Define the following :
-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.

How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.
