Birds
Birds are organisms which utilize a one-way air flow through their lungs to maximize air flow efficiency and <span>oxygen consumption
</span>The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes OXYGEN <span>from the atmosphere and produces and releases </span>CARBON DIOXIDE to the atmosphere.answer is letter D.
<span>Respiration driven by a mechanical series called inhalation and exhalation. We inhale or breathe in oxygen and exhale or breathe out carbon dioxide. </span>
Answer:
option 1
Explanation:
In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.
