______ is a defense mechanism that occurs when group members believe the logical, but false explanation of their behavior.
Ede4ka [16]

Answer:

The correct answer is- Rationalization

Explanation:

Rationalization is a defense mechanism that involves the action to justify their unobvious behaviors by logical reasons to avoid true explanation. For example, if an employee is not given promotion might rationalize his disappointment by saying that he does not want extra responsibilities.

Rationalization may help the person to avoid guilt and maintain self-respect when he has done something wrong. Many times rationalization is not harmful to the person but if it becomes a habit of a person it can cause a problem for him and others. Therefore the correct answer is rationalization.

Living things come from other living things through either sexual or asexual reproduction.
Iteru [2.4K]

Explanation:

Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!

When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.

When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.
