Answer/Explanation:
Killifish are unique in that their species contains a lot more genetic diversity than most animals. The genetic mutations that allowed some to adapt were already present in these populations. Species that are less genetically diverse may not have the right molecular tools to adapt.
Golgi apparatus is an organelle in eukaryotic cells that stores and modifies proteins for specific functions and prepares them for transport to other parts of the cell.
Its usually near the cell nucleus and consists of a stack of flattened sacs.
The intermediate molecule that is synthesized to carry the information coded in the DNA is RNA.
According to the central dogma the DNA gets converted to RNA by the process of transcription. Transcription synthesizes the RNA copy of the DNA segment with the help of an enzyme RNA polymerase. RNA then gets converted to protein by the process of translation.
The enzyme DNA polymerase is responsible to convert a single double-stranded DNA molecule to two double-stranded DNA molecules as its products. The DNA is converted to RNA through the transcription process. The enzyme RNA polymerase develops RNA molecule which is complementary to a gene-encoding DNA segment. Translation makes proteins from mRNA molecules. The ribosome is responsible to generate the polypeptide chain of amino acids using mRNA as a template. The polypeptide chain then folds up and becomes a protein.
The right answer is The cells are damaged.
Take the example of skin cells.
The skin consists of two tissues:
* the outermost, the epidermis, resting on a vascularized connective tissue,
* the dermis.
In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.
On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
The answer to your question is,
if the oxygen poor blood mixes back with oxygen rich blood, that means that oxygen poor blood is not going back to the lungs to swap CO2 (carbon dioxide) with O2 (oxygen), and this swapping is vital to tissue survival, since oxygen is what keeps your tissues, muscles, and organs alive. so if this blood mixed, ultimately your organs are not receiving enough oxygen and will become starved of it, this can kill you and lots of people every year get heart surgery because their atrium or ventricles in their heart rupture
