The statement that will correct the error in Edwin's notes is as follows:
Thus, the correct option is A.
The electrically charged objects produce attraction of oppositely charged objects. For example, if a positively charged object and a negatively charged object bring close to each other, they interact with one another. Their forces act in the same direction. i.e. from the positive to the negative charge.
There is an interaction between two oppositely charged objects required in order to furnish attraction, while there is an interaction between two identical charged objects required in order to furnish repulsion.
Whether it is attraction or repulsion, it must be required that an electrically charged object needs to touch an uncharged object.
Therefore, the correct option for this question is A.

The elevator at a factory moves materials around the building.
The boss at a factory gives out orders and directions.
The boxes at a factory are used to ship materials to customers.
O
Answer:
The boss at a factory gives out orders and directions.
Explanation:
The nucleus is an organelle that is enclosed by nuclear membrane and carry genetic material in eukaryotic cells.
The role of nucleus is to monitor and control the functioning of different activities such as growth and metabolism of the cell and also transfers the hereditary information. Likewise boss of a factory gives out orders and directions to regulate the factory properly.
Hence, the correct option is "The boss at a factory gives out orders and directions."
Answer:
Enzymes are proteins that act as catalysts for reactions, such as those in cellular respiration. They increase the likelihood of a reaction by lowering the energy required for a reaction to occur. In the process, enzymes are left unchanged by the reaction. ... The resulting molecules from the reaction are called products.
Explanation:
bronchi
trachea
bronchioles
alveoli
Answer:
Alveoli
Explanation:
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
polymers
water and polymers
none of the above
Answer:
Water and polymers.
Explanation:
Dehydration reaction may be defined as the reaction in which a water molecule is released during the process of reaction. Large molecules are joined together by the process of dehydration.
Polymers are formed by reacting the monomers together with a release of small molecules like water. Hence, water and polymers are formed by dehydration reaction.
Thus, the correct answer is option (3).
Dehydration synthesis leads to the formation of water and polymers. Hence, the correct option is C.
Dehydration is the process of water loss. It involves the formation of two smaller molecules to form a larger molecule with a loss of water. The macromolecules like carbohydrates, proteins, and nucleic acids, are synthesized by a dehydration process which is essential for the survival of living organisms.
Thus, the dehydration synthesis leads to the formation of water and polymers. Hence, the ideal solution is option C.
