The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.
According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.
The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.
In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.

Answer: d) binding of keratin to cadherine) assembling keratin fibers
Explanation:
The desmos (membrane domains that facilitates the cell-cell contact) like cadherins are able to provide the strong adhesion to the intermediate filaments between the epithelial cells and muscle cells. The binding of the cadherine with the keratin fibers helps in providing the strong connection and adhesion of cell to cell in epithelial cell layers.
Due to mutation of the acidic keratin epithelial cell a fragile epithelial cell layer develops this will lead to disassembly of the keratin epithelial cells or will prevent the assembly of the keratin epithelial cells.
True!!
Eukaryotic DNA never leaves the nucleus; instead, it's transcribed into RNA molecules, which may then travel out of the nucleus.
Answer:
They add things that force the waves away, which prevents tsunamis. This also helps prevent death.
Explanation:
Things like dense mangrove habitats reduce the force of waves and reduce the pressure. Coral reefs may be artificially constructed. these have been shown to reduce the impact of tsunamis. Better education of residents about evacuation procedures. This is in case the tsunami isn't "sterilized".
