The concept presented to explain the origin of eukaryotic cells, namely that a bacterial cell parasitized another descendant cel
son4ous [18]

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.

The human hands and feet have similar types and numbers of bones. However, hands and feet are very different in their appearance
Ira Lisetskai [31]

<u>Explanation:</u>

One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.

Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.

  • If for example, we were to walk with our hands we will fail to achieve stability.
  • And if for example, we decide to grab hold of items with our feet we will be unable to do so.

It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
