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:
Because the gene is an inheritance of our ancestors, weight is something you gain or lose depending on how balance your health is. The reason why our weight can't be controlled by the gene is because the gene has different traits coming from each parents(50%) and grandparents(25%), and either parents has different weight, so it will be hard for the gene to capture one specific weight from both sides.
Answer:
1- constitute cellular structures.
2- confer elasticity and resistance to órganos and tissues.
Answer:
B) the parasympathetic nervous system
Explanation:
The parasympathetic nervous system is a division of the autonomic nervous system. Once the stress or emergency conditions are over, the activation of the parasympathetic nervous system calms down the person. This division of the nervous system slows down the responses generated by the sympathetic nervous system during stress conditions. The parasympathetic nervous system activates digestion and absorption of the nutrients, slows down the breathing and heart rate so that the energy level of the body cells is restored. After a football game, the activated parasympathetic nervous system will calm down David.
