The level of DNA packaging brought about by the formation of nucleosomes looks like beads on a string.
<span> The DNA packaging process includes and describes how DNA is packaged so tightly into chromosomes and squeezed into a tiny nucleus.</span><span>
A </span>nucleosome<span> is a section of </span>DNA that is wrapped around a core of proteins.
Answer:
Explanation:
Cellular respiration is a process which occurs in the all living cell all the time. It is an oxidative process by which respiratory substrate such as glucose (C₆H₁₂O₆) is oxidised completely in presence of oxygen(O₂) to produce carbon dioxide (CO₂), water and energy in the from of ATP. ATP is is the energy currency of the cell. The process of cellular respiration begins in cytoplasm and completes in the mitochondria of the cell.
The overall reaction of respiration is given below:
C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + Energy (ATP)
Using photosynthesis, which consists of a series of chemical reactions that require carbon dioxide and water, and store chemical energy in the form of sugar. Light energy from light drives the reactions. Oxygen is released into the atmosphere as a byproduct of photosynthesis.
<span>This is the equation for photosynthesis: 6 CO2 + 6 H2O → 6(CH2O) + 6 O<span>2</span></span>
This increase in volume leads to a decrease in intra-alveolar pressure, creating apressure<span> lower than atmospheric </span>pressure<span>. As a result, a </span>pressure<span> gradient is created that drives air into the </span>lungs<span>.
