يجب الإجابة على هذا السؤال

سؤال رقم - 2

2.Ice fish are unique because they have:

Hemoglobin in their blood

Compressed body

Large fins

Bright colors

يجب الإجابة على هذا السؤال

سؤال رقم - 3

3.Salmon are known for their ability to:

Live only in saltwater

Migrate upstream to spawn

Change colors

Breathe air

يجب الإجابة على هذا السؤال

سؤال رقم - 4

4.What adaptation helps amphibians survive in both aquatic and terrestrial environments?

Gills

Lungs

Moist skin

All of the above

يجب الإجابة على هذا السؤال

سؤال رقم - 5

5.What is the primary function of contractile vacuoles in freshwater protozoa?

To aid in movement

To store food

To regulate water balance

To perform photosynthesis

يجب الإجابة على هذا السؤال

سؤال رقم - 6

6.In freshwater environments, organisms face challenges due to:

High salinity

Low oxygen levels

Osmotic pressure

Extreme temperatures

يجب الإجابة على هذا السؤال

سؤال رقم - 7

7.Osmosis is defined as:

The movement of solutes across a membrane

The movement of water across a selectively permeable membrane

The process of gas exchange

The method of cellular respiration

يجب الإجابة على هذا السؤال

سؤال رقم - 8

8.What happens to a freshwater fish in saltwater?

It absorbs water

It loses water

It becomes buoyant

It thrives

يجب الإجابة على هذا السؤال

سؤال رقم - 9

9.Which of the following correctly describes osmotic pressure?

The force exerted by solutes in a solution

The pressure exerted by water molecules only

The amount of gas dissolved in water

The pressure in fish gills

يجب الإجابة على هذا السؤال

سؤال رقم - 10

10.What is a key difference between cellular respiration and gas exchange?

Cellular respiration occurs in all organisms

Gas exchange occurs at the cellular level

Cellular respiration produces energy, while gas exchange involves the transfer of oxygen and carbon dioxide

Gas exchange is only in aquatic organisms

يجب الإجابة على هذا السؤال

سؤال رقم - 11

11.How do ice fish see in dark and deep ?

eyes

low-density body fluids

air sacs

swim bladders

يجب الإجابة على هذا السؤال

سؤال رقم - 12

12.Which adaptation is crucial for salmon before their migration?

Smoltification

Weak swimming muscles

Color-changing skin

Contractile vacuoles

يجب الإجابة على هذا السؤال

سؤال رقم - 13

13.Amphibians typically return to water to:

Lay eggs

Breathe air

Hunt for food

Hibernate

يجب الإجابة على هذا السؤال

سؤال رقم - 14

14.What role do gills play in the adaptation of aquatic animals?

They help in buoyancy

They facilitate gas exchange

They store food

They provide camouflage

يجب الإجابة على هذا السؤال

سؤال رقم - 15

15.Eel electric are known for their ability to:

Large gills

Generate electricity

Change color

Swim against strong currents

يجب الإجابة على هذا السؤال

سؤال رقم - 16

16.Which of the following is NOT a feature of amphibians?

They have a dual life stage

They are strictly aquatic

They have permeable skin

They undergo metamorphosis

يجب الإجابة على هذا السؤال

سؤال رقم - 17

17.What is the primary adaptation of sharks?

Strong olfactory senses

control level of urea

Colorful scales

Long fins

يجب الإجابة على هذا السؤال

سؤال رقم - 18

18.How does osmosis affect a freshwater organism placed in saltwater?

Water enters the organism

Water exits the organism

No change occurs

Oxygen enters the organism

يجب الإجابة على هذا السؤال

سؤال رقم - 19

19.What is a major benefit of the contractile vacuole for protozoans?

It aids in reproduction

It helps with locomotion

It prevents cell bursting due to excess water intake

It allows for photosynthesis

يجب الإجابة على هذا السؤال

سؤال رقم - 20

20.Which adaptation helps amphibians to absorb moisture from their environment?

Lungs

Scales

Permeable skin

Thick fur
