Your friend is trying to convince you that if the ligaments binding the bones together at your freely movable joints (such as yo

ur knee, shoulder, and hip joints) contained a higher percentage of elastic fibers, you would be much more flexible. Is this true? If so, would this present any serious problems?

If the ligaments of the joints contained high percentage of the elastic fibers then, the joints would have been more freely movable. They would be more stretchy and flexible. But the ligaments around the joints keep the bones together and aid in the controlled movements of these joints. If the percentage of the elastic fibers in the ligaments joining these is to be increased, then the joints will become floopy and will be prone to dislocation and misalignment.

Answer:

If ligaments comprise greater number of elastic fibers they would become more stretchy, therefore, the joints would turn out more flexible. Though the prime role of the ligaments is to join bones together in a secured manner so that proper monitored movement of joint can take place.  

The presence of greater number of elastic ligaments would lead to floppy joints in which the bones taking part in the joint would become more vulnerable to dislocation and misalignment.

In a two-compartment model of a cell with a K - and Cl --permeable membrane and a 10-fold excess of KCl in the inside compartmen
Keith_Richards [23]

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.

Androgynous behaviors are solely the product of biological sexual differences.
xxTIMURxx [149]

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.

Approximately 40% of the energy stored in sugar molecules is converted into energy. What happens to the remaining 60%?
Vaselesa [24]
<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.
