What would go wrong if a cell did not replicate its DNA before beginning mintosis?
Anna35 [415]
If a cell did not replicate its DNA (during the S-phase) before beginning mitosis, then the two identical daughter cells would only get one chromosome from each pair. This, instead of the normal (diploid) 2 pairs of each chromosome (2×23=46), would lead to two haploid cells with 23 total chromosomes each. They would be unable to function and sustain life, thus would likely die soon after division.

If everyone on the planet used the same amount of resources as an average American, what percent of the Earth would
matrenka [14]

Answer:

D. 200%

Explanation:

While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.

Then, if the 100% of the population were like the Americans, we have:

5%*x = 100%

x = 100%/5% = 20

the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.

Then the energy that the 100% of the population would use is equal to:

20*24% = 480%

So we actually would need like 5 Earths.

The option is 200%
