Two types of stressors that learners are likely to experience in a post school destination as a college or university or the wor
makvit [3.9K]

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.

Explain how studying viruses led to the discovery that DNA contains genetic material
Ainat [17]

Answer:

See below

Explanation:

Hershey and Chase Experiment:

Viruses, such as T2 Bacteriophage infect by injecting their genetic material into a cell. When Hershey and Chase used radioactive isotopes of sulfur (marking proteins) and phosphorous (marking DNA) and saw which was injected into the cell by the T2 Bacteriophage, sulfur was found outside while phosphorous was found inside the cell. That means that DNA was injected into the cell, not proteins. As the genetic material is injected into the cell to hijack it, and as DNA was injected inside while proteins remained outside, DNA is the genetic material.
