Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are all of the following except __________.
hodyreva [135]

Your question was incomplete (please check below the full content). The evidence that supports the prokaryotic origins of mitochondria and chloroplasts do not include multiple DNA copies associated with inner membranes.

<h3>What is organellar DNA?</h3>

The organellar DNA is the genome contained within mitochondria and chloroplasts, which is independent of nuclear eukaryotic DNA.

The organellar DNA contains multiple DNA molecules, which are found in association with the inner membrane, ant is not found in prokaryotic life forms.

The complete question in this case is: "Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are the presence of mitochondria, a eukaryote engulfing prokaryotic photosynthetic cells, and non-photosynthetic eukaryotes, EXCEPT."

The endosymbiotic theory states that mitochondria and chloroplasts evolved from prokaryotic microorganisms that entered into a primitive eukaryotic cell.

This theory is supported by certain features of mitochondria and chloroplasts such as a similar size to prokaryotes.

In conclusion, evidence do not include the arrangement of the organellar DNA.

Ccording to the Punnett square for this cross, what percentage of offspring is predicted to have blue feathers?
barxatty [35]

According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.

<h3>What is Punnett Square?</h3>

Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.

The complete question is described in the image given below:

When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.

In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).

Therefore, the correct for this question is B.
