Answer:
70 ml/beat.
Explanation:
Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.
The stroke volume can be calculated by the formula as follows:
Stroke volume = End diastolic volume - End systolic volume
Here, end diastolic volume = 120 and end systolic volume = 50.
Stroke volume = 120 - 50
Stroke volume = 70 ml/ beat.
Thus, the answer is 70 ml/ beat.
The pair of magnets and a pair of water molecules are most likely similar. It is because the pair of magnets connects positive to negative and negative to positive, which is also similar to water molecules where they also connect to positive to negative.
The force of gravity is a major force that created the earth. As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.
Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.
Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo effect of the outer core so the earth is protected by its magnetic field.
The answers would be:
False
True
True
False

The oceanic crust is formed from the volcanic vents that erupt under water. The rocks that are formed from these eruptions are mafic, because they are compose magnesium and iron. Examples of mafic rocks are basalt and gabbro.
The Earth is made up of several layers. The deeper you go, the more heat and pressure. It gets really hot at the core because of different factors. One of them is the outer core and the inner core. The outer core flows around the solid core, which creates friction, thus creates heat. The outer core is also responsible for the electromagnetic property of the Earth.
Because seismic waves behave differently when they encounter different materials, geologists are able to use this to determine the different states of the layers beneath the Earth's surface. It helps them to determine whether the layer is molten, semi-molten or even solid.
The core is not the Earth's outer skin. The layer described is actually the CRUST. The core is the deepest layer of the Earth. It is solid and mostly made up of iron. The crust on the other hand is the outermost layer, and it is the layer that we live on.
