The rigth answer is the picture 4.
In the case of a hypotonic extracellular medium, there will be a large inflow of water to dilute the Na, thereby increasing the cell volume and there will be an explosion of the membrane in places so hemolysis, the contents of the red cell ( Hemoglobin) is released into the blood plasma.
On the other hand, in the case where the extracellular medium is hypertonic, therefore archi concentrated, well it will be the water of the red cell that will come out without damaging the membrane, we will rather have a red cell that is completely flat and non-functional without release. erythrocyte (Hb) content.
Answer:
The correct answer is 3. sugars
Explanation:
During photosynthesis, the light energy is captured by the chlorophyll and this energy is used in the formation of sugar molecules with the help of water. Oxygen is released as the byproduct of this process.
So the light energy which is captured is stored in the bonds of sugar and when this bond is broken down during oxidation the energy is released and converted into another form which is ATP and this ATP is called the energy currency of the cell. This ATP is used in many metabolic processes. Therefore the correct answer is sugar.
Organisms that survive a new environment are said to have adapted to their surroundings.
