The generalization that all organisms are composed of cells was established through multiple observations in various kinds of animals and plants. A controlled experiment of finding cells in all the kinds of living organisms is not possible or is infeasible as it will require prior knowledge of all the kinds of organisms inhabiting Earth and the effort to catch and bring them in the controlled environment of the lab for testing.
Answer:
Phoebus Levene( 1896, Sagor Russia - Septemeber 1940, New York)
Explanation:
These were developed by Phoebus Aaron Theodor Levene ,he was a russian who studied medicine, with keen interest in organic chemistry.
He migrated to the US in 1891, and started practising medicine in 1892.Due to his strong interest in research he combined research(1894) in molecular structure of sugars with medical practice,But this was cut short when he contracted tuberculosis.
Between 1896- 1906,he collaborated with many nucleic acids and protein exoperts e.g Albrecht Kossel and Emil Fischer to wok on the structure of DNA.And headed the Rockefeller Institute for Medical Research.
He works included :the isolation of Nucleotide-monomers of DNA
:the isolation of D-ribose sugar from ribonucleic acid molecule.(RNA)
Discovery of 2-deoxyribonucleic ,
How the components of Nucleotide(phosphate group,sugars, and organic bases) combined to form nucleotide, and how the latter undergo condensation reaction to form DNA.

- The Komodo dragon can can reproduce sexually or asexually depending on their environmental conditions. At most zoos, females live alone and are kept separate from other dragons.
- <em><u>The females Komondo dragons can produce babies without fertilization by a male. This process is called parthenogenesis or a virgin conception.</u></em>
Answer:
An adequate way in biology has classified and ranked the levels of organization of genetic information
1. DNA: refers to the double helix.
2. Nucleosomes: they are the first level of DNA curl. They are formed by a protective core of 8 histones, around which the double helix of DNA is inscribed.
3. Chromatin: is the set of nucleosomes, is composed of histones, other DNA and RNA proteins
4. Chromosome: it is the condensed chromatin
The function of a renal artery (blood vessel) is to carrie oxygenated blood to your kidneys, whereas the function of pons is to relay messages from the cortex of the brain to the cerebellum. It serves as a message station between several areas of the brain.
