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.

Answer

given,

difference between the two consecutive maximum

λ = 0.870 - 0.540

λ = 0.33 m

speed of sound = 340 m/s

b) frequency of the sound

v = f x λ

340 = f x 0.33

$f =\dfrac{340}{0.33}$

f = 1030.3 Hz

a) phase difference

the expression of phase difference is given by

$\phi = \dfrac{2\pi}{\lambda}\ \delta$

$\delta = \Delta x - \lambda$

$\delta = 0.540 - 0.33$

$\delta = 0.21\ m$

now,

$\phi = \dfrac{2\pi}{\lambda}\ \times 0.21$

$\phi = \dfrac{2\pi}{0.33}\ \times 0.21$

$\phi = 3.99 rad$

What makes a clinical thermometer suitable for measuring small changes in body temperature? *

Nana76 [90]

Answer: Because of the fine bore of the tube.

Explanation:

Temperature is the degree of hotness and coldness. And thermometer is the instrument use to measure temperature.

The two most common types of themometric fluids for thermometer are alcohol and mercury.

What makes a clinical thermometer suitable for measuring small changes in body temperature is because of the fine bore of the tube which makes it possible for small temperature changes to cause large changes in the length of mercury columns, making the thermometer very sensitive to temperature changes.

The most prominent feature of the thermometer is the kink or constriction of bore near the bulb.
