Answer:
How the gelatin is prepared can affect the result.
Explanation:
To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.
Osmosis is the diffusion of water. Water tends to diffuse to the area with a higher concentration of solute. (Particles) In this case, Im assuming the fertilizer is the solute because it contains chemicals. Therefore, since water tends to diffuse to higher concentration of solute, the water in the grass will diffuse out to dilute the fertilizer on the surface of the grass. Without water, the grass will be dehydrated and shrivel up and die. Hopefully you find my answer helpful!
The normal blood pH for adult humans is 7.40, and this pH value is vigorously defended at normal body temperature
Acid base Homeostasis is the method by which body keeps a constant ph
pH is kept under check via different systems
1. Chemical system :bicarbonate buffer system(explained below )
Respiratory component :
2. Respiratory Component: The second line of dense is rapid consisting of the control the carbonic acid concentration in the ECF by changing the rate and depth of breathing by hyperventilation or hypoventilation. This blows off or retains carbon dioxide (and thus carbonic acid) in the blood plasma as required
3.Metabolic component : third line of defense is slow, best measured by the base excess,eand mostly depends on the renal system which can add or remove bicarbonate ions to or from the ECF.Bicarbonate ions are derived from metabolic carbon dioxide which is enzymatically converted to carbonic acid in the renal tubular cells.There, carbonic acid spontaneously dissociates into hydrogen ions and bicarbonate ions.When the pH in the ECF falls, hydrogen ions are excreted into urine, while bicarbonate ions are secreted into blood plasma, causing the plasma pH to rise.The converse happens if the pH in the ECF tends to rise: bicarbonate ions are then excreted into the urine and hydrogen ions into the blood plasma.
Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system’s pH within a narrow range.
Maintaining a constant blood pH is critical to a person’s well-being. The buffer that maintains the pH of human blood involves carbonic acid (H2CO3), bicarbonate ion (HCO3–), and carbon dioxide (CO2). When bicarbonate ions combine with free hydrogen ions and become carbonic acid, hydrogen ions are removed, moderating pH changes. Similarly, excess carbonic acid can be converted into carbon dioxide gas and exhaled through the lungs; this prevents too many free hydrogen ions from building up in the blood and dangerously reducing its pH; likewise, if too much OH– is introduced into the system, carbonic acid will combine with it to create bicarbonate, lowering the pH.
Example: Antacids, which combat excess stomach acid, are another example of buffers.
ECF =Extra cellular fluid
The answer is II.Sexual reproduction results in more diversity
1,bc the prefix auto=self, like in the word autobiography, where this can be translated into self-biography, or self-writing
