Which system is least affected by starvation? a. muscular b. nervous c. skeletal d. cardiovacular

C. Skeletal

Explanation:

Starvation is the physiological sensation one feels when the body needs nutritional replacement. Ghrelin, a hormone released by the stomach when it is empty, acts directly on the brain causing the sensation of starvation to be activated. This sensation interferes with the functioning of many body systems such as the muscular, nervous and cardiomuscular system. By eating any food, the stomach in turn releases the hormone PYY which by acting equally in the brain releases the feeling of satiety and stopping the discomfort.

Although it affects various body systems, the sensation of starvation does not interfere with the functioning of the skeletal system.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!

the answer is c teaching students and collaborating with teachers on instructional content.
