The variable, by changing its values to reciprocate change in the values of the independent variable is called the dependent variable.

The independent variable is act as  the experiment controller whereas, the dependent variable act as experiment measure.

An independent variable is a cause whereas the dependent variable is an effect of that cause.

we can say in a linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable.

An independent variable does not rely on anything, while the dependent shows the effect, due to changes in independent variable.

Thus option A is correct.

can anybody help me with this?

Answers

Answer:

presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits

in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance

sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them

the sugar dissolves in water, creating a sugar solution

this results in fruits with less water inside them, and surrounded by sugar solution

A car drives 150 m to the east then backtracks 30 m to the west. Describe the mathematical operation you will use to determine the net movement of the car.

Answers

Answer:

Subtraction operation

The car's displacement is  120 m west

Explanation:

Given;

first motion of the car as 150 m east

second motion of the car as 30 m west

The mathematical operation that will be used to determine the net movement of the car is subtraction operation.

The net movement of the car is the car's displacement.

Displacement is given by;

D = final position - initial position

D = 30 m - 150 m

D = - 120 m

The negative sign is direction = west ward direction

Thus, the car's displacement = 120 m west

how does the concentration of electrolytes in and outside a cell control the movement of water

Answers

Answer:

Maintaining an isotonic environment for the cell ensures that the cell does not shrink or swell due to water.

Explanation:

If the cell was in a hypotonic solution, water would rush in the cell causing it to burst, and if it was in a hypertonic solution it would cause water to move out of the cell, causing the cell to shrivel. It is important that the cell is always in a solution with an almost equal electrolyte solution inside the cell
