plant.
These haploid spores undergo the mitotic division and develop a new individual called gametophyte that forms gametes eventually.
Thus, the correct answer is option C. Haploid spores.
Answer:D
Explanation: Because it has the least amount of density in it. All the others are heavier, meaning they will sink. Just like if you drop a rock water and a feather, the feather will float.
Density def:
Density, mass of a unit volume of a material substance. ... Density offers a convenient means of obtaining the mass of a body from its volume or vice versa; the mass is equal to the volume multiplied by the density (M = Vd), while the volume is equal to the mass divided by the density (V = M/d).
