Horace Danby is a thief, who steals rare books every once a year. He has a uniqueness in his stealing ways. Even at the age of 50 he is yet unmarried and people think of him as a man who is honest and kind in nature. He has a good reputation among the social stratification.
About 15 years ago, he was also sent to jail because he stole some rare books. The purpose of stealing rare books was that he liked collecting rare books. However, now he was doing full fledged robberies, that too with the purpose of buying rare books.
Another trait described about Horace is that he was allergic to flowers and this is how he actually got caught for a jewel robbery.

| Breathing involves the process of inhaling oxygen and exhaling carbon dioxide | Respiration is the process of breaking down of glucose to produce energy which is then used by cells to carry out the cellular function. |
| Breathing takes place in the lungs. | Respiration takes place in cells. |
| Breathing is a voluntary physical process. | Respiration is an involuntary chemical process. |
| No energy is produced during the process. | Energy is released in the form of ATP. |
| It is an extracellular process, as it occurs outside cells. | It is an intracellular process, as it occurs inside cells. |
| No enzymes are used during the process. | A large number of enzymes are used during the process. |
| Breathing takes places through respiratory organs like lungs, nose, etc. | Respiration takes place in cells and cell organelles like mitochondria, etc. |

Respiration is a process in which glucose is broken down with the help of oxygen and energy is released along with the production of carbon dioxide and water.
There are two types of respiration i) aerobic respiration ii) anaerobic respiration.
Aerobic respiration- the process of respiration that takes place in the presence of oxygen.
Example- glucose(a 6-carbon molecule) breaks into pyruvate(a 3-carbon molecule) and in the mitochondria pyruvate is broken down into 3 molecules of carbon dioxide and water with the release of energy.
Glucose --> pyruvate + energy à carbon dioxide + water + energy.
Anaerobic respiration- the process of respiration that takes place in the absence of oxygen.
Example-
- In yeast cells, glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to ethanol(a 2-carbon molecule) and carbon dioxide.
Glucose --> pyruvate + energy --> ethanol + carbon dioxide + energy.
- If there is a lack of oxygen in our muscle cells, pyruvate breaks in a different pathway. Glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to lactic acid (a 3-carbon molecule) along with the release of energy.
Glucose -->pyruvate + energy --> lactic acid + energy.

p(x)=x3−6x2+11x−6
p(x)=(x−3)(x2−3x+2)
p(x)=(x−3)(x2−2x−x+2)
p(x)=(x−3)(x−1)(x−2)
(x−1)(x−2)(x−3)=0
x=1,2,3
Thus, the other two zeroes of the polynomial are 1 and 2.

Stomata are small pores or opening present in the epidermal cells of leaves. They open during the day and close during night. They take carbon dioxide required during photosynthesis during the day. Also, they release excess water released in the process of respiration during the night along with carbon dioxide. This opening and closing of stomata is controlled by concentration of solutes in the guard cell.
During daytime, the pH of the guard cells is alkaline. This results in the hydrolysis of water. The solutes from neighbouring epidermal and mesophyll cells enter the guard cells and lowers the osmotic potential and water potential of guard cells. This lowered water potential and osmotic potential allow the movement of water into guard cells from neighbouring cells. Due to this, guard cells become turgid. This results in the opening of the guard cells. During night time, carbon dioxide accumulates in the guard cells. Hence, it becomes acidic. The acidic pH favors the formation of starch in the guard cells. Hence, the solute concentration decreases. This makes the water from the guard cells to move away into neighbouring cells. The guard cells then become flaccid with no water. They collapse against each other and result in the closing of stomata.
