• Homeothermal
• Homeostasis

What does the picture show?

• Vasoconstriction is when blood vessels near the surface become narrower

• Vasodilation is when the blood vessels near the surface become wider

• Vasodilation allows the body to lose excess heat

• Vasodilation allows the body to gain excess heat

Sweating is........

• a type of osmoregulation

• a type of thermoregulation

• very good at removing heat as it evaporates

• good at cooling the body as water coats the surface and makes it cooler

Shivering is an involuntary response to low body temperature. It is an example of a homeostasis mechanism called osmoregulation.

• TRUE

• FALSE

In cold temperatures, the body restricts blood flow to the skin to keep warm blood close to the core. What is this called?

• Vasodilation

• Shivering

• Vasoconstriction

• Thermostasis

what is osmoregulation?

• Control of water and salt in the body

• Control of blood pressure in the body

• Control of blood glucose in the body

Which picture shows a fish in a hypertonic solution?

• TOP

• BOTTOM

NGSS.HS-LS1-3

In an isotonic solution which way will the water flow

• it will not flow at all

• it will flow into the cell

• it will flow both ways at equal rates

• out of the cell

Clownfish and other saltwater fish cannot survive in freshwater because:

• freshwater is hypertonic to their cells and will result in water leaving them, causing the cells to shrink

• freshwater is hypotonic to their cells and will result in water leaving them, causing the cells to shrink

• freshwater is hypertonic to their cells and will result in water entering them, causing the cells to swell and burst

• freshwater is hypotonic to their cells and will result in water entering them, causing the cells to swell and burst
