Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
Answer:
Every fossil tells us something about the age of the rock it's found in, and index fossils are the ones that tell us the most. Index fossils (also called key fossils or type fossils) are those that are used to define periods of geologic time
Explanation:
One of the common arguments why the process of transplanting non-human organs which came from animals may be considered as an ethical act is that antigens on the surface of the non-human organs are not significantly rejected in the process. Although its research is still substantial, it is still considered as a matter of ethical issue.
The effect of temperature on gas production in yeast;
As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in tempmoreerature.
<h3>An experiment to show the effect of temperature on gas production in yeast.</h3><h3 />
If temperatures affect the growth of yeast and the amount of carbon dioxide gas produced then when the yeast is placed for instance in 75 degrees, the carbon dioxide levels will be than the carbon dioxide levels at room temperature (69 degrees), and 40 degrees, because heat activates the enzyme molecules to move faster
Yeast at an optimal temperature to produce the same amount of CO2 as yeast below or above it. ... Enzymes involved in yeast cell metabolism start to denature above-optimal temperatures, resulting in a decrease in both metabolic rate and CO2 production.
