The defense mechanisms where one imposes one's own unacceptable impulses or wishes onto another person is_______________.
enot [183]

Answer:

Sublimation

Explanation:

People tends to have thoughts, feelings, impulses, and memories that can be difficult to deal with. In psychoanalytic theory, Sublimation is a defense mechanism in which people metamorphose or modify their hindered and inconsistent challenged emotions or unacceptable impulses into a social behavioral way that is accepted and profitable. For example, an individual that is always aggressive over the slightest little mistake or argument can take up a military school to join the troop of an army. He can use his role as a soldier as an outlet to vent his aggression and frustration into socially acceptable ways by dealing with those who fails to comply to the law.

Which of the following must exist in a population before natural selection can act upon that population? A. genetic variation am
just olya [345]
<h2>Answer is Option "A"</h2>

Explanation:

  • Genetic variation is the variation in alleles and genes, both within and among populations. Think of a population as a family unit. Within your family of closely-related individuals there is genetic variation. Within a neighbourhood, there are many families, and so there is also genetic variation among that larger group
  • Genetic variation can be identified through either continuous or discrete traits. Continuous traits are traits that vary continuously, such as height and weight. Discrete traits are traits that can only be measured discretely, such as tongue rolling; you either can or can't do this
  • There are three sources of genetic variation: mutation, gene flow, and sexual reproduction.A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population.Because of this, mutations are usually selected against through evolutionary processes
  • Hence, the right answer is option A "genetic variation among individuals"
