Well thats ur opinion some people might not think it is hard
You never can know the exact value of a physical or chemical dimension because several reasons: all the instruments have a certain sensibility (sensibility is the smallest variation of the dimension that the instrument can measure) that cannot be overcame.
The rRNA signature sequences can be used to place microorganisms in the correct domain is <u>True</u>.
rRNA- All cells require ribosomes, which are the main building block of non-coding RNA known as ribosomal ribonucleic acid (rRNA). Protein synthesis is carried out by rRNA, a ribozyme, in ribosomes.
Signature Sequence- Proteins having a certain structure or function have continuous patterns of amino acids 10–50 residues long known as signature sequences.
Microorganism- A living thing that can only be observed under a microscope. Protozoa, algae, fungus, and bacteria are all examples of microorganisms. Viruses are occasionally categorized as microbes even though they are not thought of as living things.

Answer:
Schwann Robert Hooke
Explanation:
He discovered a honeycomb like structure in a cork slice using a primitive compound microscope. He only saw cell walls as he was looking at dead tissue. Hooke coined the term "cell" for the individual compartments he saw
