sattari [20]

<em>Full Question:</em>

<em>Which tissue is correctly paired with its primary cell type?</em>

<em>bone: osteoblast</em>

<em>connective tissue proper: chondroblast</em>

<em>cartilage: fibroblast</em>

Explanation:

<em> </em><u><em>bone: osteoblast</em></u>

<u><em></em></u>

<u><em></em></u>

Osteoids comprise, significant sections of the entire bone matrix, and  this includes fibers of collagen which give bone its flexibility and mechanical strength this allows born to resist stretching and twisting forces.

Osteoblasts are highly specialized cells within bone which formulate new bone through the production or secretion of parts of the organic matrix; this is referred to as the osteoid and mediate the calcification (fortification with allium) of osteoid during the formation of mature bone matrix.

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.
