Which two scientists are accredited with correctly deducing the double helix model of dna.
Vika [28.1K]

Answer:

James Watson and Francis Crick

Explanation:

Watson, Crick, Franklin, and Wilkins were four scientists that discovered the double-helix structure of DNA, which served as the foundation for modern biotechnology.

Franklin used X-ray crystallography at King's College London to acquire pictures of DNA, a notion previously proposed by Maurice Wilkins. Franklin's photographs led James Watson and Francis Crick to develop their renowned two-strand, or double-helix, model.

Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️

In the following image, what conclusion can you draw about the speed of the planet at location A compared to location B? (2 poin
aleksandr82 [10.1K]

The answer is; When the planet is at A it is moving faster than at B.

This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.
