Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

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.
Ans.
A monohybrid cross can be defined as 'a cross between two individuals having different copies of a chromosome or gene of interest, which is responsible for variations in a single trait.'
These variations in a single trait are controlled by two or more alleles for a single chromosomes. For example, a cross between tall pea plant and dwarf pea plant to study the inheritance of plant height.
Thus, the correct answer is 'option). they differ in a single trait.'
