As it takes the sun about 250 million years to orbit the galaxy, the proper motion of stars relative to the Sun will be the dominant effect of changes in the sky. The visible effects of the rotation will be far slower.

All stars move in the sky, some faster some slower, and in more or less random directions, not just moving around the galaxy.

stepan [7]

Answer:

Chromosomes at the conclusion of Meiosis I  - 50

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells

Explanation:

Given

Number of chromosomes in the diploid cells of Aliens from the planet Zorg = 100

In the Meiosis I cell division , a cell divides to produce two diploid cells with exactly the same amount of  DNA  as that of original parent cell.

However, the number of chromosomes is reduced to  by half at the end of meiosis I

After Meiosis II, four haploid cells are produces with half the amount of DNA  as that of original parent cell

Thus,

Chromosomes at the conclusion of Meiosis I  - 50

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
