The differences in populations are

(Colors)

(Look)

(Shape)

And (Form)

The slight color can be important because of camouflage.

The color can also make the organism look like a different animal.

Lets put snakes for example...

there are also some harmless snakes that are often confused with the coral snake, the shovel-nose snake, the scarlet kingsnake, the Florida scarlet snake, the Pueblan Milk Snake, and other snakes that look like coral snakes.

They do this so they look like a very dangerous animal and dont get hunted.

What does it mean to have a hypotonic solution?

Dmitriy789 [7]

Answer:

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Answer:

C. surface tension

Explanation:

Surface tension refers to the property of water or any liquid to enhance its surface area by a certain amount. It is a very important property of water due to which it resists any external force due to cohesive nature of water molecules.

How surface tension help needle to float on water:

It is a property of water which enhance the attractive force between needle and liquid.

The molecules on the surface of water do not have any force acting from upwards because that side is exposed to atmosphere. This causes a downward force but no upward force on upper surface,so the molecule of surface tend to stay together by forming a thin sheet or imaginary layer.

If weight of any material cannot break surface tension it will float on water surface. This is what happens with needle.Therefore, when needle is placed on water surface with alot of care in horizontal direction, it will not break surface tension and hence will float on water. Please see attached image for better understanding.

Hope it clears up the picture!
