The right answer is A.) DNA in mitochondria .

Eukaryotic cells, with their many intracellular organelles, have long been considered progeny of prokaryotes that would have become more complex as a result of genetic mutations. But from the 1960s, biologist Lynn Margulis proposed an alternative explanation that was first received coldly by the scientific community. His endosymbiotic theory, proposed in a more formal way in a 1981 book, proposes that eukaryotic cells as we know them today would be the result of a series of symbiotic associations with different prokaryotes.

Mitochondria and chloroplasts also have their own DNA that is not trapped in a nucleus, which is also the case with prokaryotes. However, the proteins encoded by this DNA do not cover all mitochondrial proteins. The prokaryote is thought to have lost some genes to the nucleus of the cell, a process known as "endosymbiotic gene transfer". For this reason, mitochondria and chloroplasts are now host-dependent for the synthesis of most of their components.

Alekssandra [29.7K]

Answer:

brown bear

Explanation:

Brown bears have long, intimidating claws. However, since they are not retractable, they are relatively blunt and are usually used for digging. These bears are incredibly strong, able to break the necks of many large prey with one powerful blow. Their thick fur and layer of fat help to insulate them against the extreme cold temperatures of their habitat.

16. Why should the recessive phenotype be used first to determine the q squared value instead of the dominant phenotype to deter
podryga [215]

The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.

<h3>What is a recessive phenotype?</h3>

A recessive phenotype is a phenotype which expresses the recessive trait of a gene.

The recessive phenotype is always h0m0zygous for that triat to be expressed.

In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:

  • p^2 + 2pq + q^2 = 1

where;

  • p^2 is the h0m0zygous dominant phenotype frequency
  • 2pq is the heterozygous phenotype frequency
  • q^2 is the h0m0zygous recessive phenotype frequency

Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
