Answer:
Row 1 
T-tubule
Dihydropyridine (DHP) receptors of the transverse tubule membrane play two roles in excitation-contraction coupling in skeletal muscle: (a) they function as the voltage sensor which undergoes fast transition to control release of calcium from sarcoplasmic reticulum, and (b) they provide the conducting unit of a slowly ...
Row 2
Sarcolemma
Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle.
 
        
             
        
        
        
Answer:
The correct answer is "Runaway sexual selection".
Explanation:
Runaway sexual selection, also known as Fisherian runaway in honor to Ronald Fisher the scientist that proposed it, is a type of sexual selection on birds, at which exaggerated male ornamentation are developed since females prefer males with these characteristics. Runaway sexual selection is a  biological paradox, since male with exaggerated ornamentation are selected by the females but also are more easily caught by predators. Runaway sexual selection fits the description of the species of bird herein described.

True.
In the upper layers of the atmosphere, it blocks UV radiation from the sun; however, in the lower layers, it is a pollutant.
