Answer:
taking the pretest
Explanation:
A one-group pretest–posttest design is a type of research design generally used in behavioral research aimed at estimating the treatment effects on the sample. In this experimental design, the target group of participants is first pre-tested on the dependent variable and, subsequently, post-tested after the administration of a treatment. In consequence, the participants of the target group receive the same treatment and assessment. The problem of testing effects indicates that testing may become a problem when the pretest may change participant's behavior. When there are statistically significant differences between the pretest and posttest data, it is possible to support the working hypothesis.
Answer:
Gradually released into the atmosphere by photosynthetic microbes, it formed two important gases new to fledgling Earth: breathable oxygen gas, or O2, and ozone, or O3. Together, the buildup of these gases enabled life to emerge onto land and evolve into the rich diversity of life-forms that inhabit Earth today.

In such pedigree, there are some signs that are used to express such as blank shapes represents normal individual, half-filled shapes represents a carrier individuals, and complete or fully filled shapes represent the affected individuals.
Lisa and Monica are half-filled circles which means they are carriers for the disease. Sam, Tim, Bella, and Joshua have filled-in shapes in the illustrated pedigree. Which means they are affected by the disease.
Here is an explanation of how to do that. Hope it helps!
