Answer:

The membrane is made from polar phospholipids allowing water to move freely in and out of the cell

Explanation:

The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.

The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.

What is translocation in plants? ?
seraphim [82]

Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.

Which diagram best illustrates what happens when electromagnetic waves strike a rough, dark material?
muminat
When electromagnetic waves strike an obstacle, what usually happens is that part of the wave is absorbed by the obstacle, part is reflected back and part is transmitted through the material.
However, in case of a dark object; the dark object acts as a perfect absorber and absorbs all the electromagnetic waves.
So, the right answer is the diagram showing only absorption of the wave by the surface.

Learning Task 2. Find the equation of the line . Write in slope intercept form
Damm [24]

Answer:  

(1)  m = -5, b= 1

    \frac{x}{a} + \frac{y}{b} = 1  

put b=1 (given)

\frac{x}{a} + \frac{y}{1}  = 1 => y = -x/a + 1

-1/a is representing slope here which is given as -5

-1/a = -5 => a = 1/5

slope intercept form

y = mx +b

y = -5x + 1

standard form

5x +y = 1

(2). (1, -2), (3, 3)

m = 5/2

slope intercept form

y - 3 = 5/2*( x -3)

y = 5x/2  -9/2

standard form

5x -2y = 9

(3). (-2, 0) and (0,5)

  m = 5/2

slope intercept form

y - 0 = 5/2 ( x+2)

y = 5x/2 + 5

standard form

5x -2y = -10

(4). a = 2, b = -7

   \frac{x}{2} + \frac{y}{-7}  =1

slope intercept form  

y = 7x/2 -7

standard form

7x -2y =14

(5). m=2,(3,-1​)

  slope intercept form  

y +1 = 2(x -3)

y = 2x -7

standard form

2x -y = 7

In coral reefs, clownfish live unharmed among the poisonous tentacles of sea anemones. The sea anemones protect the clownfish fr
slava [35]

Answer:

The sea anemone and the clownfish live together in a type of symbiotic relationship called mutualism, where both species benefit from the other. The sea anemone offers the clownfish protection and leftover food

The anemone's tentacles provide the clownfish with protection from predators, while the clownfish chase away butterfly fish that would eat the anemone. ... Sea anemones can do very little to control the flow of water across their bodies, and they rely on local currents to bring in oxygen and nutrients.Clownfish perform an elaborate dance with an anemone before taking up residence, gently touching its tentacles with different parts of their bodies until they are acclimated to their host. A layer of mucus on the clownfish's skin makes it immune to the fish-eating anemone's lethal sting.Instead, both species have evolved behaviors that help them avoid being eaten while they graze for benthic algae. Butterflyfish typically swim in pairs near a particular clump of coral. ... An anemone robbed of its clownfish guards will quickly fall prey to the voracious butterflyfish.
