That's intimidating, lol!
Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.
Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.
Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.
Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.
This means that choice A is true!
The nucleotide adenine forms a bond only with the nucleotide thymine. Therefore, if 13% of the DNA strand is adenine, 13% of the DNA strand will be thymine. Therefore, the correct answer is a: 13%.
Answer:Neurons are specialized to transmit information throughout the body. These highly specialized nerve cells are responsible for communicating information in both chemical and electrical forms.
Explanation:
<span>In asexual organisms variation can occur from a variety of sources - mutations, homologous recombination and plasmid transfer. Mutations occur at a rate of roughly one base per million, meaning you would get between 0.1 and 10 in bacteria due to the size of their genomes.
In sexually reproducing organisms there are mutations and the crossing of gametes. The mutations occur in a near identical way to in asexual reproducing organisms as long as they occur in germline cells.
Asexually reproducing organisms reproduce much, much faster and so variation can occur more rapidly. For example the variation in the HIV viral propulation in an individual after 5 years is an immense diversity, higher than all the diversity that the human population has managed in thousands of years.</span>
