Explanation:
the molecules of chlorophyll absorb the sun's energy in form if light
It is about 4.22 light-years<span> from Earth and is the closest star other than the sun. Alpha Centauri A and B orbit a common center of gravity every 80 years. The average distance between them is </span>about 11 astronomical units<span> (AU) — about the same distance as the sun is to Uranus.</span>
This would affect the population of the rabbits isf this happens the increase of population on the rabbits then if theres an increase on the rabiits then there will be a limiting factor of food for them this will affect the carraying capacity of the ecosystem
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.
