Hmm this is a rough explanations but because to be sure cells are made properly and not misfunctioning or going Rouge.
Cancer cells is an example of this, a cell goes rouge and starts doing it's function on it's own but outside of it's brother cells function slightly different turning into a growth or etc. The body thinks it is normal during the check body it's composed of the dna that passes this check.
viruses and other things don't pass this check and things like white blood cella come shut it down.
that's why doctors poison the area they find the cancer. to send white blood cells there to shut the area down not passing the check.

<span>d. culturing unknown organisms </span>
<span>e. amplification of DNA for microbe identification</span>
Answer:
The correct answer is multicellular organisms.
Explanation:
Organs are differentiated structure formed by group of cells and tissues to perform the similar functions. When more than two organs perform specific function in a coordinated manner they form organ system.
Tissues and organs are a characteristic feature of multicellular organisms as more than one cell is present in these organisms and these cells aggregate together to form tissues, which further aggregate to form different organs carrying out the different functions attaining complexity.
Since, unicellular organisms do not have more than one cell, unicellular cells do not form tissues and lack organs.
Thus, the correct answer is multicellular organisms.
which is absent in unicellular organisms.
