What molecules are needed to maintain homeostasis in biosphere 2
ruslelena [56]

Answer:

What molecules are needed to maintain homeostasis?

Homeostasis is maintained by many cellular processes that require ATP. Aside from enzymes the make and break bonds, other proteins that use ATP include protein pumps that move salts across a membrane.

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!
