Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.

Androgenous behaviors is not solely the product of biological sexual
differences, such as the ability to bear children. It is also regarded as product of evolution
and natural selection where an individual may be androgynous, displaying feminine and
masculine characteristics or traits based on one’s gender identity and learned
gender role. This can be made possible through the ongoing social interactions
that individuals have with each other.

<h3>Answer</h3>
Approximately 40% of the energy stored in sugar molecules is converted into energy and the remaining 60% is wasted as heat energy.
<h3>
Explanation</h3>
Cellular respiration is the process which take place inside a living organism by which organic compounds, usually carbohydrates, are broken down releasing energy that is used to produce ATP molecules that supplies energy/power to cells.
<h3>Example of respiration</h3>
C6H12O6 + 6O2 —– enzymes & coenzymes ——> 6CO2 + 6H2O + Release of Energy (≤38 ATP) + Heat
So, 40% of the available energy of glucose is release as ATP and the remaining 60% is lost as heat and helps to generate your relatively high body temperature.
