<span>Mostly all ionic compounds dissolves in water because molecules present in the water hydrates the ions. Water is a formation of polar molecules hydrogen (partial +ve) and oxygen ( partial -ve) respectively. When a pinch of salt is poured in water, it breaks into na+ (Sodium positive) and Cl- ( chlorine negative) ions respectively and the partially positive hydrogen molecules are attracted to the chlorine anions where as the partially negative oxygen molecules are attracted to the sodium cations Then the formed bond are free to move around the water which makes it to dissolve in water.</span>
Cooperation helps because they both defend each other. its a friendship that allows for living longer. For example, Near sharks, fish stay behind them, so that they are not killed, thats one example.
Answer:
The correct answer is - They have substances that counteract acids or bases to prevent the pH from changing
Explanation:
All living organisms including humans are water-based systems, which implies that they rely intensely upon liquid equilibria, particularly acid-base equilibria. Hence, all the acid-base and pH ideas we have talked about so far are critical to the chemistry of organic or biological systems.
This is particularly significant for enzyme, which are proteins that go about as catalysts for all major biological reactions. Most enzymes just work inside a specific pH range. Because all natural cycles are subject to pH, cells and creatures must keep up a particular and consistent pH so as to keep their compounds in the ideal condition of protonation they have specific substances that counteract the acid and base to maintain pH.
for instance:
The pH of the Cytoplasm is maintained by the phosphate ion
The pH of the blood is regulated by the bicarbonate ion
Chloroplast are found mainly in the leaves, this is because they are used in photosynthesis to produce food for the plant . The reason they are in the leaves is because the leaves have a large surface area which helps absorb more sunlight than any other parts of the plant and sunlight is required for photosynthesis.
It is in greater amount in the month when the sun shines at its most. July is one of of the month.
