As the exercise progresses, muscular activity increases venous return. This increases the pre-load on the right ventricle. During venous exercise, the rhythmic pump of the muscles facilitates venous return by forcing the blood through one way valves that lead to the heart. Additionally, increased lung activity which creates a change in thoracic pressure that draws blood towards the heart. Regular exercises improves the venous return by increasing total blood volume, increasing end diastolic volume and increasing the size and contractile strength of the heart muscle.
DNA is inside the nucleus and the tRNA copies the message and the mRNA take it to the nucleus
Deletion is just the removal of one of the nucleotides. Therefore, the new sequence would be:
CCU...AGG...UCC...UG
(Basically everything moves over one)
Answer:
Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth’s, much higher than anywhere else on the Sun. … This in turn lowers the temperature relative to it’s surroundings because the concentrated magn fields inhibits the flow of hot, new gas from the Sun’s interior to the surface.
