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.
Option A is correct. After making a punnet square, we can see that the genotypic ratio would be 1:2:1, being 25% dominant, 25% recessive and 50% heterozygous. However, we are asked for the phenotypic trait percentage. The phenotypic ration is 3:1, with 75% polka dotted tail (dominant gene active) and 25% solid tail (recessive gene active).
Pls thanks + branliest :P
<h2>
Zone of physiological stress</h2>
Explanation:
For this particular species I would label 90°F to 94°F as the temperature zone of physiological stress.
We find that within this temperature range the number of individual in the population lessens. This means they are under certain physiological stress which limit there growth.
Again within 95°F–96°F we find that the number of individual is maximum. This means that the population can utilize the available resources to their maximum efficiency at this range. So, it is the optimum range.
<h2>Answer:</h2>
Option B is correct.
B. How ecologically sensitive the area is, and how the activity would impact the benthic organisms.
<h2>Explanation:</h2>
Being the marine biologist It will be my first concern to see and bind its impact on marine life and benthic organisms. It will find that how ecologically sensitive this area is and how it is going to affect the activity of marine life. Because marine life is my priority being the marine biologist.
