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.
I believe it is the second one not 100% sure so don't blame me if you fail.

- The site of protein synthesis in plants is the <u>ribosomes</u>.
- The cell organelle absent in a plant cell is <u>centrosomes</u>
Explanation:
The nitrates absorbed by the plant roots are converted into various types of amino acids (about 20 types) which sequences respectively to form polypeptide chains of various protein molecules in the ribosomes. The ribosomes are either free floating in the cell cytoplasm or attached to the endoplasmic reticulum.
Centrosomes present in animal cells involves in spindle and microtubule formation during mitotic cell division; however, in plant cells, centrioles or centrosomes are absent, but still microtubule formation takes place through mitotic phases of cell division.
