3- both of them contain the nitrogenous bases adenine, cytosine and guanine.

differences:

1-DNA is longer

2-DNA is the storage form of all genes while RNA has 3 types. messenger RNA which is a message of certain codes,  ribosomal RNA which enters in the structure of ribosomes (synthesize proteins) and transfer RNA which carries amino acids and helps in transcription process.

3-DNA contains thymine base while RNA contains uracil

4- DNA is more stable and not easily hydrolyzed.

This aquifer supplies one-third of the irrigation water in the United States
N76 [4]

<u>ANSWER:</u>

Ogallala aquifer supplies "one-third of the irrigation water" in the United States.

<u>EXPLANATION:</u>

  • The aquifer supplies water for one-third irrigation needs of the United States. The Ogallala is an underground reservoir and is very big in size and the agriculture production in the US is dependent on this aquifer.
  • The aquifer is however depleting and water level in many areas has become very low.
  • It is important for United States to protect and preserve this aquifer so that the agricultural production does not suffer.

Which of the statements about half-life are true?
Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.
