Answer:
On the basis of Chargaff's rule, in a double-helical DNA, A = T and G = C (Here A means adenine, T means thymine, G means guanine, and C means cytosine. For X, A is given 32%, therefore, T must be 32%, and the leftover 36% is to be distributed equally between G and C. Thus, G = C = 18% each.
The assumption formed is that the DNA is a double-stranded structure. The species that exhibits higher G + C content in the molecule of a DNA is steadier at higher temperatures as it melts at high temperature. The species Y, which exhibits G + C in total as 66% is the thermophilic bacterium between the two.
Answer:
120 g
Explanation:
mass of reactants+ mass of products=one mole of oxygen= 120 g
I would say A. Quantitative data involves numbers and stuff like that. Unlike qualitative data, which involves pictures and not numerical data. I hope this helped.
Calculate the acceleration of a boat that has been cruising
at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2.
In order to calculate the acceleration of the boat we first
have to identify the suited formula for acceleration in this scenario.
Hence, a = vf – vi / t.
Vi = 15 m/s
Vf = 45 m/s
T = 6 seconds
Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2
