Answer:
B
Explanation:
because it is the right answer
Answer:
No, they order in sequences of base pairs in DNA
Explanation:
As you know, there are four nucleotides: Adenine, Thiamine, Cytosine, and Guanine. Adenine and guanine are purines, and cytosine and guanine are pyrimidines. You might not know what that means, so just in case purines are longer and pyrimidines are shorter. Therefore, A pairs with T and C with G. These pairings, along with other structural enzymes, build strands of DNA in the nucleus. I hope that helped, if you have more questions just let me know.
Answer:
Air moves into the lungs from atmosphere
Explanation:
As per the gas law, pressure of a gas is indirectly proportional to the volume of the gas. Thus, if volume increases pressure decreases.
Here, the volume of alveoli has increased due to which the pressure within the alveolar space reduces such that the atmospheric pressure outside alveoli becomes higher than the alveolar pressure within the alveoli. Due to this difference in pressure, the air gushes into the lungs.
