Answer:
The Laura tried to grow micro-organisms in culture broth medium in Petri-plates but the microbial growth was not observed even on the fourth day of culture which could be due to:
1. Laura could have not provided the correct broth medium maintaining the with pH and salt concentrations.
2. Microorganisms did not get optimal growth conditions.
3. The bacterial source could have died after the collection which could have lysed after their death and thus no longer visible.
Incomplete dominance can happen in flowers such as snap dragons where a red flower plant and a white flower plant have an offspring that is neither red nor white but is a mix so in this case it would be pink. It does not support the blending theory as it does not get its colour from the dominant plant in this case but from both.
The reactant that brings about the oxidation is called the oxidising agent, and that reagent is itself reduced by the reducing agent.
Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.
Oxidation is loss of electrons (OIL RIG). Therefore, an oxidising agent takes electrons from that other substance. Therefore, an oxidising agent must gain electrons.
Oxidation happens when an atom loses one or more electrons during a chemical reaction, meaning that its oxidation number increases. This is because the atom loses the negative charge of the electron, which is similar to gaining a positive charge, increasing the oxidation number.
