Answer:
Option-B
Explanation:
Heredity refers to the passing of the traits from the parents to the offsprings or generation and also known as inheritance and Genetic variation is the difference in the genetic material in population which leads to the formation of a variety of traits.
Since the variation in traits is determined by factors (Gregor Mendel) later called "genes" which are passed on to the offsprings, therefore, the branch of biology which studies the pattern of inheritance and variation is known as "Genetics". Gregor Mendel is known as the Father of Genetics.
Thus, Option-B is the correct answer.
Meiosis is involved in the formation of the gametes of multicellular organisms.
<h3>How do multicellular organisms reproduce?</h3>
Both plants and animals reproduce by developing new individuals, through gametes or reproductive cells.
<h3>Characteristics of multicellular organisms reproduction</h3>
- Many multicellular organisms always arise from a single cell called a zygote, the result of the union of two gametes (female and male).
- The zygote subdivides rapidly throughout gestation, forming the entire body of the creature that, from its birth, begins to grow.
Therefore, multicellular organisms reproduce by means of certain types of reproductive cells that are generated and take care of building a complete new individual.

The option that has the most potential of experiencing background extinction based on the natural disruption is : ( C ) A species that will not grow during a specific season every year
<h3>What is Background extinction </h3>
Background extinction is the gradual extinction of species due certian environmental factors such as change in weather conditions, disease, competitive disadvantage and habitat loss.
A population that will not grow during a specific season every year will experiences a gradual extinction process while other options will experience a fast and sudden extinction process.
Hence we can conclude that the most potential of experiencing background extinction based on the natural disruption is : A species that will not grow during a specific season every year.

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.
The tongue muscle that the child uses when she sticks her
tongue out is the genioglossus. This is the muscle of the tongue that is
responsible for making the tongue to stick out or protruding the tongue of an
individual.
