The answer is 800 meters.
You find this by taking the total distance of the first lap and doubling it. You could also find it by adding 400 meters to 400 meters, which would total at 800 meters
Answer: The daughter cells develop after the cell division will have unequal number of chromosomes.
Explanation:
The interphase is the stage of the cell cycle in which the parent cell prepares itself for division. It increases in size and develops organelles for cell division. Before the cell division the replication of the genetic material in the form of DNA is necessary so that both daughter cells receive equal amount of genetic material after the cell splits by mitosis. Mitosis is a cell division in which the parent diploid cell splits into two haploid daughter cells. Each daughter cell receives the half the chromosomes as that of the parent cell.

After two half-lives or 60 years, 7.5 g of the element will be left.
<u>Explanation:</u>
<u>Half-life:</u>
- In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
- In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
- After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
- And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
- After two half-lives or 60 years, 7.5 g of the element will be left.
