I don't know if this helps or not but you would want to know the age of the rock (absolute dating) and from there you will be able to know the age of the fossil and what caused it to die.

The proper function of the cardiovascular system relies on blood following the correct pathway through the heart. Valves within
Nadya [2.5K]

Answer:

The Mitral/Bicuspid Valve

Explanation:

The heart is composed of 4 chambers: left and right atria, and left and right ventricles. The “right heart” (right atrium and ventricle) receives deoxygenated blood from the systemic circulation through the Vena Cava, and impels this blood towards the lungs through the Pulmonary Arteries where it will be oxygenated. The “left heart” (left atrium and left ventricle) receives oxygenated blood from the pulmonary circulation through the Pulmonary veins and impels this blood towards the systemic circulation through the Aorta artery.

The systemic and pulmonary circuits work in series, and maintaining the unidirectional course of the blood flow is very important. This can be done by the presence of fibrous valves that are present between the atrium and the ventricles, and in between the ventricles and the Pulmonary/Aorta artery.

The location of these structures are as follows:

Systemic circulation ⇒ Right Atrium → [Tricuspid Valve] → Right Ventricle → [Pulmonary Valve] → Pulmonary Artery ⇒ Pulmonary circulation

Pulmonary circulation ⇒ Left Atrium → [Mitral/Bicuspid Valve] → Left Ventricle → [Aortic Valve] → Aorta ⇒ Systemic circulation

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given
alexandr402 [8]

Use the slope-intercept form to find the slope.

Tap for fewer steps...

The slope-intercept form is  

y = m x + b  

where  m  is the slope and  b  is the y-intercept.

y = m x + b  

Using the slope-intercept form the slope is  

− 4 . m = − 4

To find an equation that is parallel to  

y = − 4 x + 2

the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

( − 2 , 5 ) m = − 4

Using the point-slope form  

y − y 1 = m ( x − x 1 )

plug in  

m = − 4 ,  x 1 = − 2

and  

y 1 = 5 . y − ( 5 ) = ( − 4 ) ( x − ( − 2 ) )

Solve for  

y .

Multiply  

− 1  by  5 . y − 5 = ( − 4 ) ( x − ( − 2 ) )

Simplify  

( − 4 ) ( x − ( − 2 ) ) .

Multiply  

− 1  by  − 2 . y − 5 = − 4 ( x + 2 )

Apply the distributive property.

y − 5 = − 4 x − 4 ⋅ 2

Multiply  − 4  by  2 . y − 5 = − 4 x − 8

Move all terms not containing  

y  to the right side of the equation.

Add  

5

to both sides of the equation.

y = − 4 x − 8 + 5  Add  − 8  and  5 . y = − 4 x − 3

HOPE THIS HELPED!
