Answer:

\boxed {\tt A. \ Water \ moving \ into \ the \ root \ cells \ of \ a \ plant}

A. Water moving into the root cells of a plant

Explanation:

First, let's define osmosis.

Osmosis

The movement of a solvent, usually water, through a semipermeable membrane to balance the concentration of a substance.

Since it involves the diffusion of a solvent, which is usually water. Therefore, the answer choice that involves the movement of water will be correct.

The best answer choice is A. water moving into the root cells of a plant

Find the area of a parallelogram if a base and corresponding altitude have the indicated lengths. Base 1 1/2 feet, altitude 6 in

Butoxors [25]

Area of a parallelogram = A =base*height

so in this case is just (1½)(6).

first off let's convert the mixed fraction to "improper",

$\bf \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}
\\\\\\
\cfrac{3}{2}\cdot 6\implies \cfrac{18}{2}\implies 9$

What is the solution to the following system of equations? x+y=5

marta [7]

Answer:

(3,2)

Step-by-step explanation:

Let's solve this via elimination method:

$\begin{cases} x+y=5\\x-y=1\end{cases}$

By subtracting equation 2 from equation one we obtain:

$\begin{cases} x+y=5\\-(x-y=1)\end{cases}\\\\0x+2y=4\\\\y=2$

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

$x+y=5\\\\x+2=5\\x=5-2\\\\x=3$

Therefore the solution for the system of equations is:

x=3 and y = 2 as an ordered pair we have (3,2)

motorcycle cover 210 kilometre distance with 5 l of petrol how many kilometre does it cover with 8 litre of petrol? how much pet

Likurg_2 [28]

Answer:

A: 336 km

B: 14 L

Step-by-step explanation:

Use a proportion

210 km / 5 L = x / 8L Cross multiply

8*210 = 5 x

1680 = 5x

x = 1680 / 5

x = 336 km

===============

210 /5 = 588/x Cross multiply

210x = 588 * 5

210x = 2940 Divide by 210

x = 2940/210

x = 14 L
