These fibers are the protein filaments that cause contractions in the structure of the muscle. Weight training tones muscles by increasing the number of myofibrils in a sarcomere, thus increasing its capacity to produce force.

Answer:
financial stress and family stress
Explanation:
When learners go to college or a university, their family expects a lot from them especially when the parents are the ones who brought the learner to study. This causes stress on the learners. Choosing the major can also be stressful, especially when the family intercedes in the learner's decision. This also creates a financial burden on the learner, especially when the learner supports himself. So,<em> he has to balance studying while working.</em> If he has a scholarship, he has to maintain his grades in order to keep up.
In the same way, <u>a person who goes to the workplace is also expected by his family to provide them financially.</u> This creates a financial stress on his end. Besides this, he is also expected to make commitments especially when he has children. He needs to balance working while taking care of his kids and attending to their needs at home and in school. This is how family stress can affect him.
