Answer:
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%
Sowe actually would need like 5 Earths.
So none of the options is matches this, but this may be because this question is about some specific resources and not for the specific energy used. The closest option is 200%
<span>At the end of meiosis II, compared to the DNA from the original cell, the DNA in each of the four new cells is C)half as much and genetically different from the original. Meiosis is the type of cell division in which the genetic material is reduced by half. Thus, choices B and D are incorrect. Further, the exchange of genetic material between homologous chromosomes so-called the crossover occurs during meiosis, so DNA in new cells will be genetically different from the original DNA. Thus, the correct choice is C.</span>
Answer:
Polymers are made from a chain of one similar subunit bound together in sequence. Proteins are made from polypepetide chains which are sequences of amino acid subunits. Another example of polymer is DNA and RNA made of nucleic acid subunits.
However, lipids do not have one similar subunit but rather variable ways in which the lipid chains can form. For example phospholipid unit is made of a phosphate molecule bound to a fatty acid chain and glycerol. A triglyceride is a subunit of glycerol bound to three fatty acids chains. Cholesterol is also considered a lipid but is made of carbon rings rather than chains. Lipids therefore cannot be referred to as a polymer.

If there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, the allele frequency of b is 50%.
Allele frequency, sometimes referred to as gene frequency, is the percentage or fractional frequency of an allele (gene variant) at a certain location in a population. What is being discussed is the proportion of chromosomes in the population that carry that allele in comparison to the entire population or sample size. The slow change in allele frequencies within a population is known as microevolution.
Taking into consideration:
1. A particular allele at a particular chromosomal region.
2. A collection of N individuals with ploidy n, which denotes that each individual's somatic cells have n copies of each chromosome (e.g. two chromosomes in the cells of diploid species).
If an allele is found in a population on I chromosomes, the allele frequency is the proportion of all I occurrences of that allele to the total number of copies of the chromosome in the population (nN). Despite being related, the genotype frequency and the allele frequency are separate and one can infer the other from the other.
