Hey there!
Your question states: <span> Explain why cells are so small, considering the relationship between surface area and volume for objects of different sizes but similar shapes.
Cell's are small because the size of the other surface area's and also there volume would obviously be bigger than the cell it self. So, they are basically bigger based on that it</span><span> is the most efficient at their </span><span>size. Cell's can not be big and there on some one's hat, that would be very weird. This would be why cell's are the size that they are.</span>
Answer:
Responding to stimuli / the environment
Explanation:
Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.
The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.

Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct
