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.
The correct answer is A. Lac repressor.
Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.
Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.
When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
Animals help plants by pollinating them, helping them to disperse seeds.
