The
water cycle is the continuous movement of water on the surface of the Earth.
Its physical processes arranged in order involve: Evaporation, Condensation,
Precipitation, Infiltration, Runoff, and subsurface flow. Following the
evaporation stage is the process of condensation. Condensation refers to the
transformation of water vapor into liquid water droplets in the air. When this
happens, fog and clouds are formed on the atmosphere of the Earth.

The
water cycle may cause temperature and climate changes in the environment
because of the series of energy exchanges that occur during its different stages.
Aside from this, the cycle allows for the transportation of liquid into
different bodies of water around the world making it responsible for
maintaining most life and ecosystems in the planet. It also reshapes the
geological features of the Earth (e.g. erosion and sedimentation) </span>
Answer:
Which two mechanisms influence the force of cardiac contraction?
Answer: End diastolic volume and sympathetic nervous system stimulation
Explanation:
Blood pressure decreases during diastole, which occurs when the heart muscle relaxes. While, blood pressure increases during systole, which occurs when the ventricles contract, pushing blood out of the right ventricle.
The cardiovascular system connects a pump to blood vessels.
Cardiac contraction is the end result of action potentials and it can be defined as a unique ability of cardiac muscle to generate a force that is independent of any load or stretch applied.
End-diastolic volume is the amount of blood in the ventricles just before systole. A person’s end-diastolic volume tends to decrease with age.
End-systolic volume is used in the hospital to determine a measurement known as stroke volume, which is the amount of blood pumped from the left ventricle with each heartbeat.
Sympathetic stimulation causes the release of the neurotransmitter norepinephrine and it increases heart rate and myocardial contractility.
The sympathetic nervous system has a wide variety of cardiovascular effects, among which are, increased cardiac contractility, peripheral vasoconstriction.
Sympathetic nervous system stimulation causes vasoconstriction of most blood vessels.
Answer: option A (the first one)
