2 answers:

6 0

The answer is : DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil. Hope this Helps! Good Luck!

Answer:

DNA:

Deoxyribonucleic acid acts as the genetic material of almost all the living organisms. The deoxyribose pentose sugar is present in its DNA structure. The nitrogenous bases present in DNA are adenine, guanine, thymine and cytosine. DNA is highly stable in nature and cannot acts as the catalyst.

RNA:

Ribonucleic acid acts as the genetic material in case of few viruses only. The oxyribose pentose sugar is present in RNA structure. The nitrogenous bases present in RNA are adenine, guanine, cytosine and uracil. RNA is highly unstable in nature and acts as a catalyst.

How much charge does a 9.0 v battery transfer from the negative to the positive terminal while doing 39 j of work?

sdas [7]

The work done by the battery is equal to the charge transferred during the process times the potential difference between the two terminals of the battery:
$W=q \Delta V$
where q is the charge and $\Delta V$ is the potential difference.

In our problem, the work done is W=39 J while the potential difference of the battery is $\Delta V = 9.0 V$ , so we can find the charge transferred by the battery:
$q= \frac{W}{\Delta V}= \frac{39 J}{9.0 V}=4.33 C$

A minimum temperature thermometer in a standard weather instrument shelter measures an overnight low temperature of 36 degrees F

Rudiy27

Answer:

Explanation:

Even though the minimum temperature is more than the freezing point, Frost was observed on the ground because the ground will cool rapidly as cool air tends to move towards the ground, the temperature of the ground is lower than the atmosphere a few feet above it.

As the thermometer is kept some feet above the ground so ground temperature may be lower than the minimum recorded temperature.
