Ans.
Escherichia coli is a facultative anaerobic, gram-positive bacterium that can survive in absence or presence of oxygen. When oxygen is available in its surrounding, it shows respiration, in which complete breakdown of glucose takes place to produce energy. However, in the absence of oxygen, it shows fermentation for energy generation.
Hence, the correct answer is 'option d). in aerobic conditions, it will show respiration, and in anaerobic conditions, it will show fermentation.'

The major has that increases the Greenhouse Effect is Carbon
Answer:
B. The vacuole is not full and the plant is wilted
Explanation:
When a plant cell is placed in a hypertonic solution, the water inside the cells is drawn out by osmosis. The vacuoles decrease in size. The cytoplasm also shrinks away from the cellulose cell wall and plasmolysis occurs. This causes a lack of structure for the plant and causes it to wilt, or become flaccid.
There are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.
<h3>Disaccharides</h3>
- Disaccharides are carbohydrate compounds containing two monosaccharide units linked together by glycosidic bonds
Examples of disaccharides include sucrose and maltose.
- The ratio of hydrogen to oxygen atoms in a carbohydrate is always a 2:1.
For example, the formula of sucrose is C₁₂H₂₂O₁₁
> The ratio of hydrogen to oxygen atoms is 2;1
Therefore, there are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.
