Answer:
B. Motivation
Explanation:
Self efficacy involves a strong belief by individuals in themselves in doing certain tasks or assignments.
Dale Schunk who was a psychologist applied the concept of self-efficacy to many aspects of students' achievement. He discovered that self-efficacy influences a student's motivation, learning and increases productivity.
Answer:
The answer is labor shortages.
Explanation:
A labor shortage can be defined as a condition related to the economy in which employers consider that there are not the necessary qualified candidates or employees who can be in charge of the different demands concerning the marketplace.
This situation is usually considered by economists as "an insufficiency in the labor force." Wage levels are considered a factor to measure a labor shortage. However, that factor is not usually related to the way through which people perceive things.
1. Samples of a microbial colony obtained from the natural environment are not pure culture. They are mixed cultures because the environment consists of an array of microorganisms and not one specific organism. A sample obtained from the natural environment such as water or soil may contain several species of microbes that need to be further isolated to obtain a pure culture.
2. Isolation streak plate technique involves the dilution of the sample several folds and then streaking a small amount using a sterile inoculation loop on an agar plate in a zig-zag manner. This is done to obtain a pure culture of bacteria from a mixed population by separating the microprocessor. When the sample is diluted into a small concentration and is streaked onto agar placed, widely spaced, discrete colonies of bacteria can be observed. These isolated colonies can be further cultured to obtain pure cultures by picking and re-streaking them on fresh agar plates.
3. A microbial colony is considered a pure culture because it consists of single species. A single species of bacteria cluster and form an isolated colony on an agar plate which can be further plated on fresh medium.
3-1 - If your agar plate shows discrete uncluttered colonies then you have obtained an isolated colony. The following picture might help you to understand.
3-2. If you subculture isolated microbes into a sterile nutrient broth without any contamination, it will still be considered pure culture because it is single isolated species in a sterile aseptic environment of the nutrient broth.
3.3. A pure culture can become a mixed culture due to contamination. This could be caused by airborne bacteria if your conditions are not aseptic. Contamination is possible if the work area is not clean and sterile or if the glassware is not sterile. The contamination can transform your pure culture into a mixed culture and is hence problematic. So, it is very important to maintain a sterile and aseptic environment, glassware, and instruments.

Answer:
development of the myelin sheath
Explanation:
Motor development: The term motor development refers to a process that involves a child's development of muscles and bones and the capability to manipulate and move over the surrounding environment of the child.
Types:
1. Fine motor development.
2. Gross motor development.
Development of the myelin sheath: Each myelin sheath in an individual's body id being formed via concentric wrapping of Schwann cell and an oligodendrocyte which is found around the axon. The development of an individual's myelin sheath is responsible for motor development.
