Answer:
Which statement best compares a eukaryote and a prokaryote?
A. Eukaryotes have a cell wall, while prokaryotes have a cell membrane.
*B. Eukaryotes have membrane-bound organelles, while prokaryotes have few specialized
structures.
C. Eukaryotes use active transport to move substances across the cell membrane, while
prokaryotes use facilitated diffusion.
D. Eukaryotes use flagella to move themselves through substances, while prokaryotes are not
able to move.
Explanation: its B
Answer:
The resulting molarity is 6M.
Explanation:
A dilution consists of the decrease of concentration of a substance in a solution (the higher the volume of the solvent, the lower the concentration).
We use the formula for dilutions:
C1 x V1 = C2 x V2
12 M x 0,5L = C2 x 1,0 L
C2= (12 M x 0,5 L)/1,0 L
<em>C2= 6 M</em>
Hi , I’m really sorry because I just have the first question... so here it is :
So it is 0.52 mol .
Have a nice day .
Answer:
A)The characteristic frequency to look out for is 1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.
B)Characteristic frequency present in the infrared spectrum will be at a peak of 3300-3400 cm-1 which will be due to O-H stretch.
C)If the product is wet with water there will be no change in the infrared spectrum
Explanation:
The characteristic frequency to look out for is 1720-1740 cm-1 (for C=O) for which will disappear in the end product but initially present in the reactant.
Characteristic frequency present in the infrared spectrum will be at a peak of 3300-3400 cm-1 which will be due to O-H stretch.
If the product is wet with water there will be no change in the infrared spectrum
