Answer:
Carbon sources
Carbon sequestration
Explanation:
Carbon sources are regions that produces atmospheric carbon dioxide. This carbon dioxide is naturally added to the atmosphere when organisms respire, decompose, rocks with carbonate are weathered and volcanoes erupt.
Carbon sequestration is the process of taken and storing atmospheric carbon dioxide. The method helps in reducing the amount of carbon dioxide in the atmosphere which in turn reduces global climate change.
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
The slightest change in pH can destroy the substance or organism. The pH of a cell's interior helps regulate the cell's chemical reactions. For example, the pH of blood is 7.4, if blood falls to 6.8 or lower or 8.2 or higher, it results in death.
Answer:
Ego
Explanation:
In 1923, Sigmund Freud's personality theory was structured into three different parts viz: Id, ego and superego
The id is the instinctive and unconscious part of the personality which responds directly to urges, needs and desires. The id operates on the pleasure principle that every wishful impulse should be satiated instantly regardless of the resulting effect.
The ego is the part that mediates between the unreasonable id and societal beliefs. It is the reasoning and decision-making component of the psyche.
The superego is the part that acts as a self critical conscience, reflecting the social standards that has been learnt
In this scenario involving Cecil, the id part of his personality is responsible for the sexual attraction to his English teacher but the ego part of his personality is making him realize that is socially unreasonable for his teacher to respond to his sexual advances. His ego, which operates with the reality principle is restraining him from acting from his feelings in consideration of social realities.
Therefore, his ego is restraining him from expressing his feelings of sexual attraction (Id) considering societal consequences.
