There were A adults, Sm male students, and Sf female students.
<span> </span>
<span>Sm = 1 + 7A </span>
<span>Sf = Sm/2 </span>
<span>A + Sm + Sf = 82 </span>
<span>A + (1 + 7A) + (1 + 7A)/2 = 82 </span>
<span>2A + 2 + 14A + 1 + 7A = 164 </span>
<span>23A + 3 = 164 </span>
<span>23A = 141 </span>
<span>A = 7 </span>
<span>The number of male students is 50. </span>
<span>The number of female students is 25.</span>

Explanation:
Lesch Nyhan syndrome is characterized by behavioral and neurological abnormalities, and excess uric acid production in the body. It occurs in males, almost exclusively.

Hence, the correct option are a. and c.
Answer:
Explanation:
During a physical change, the arrangement of particles may change but the mass, number of atoms and number of molecules will stay the same. ... During a chemical change, the mass and number of atoms is conserved, but the number of molecules is not always the same. Chemical reactions involve large changes in energy.
The two organelle that convert energy into plants are Chloroplasts and Mitochondria.
Explanation:
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
