Answer:
A. The bacteria are breaking down sugars in the absence of oxygen.
Explanation:
Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers. 
They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen. 
In Glycolysis: 
 2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.
Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.

<span>The answer is to control the crossing of the traits.
The idea of preventing plants from self-pollinating is to control the crossing of the traits. If plants were self-pollinating, he could not know if the traits are inherited from the same plant or from the other. By preventing this, he could cross parents with known phenotype and that way learn about crossing process and inheriting process.</span>

Answer:
Due to early flowering in the mustard plant.
Explanation:
The scientists discovered that the flowering time of the field mustard had changed by observing more mustard plants which produces earlier flowers. The behaviour of the mustard plant change due to the change that occur in the environmental conditions that leads to early flowering in mustard plant. If this early flowering occurs for more generation, then the mustard plant will adopt this type of behaviour in normal environmental conditions that experience by the mustard plant.
