The answer is; E
This shows that these organelles were once free-living organisms with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.
Answer:
Dominant: 20, Recessive: 20
Explanation:
The case shown in the question above explores simple Mendelian traits, since it shows a population where individuals of the same species present the dominant allele (R- red) and the recessive allele (r- white). We can project, then, that this population has an allele balance, where it is possible to find 20 red beans, which have the dominant allele and 20 white beans, which present the recessive allele.
B, because as energy is move up form the phyramid, energy is lost.
The organelles that produce proteins used within the cell are the ribosomes.
Final answer: Ribosomes.
